Christianity

Overview: Christianity is a religious tradition that arose within the Jewish environment of the first century and is centered on Jesus of Nazareth, whom Christians recognize as the Christ, that is, the promised messiah and the decisive figure in human salvation. Over the course of history, Christianity developed multiple traditions, churches, and theological schools, but it preserves a common core tied to faith in God, the centrality of Jesus, the authority of the Christian Scriptures, and hope in the resurrection and final judgment.

Origin and development: The religion emerged from the preaching of Jesus and the witness of his disciples, especially after the paschal experience of the resurrection. It spread through the Roman Empire and later through much of the world, taking on diverse cultural, liturgical, and institutional forms. Its major historical branches include Catholicism, Eastern Orthodoxy, Oriental Orthodox churches, Protestantism, and many later movements.

Central beliefs: In its historically predominant form, Christianity affirms one God, the unique importance of Jesus Christ, his death and resurrection, the action of the Holy Spirit, the normative value of the Bible, the need for redