Searching for ‘what do Catholics bel’ leads to the core tenets of Catholicism. This faith is built on the belief in the Holy Trinity, reverence for Jesus Christ, the transformative power of the sacraments, and the guiding authority of the Pope. The article ahead navigates these pivotal beliefs, uniting over a billion followers worldwide, without overwhelming you with details or intricate theological language.

Key Takeaways

  • Catholicism holds as central the belief in the Holy Trinity and the divinity of Jesus Christ, who is fundamental to the faith as the Son of God, savior, and founder of the Church.

  • Sacred Scripture, including the Bible with additional texts in the Old Testament, and Sacred Tradition, which includes the teachings passed down since the apostles, are seen as the foundation of Catholic teachings, under the Church’s magisterium.

  • The seven sacraments, particularly Baptism and the Eucharist, are essential in Catholic worship, acting as channels of God’s grace and enabling participation in the life, death, and resurrection of Christ.

Catholic Faith Fundamentals

Illustration of the Holy Trinity

The Catholic faith deeply roots itself in the belief of a triune God: the Father, the Son, and the Holy Spirit, also known as the Holy Trinity. This unity in diversity forms the rock-solid foundation of the Christian religion.

Lord Jesus Christ, the second person of the Holy Trinity, is central to the Catholic faith. Acknowledged as the Son of God, Jesus is recognized as the founder of the Catholic Church, and his life, teachings, and sacrificial death form the cornerstone of Catholic doctrine.

The Holy Trinity

The Holy Trinity concept embodies the Catholic belief of a monotheistic God manifesting in three forms: God the Father, God the Son (Jesus), and God the Holy Spirit. This doctrine asserts that these three ‘persons’ are distinct yet united in essence. The Father is the creator, the Son is the redeemer, and the Holy Spirit is the sanctifier or giver of life. The Holy Trinity is not a contradiction but a manifestation of the divine complexity of God’s nature.

According to Catholic interpretation, the Holy Spirit emanates from both the Father and the Son, a belief stated in the Filioque clause, which is part of the Latin rendition of the Nicene Creed, a central creed of Christianity. This interpretation is rooted in the understanding of the Trinity as one God in three Persons, each equally divine yet distinct in their relationship with one another.

Jesus Christ

Seen as the Son of God, Jesus Christ embodies both complete divinity and humanity. This simultaneous divinity and humanity is referred to as the ‘hypostatic union’ in Catholic theology, which means that Jesus embodies both the divine and human nature, each retaining its separate identity. The incarnation of Jesus Christ, his birth from the Virgin Mary, is of immense importance in the Catholic faith as it represents the belief that the Son of God, while maintaining His divine nature, assumed a human nature.

The crucifixion and resurrection of Jesus Christ form the crux of Christian faith. Catholics believe that through his death and resurrection, Jesus:

  • Defeated death and the devil

  • Delivered all those who have faith in him

  • Is the Son of God

  • Is the victor over death

The resurrection is seen as the proof of these beliefs.

Sacred Scripture and Tradition

Illustration of Sacred Scripture and Tradition

Sacred Scripture and Sacred Tradition form the two foundational pillars of Catholicism. Sacred Scripture refers to the Bible, regarded by Catholics as a living document that continues to communicate with believers in all eras. The Bible, consisting of the Old and New Testaments, is the inspired word of God and serves as a guide for Catholic beliefs and practices.

On the other hand, Sacred Tradition encompasses the teachings, practices, and rituals that have been passed down through successive generations. This tradition safeguards the continuity and authenticity of the faith, complementing and interpreting Sacred Scripture. Both Sacred Scripture and Tradition are under the authority of the Church’s teaching authority, the Magisterium, which is wielded by the Pope and the College of Bishops.

The Bible

The Catholic Bible includes both the Old and New Testaments, and uniquely incorporates additional texts in the Old Testament. It is considered to be ‘inspired by God’, written by human authors under divine influence, and authoritative in matters of faith and practice. The Old and New Testaments are viewed as comprising a cohesive narrative of divine revelation, with the New Testament fulfilling the promises made in the Old.

The teachings of the Bible have a significant impact on Catholic doctrine, encompassing practices such as:

  • confession of sins

  • the sacraments

  • prayer and worship

  • moral teachings

  • social justice

The Catholic Church, one of the prominent Christian churches, has played a significant role in preserving the Bible, underlining the Church’s dedication to upholding and propagating the word of God.

Apostolic Tradition

For Catholics, the Apostolic Tradition plays a crucial role in passing down the message of Christ from the apostles. It includes the teachings, practices, and rituals that have been handed down through successive generations, thereby safeguarding the continuity and genuineness of the faith. This tradition complements and interprets Sacred Scripture, ensuring that the traditions of the Church passed down by the apostles are never contradictory to the Bible.

Significantly, Apostolic Tradition holds an important place in the Catholic faith. It serves as a living link to the earliest days of the Church and provides a context for understanding and interpreting Scripture. It is through this tradition that the fullness of the faith is passed on from generation to generation.

The Sacraments and Their Role

Sacraments are at the heart of the Catholic faith. These are outward signs instituted by Christ to give grace. The Catholic Church recognizes seven sacraments: Baptism, Confirmation, Eucharist, Penance (Reconciliation), Anointing of the Sick, Holy Orders, and Matrimony. These sacraments are classified into three groups: ‘sacraments of Christian initiation,’ ‘sacraments of healing,’ and ‘sacraments at the service of communion and the mission of the faithful’.

Sacraments act as channels of God’s grace and are viewed as potent symbols of grace, instituted by Christ and entrusted to the Church. By them, divine life is dispensed to us. Every sacrament is a celebration of the Paschal Mystery of Christ and a participation in His life, death, and resurrection. It is through the sacraments that we experience and participate in God’s grace and become part of the Church community.


Baptism, as the initial sacrament of the Church, marks the entrance into the Christian life. It has several important aspects:

  • It cleanses the soul of original sin

  • It marks the individual as a member of the Church

  • The ceremony involves the application of water

  • The invocation of the Holy Trinity signifies purification and new life in Christ

Baptism is not merely a symbolic ritual, but a sacrament that:

  • Confers grace

  • Imparts a new spiritual character upon the recipient

  • Is the sacrament of faith which has the Risen Christ as its source

  • Is the offer of salvation for all people

Furthermore, the role of godparents during baptism is important as they are chosen to help the baptized person to lead a Christian life in keeping with baptism and to fulfill faithfully the obligations inherent in it.

Holy Communion

Holy Communion, or the Eucharist, involves:

  • Receiving the body and blood of Christ, symbolizing unity with God and the Church

  • The Eucharist is commemorated during the Catholic Mass through the liturgy of the Eucharist, which involves the offering and presentation of bread and wine

  • The bread and wine are consecrated by the priest

  • The consecrated elements are consumed as the body and blood of Jesus Christ

Receiving Holy Communion is not just a personal act of devotion, but also a statement of community identity. It symbolizes communion with fellow believers, expressing solidarity with the local community and the universal Church.

For Catholics, receiving Holy Communion is a profound, sacred act that nourishes spiritual life and strengthens their union with Christ.

The Church Hierarchy and Leadership

With the Pope as the supreme leader, the Holy Catholic Church follows a hierarchical structure, which can be understood as the Catholic Church defined. The Pope, also known as the Bishop of Rome, serves as the chief pastor of the worldwide Catholic Church. The Church is further organized into dioceses and parishes, each under the supervision of a bishop.

The operational activities of the Church are managed through the Roman Curia, the central governing body of the Church, located in Vatican City.

The Pope

Taking the mantle from the Apostle Peter, the Pope, the Bishop of Rome, leads the Catholic Church spiritually. He holds the keys to the kingdom of heaven, symbolized by the keys on the papal coat of arms. The Pope’s ring, known as the Ring of the Fisherman, signifies his authority as the successor of St. Peter, who was a fisherman by trade.

The Pope is chosen through a process known as a conclave, where the election is conducted by the College of Cardinals. Once elected, the Pope serves as the leader of the Church, the Bishop of Rome, and oversees the Church’s leadership. The Pope also plays a pivotal role in formulating policy and pastoral decisions, appointing Church officials, and consolidating Catholic doctrine.

Bishops, Priests, and Deacons

Bishops, priests, and deacons fulfill multiple roles in the Church, including overseeing dioceses, parishes, and offering spiritual guidance to the faithful. Bishops supervise all diocesan offices and parishes, and act as the custodian of diocesan finances. Priests, on the other hand, are responsible for a specific geographic area known as a parish, and they administer the sacraments, preach the Gospel, and shepherd the faithful.

Deacons serve under the guidance of the bishop and represent the church within the community. They assist during Sunday Mass and perform other duties such as baptisms, weddings, and funerals.

The journey to becoming a bishop, priest, or deacon in the Catholic Church involves fulfilling various criteria, including being a practicing, baptized member of the Roman Catholic Church, meeting age and education requirements, and maintaining good standing with the Church.

Mary, Saints, and Angels

Mary, the mother of Jesus, along with saints and angels, are revered by Catholics as holy figures who can intercede for them. Recognized as the mother of Jesus, Mary is highly esteemed by Catholics as the sinless and ever-virgin mother, revered for her role in the narrative of salvation.

Saints, on the other hand, are individuals who have led exceptionally holy lives and are believed to dwell eternally with God in heaven. Catholics engage in the act of praying to saints, seeking their intercession with God.

Virgin Mary

Mary, revered as the mother of Jesus, occupies a unique position in the Catholic faith. She willingly yielded to the divine will, enabling the restoration of humanity’s communion with God. Mary’s participation in God’s design for our salvation is regarded as worthy of reverence. Her role is viewed as a vocation bestowed upon her by God since eternity.

In the Catholic understanding, Mary is referred to as the ‘Mother of God’ because of her being the mother of Jesus, who is believed to possess both human and divine nature. As Jesus is regarded as God, Mary is acknowledged as the mother of God. This title underscores the divinity of Jesus and the exceptional role that Mary had in the Incarnation.

Saints and Intercession

In the Catholic faith, saints are revered as paragons of holiness and virtue. They are men and women who have lived exemplary lives of faith and are believed to be in heaven. Catholics pray to saints, not as gods, but as fellow believers who can intercede for them before God.

Canonization is the process by which the Church declares a deceased person to be a saint. This process involves a thorough investigation of the person’s life and virtues, and the confirmation of miracles attributed to their intercession. The canonization process affirms that the person lived a life of heroic virtue and is in heaven, making them worthy of public veneration and capable of interceding for people on earth.

Catholic Moral Teachings

Guided by the Ten Commandments, the Catholic Church teaches a moral code and underscores the importance of social justice and care for the poor. The Ten Commandments, given by God to Moses on Mount Sinai, serve as a foundation for Catholic moral teachings, guiding believers in their relationship with God and others.

The early church also emphasizes social justice and care for the poor, following the example of Jesus and his teachings.

The Ten Commandments

Catholic moral teachings draw their foundation from the Ten Commandments. They provide guidance on how to love and worship God, and how to treat others with love and respect. By adhering to these commandments, Catholics aim to lead a life that is in harmony with God’s teachings and pleasing to Him.

These commandments, which include directives such as honoring one’s parents and not to bear false witness, serve as a moral compass for Catholics. They provide guidance on living a righteous and virtuous life, helping Catholics to maintain their relationship with God and their fellow human beings.

Social Justice and Care for the Poor

The call for social justice and care for the poor is extended to all Catholics. This call to love and serve the poor and marginalized is a fundamental part of the Catholic faith. The Church’s social teaching emphasizes the dignity of every human person and the need for a just society that respects and promotes human rights.

Catholics are encouraged to practice the corporal and spiritual works of mercy, such as feeding the hungry, sheltering the homeless, and visiting the sick. They are also called to advocate for social justice issues, such as peace, respect for human dignity, and care for creation. By doing this, they strive to bring the love and compassion of Christ to those in need.

The Afterlife and Final Judgment

The Catholic Church believes in life after death, where the soul undergoes God’s judgement and is sent to heaven, purgatory, or hell, depending on their deeds and relationship with God. This belief in the afterlife and final judgment is closely linked to the Catholic understanding of God’s justice and mercy, and the moral responsibility of each individual.


Heaven represents the eternal state of ultimate bliss and unity with God, promised to those who have conformed to God’s will. In heaven, the blessed will experience:

  • Eternal union with God through the beatific vision

  • Complete fulfillment and satisfaction

  • Perfect peace and joy

  • Freedom from all pain, suffering, and sin

  • Eternal life in the presence of God

This state of bliss and unity with the Lord thy God is both in the present and for all time.

Heaven is described as:

  • Eternal life with a loving God in supreme and definitive happiness

  • The ultimate fulfillment of human longings

  • A place where every tear will be wiped away, and death, mourning, crying, and pain will be no more

  • A state where the blessed will encounter peace, love, and the satisfaction of their longing for the infinite.

Purgatory and Hell

Purgatory serves as a sanctifying phase for souls that are not yet prepared for heaven. Souls in purgatory undergo a process of cleansing and purification to eliminate the temporal punishment due to forgiven sins before they can enter heaven. The Church teaches that through prayers, sacrifices, and the intercession of the Church, the souls in purgatory can be assisted in their purification.

Hell, on the other hand, is the eternal state of separation from God for those who die in a state of mortal sin and have not repented or sought God’s mercy. Hell is described as a real and literal place of complete alienation from everything that is good, hopeful, and loving in the world.

Catholic Worship and Prayer

Prayer and worship form the core of the Catholic faith. The Mass is the primary form of communal worship, where the faithful gather to celebrate the Eucharist and receive the body and blood of Christ. Prayer, both personal and communal, is an essential part of Catholic worship, and Catholics engage in various forms of prayer, including the Rosary, the Divine Office, and devotions to Mary and the saints.

The Mass

The Mass is the focal point of Catholic worship. It is a community gathering where the faithful come together to celebrate the Eucharist, which is the source and summit of the Christian life. The Mass is divided into four major parts:

  1. The Introductory Rites

  2. The Liturgy of the Word

  3. The Liturgy of the Eucharist

  4. The Concluding Rites

During the Mass, Catholics participate in the liturgical celebration of the life, death, and resurrection of Jesus Christ. They:

  • Listen to readings from Scripture

  • Reflect on the homily delivered by the priest

  • Profess their faith

  • Present their offerings

  • Receive Holy Communion

Personal and Communal Prayer

Beyond the Mass, Catholics participate in both personal and communal prayers. Personal prayer is seen as communion with God and allows individuals to express their thoughts, feelings, and desires to God, and to hear God’s voice in their hearts. Communal prayer, on the other hand, is an expression of the community’s faith and fellowship. This includes the Divine Office, or Liturgy of the Hours, which is the official set of prayers that mark the hours of each day.

Prayers like the Rosary, a meditative prayer on the mysteries of Christ’s life, are popular forms of personal and communal prayer. Devotions to Mary and the saints are also an important part of Catholic prayer life, where Catholics ask Mary and the saints to pray for them and to intercede with God on their behalf.


As we come to the end of our exploration into the Catholic faith, it is clear that Catholicism is a rich and profound tradition that encompasses a vast array of beliefs, practices, and moral teachings. From its core beliefs in the Holy Trinity and the life and teachings of Jesus Christ, to its reliance on Sacred Scripture and Tradition, the sacraments, the veneration of Mary and the saints, and the call to social justice and care for the poor, the Catholic faith provides a comprehensive guide for leading a life of faith, hope, and love.

Catholicism is not just a set of beliefs, but a way of life. It invites its adherents to enter into a personal relationship with God through Jesus Christ, to participate in the life of the Church community through the sacraments and liturgical worship, and to live out their faith in the world through acts of love, justice, and mercy. It calls Catholics to strive for holiness, to love God and neighbor, and to hope for eternal life in the presence of God.
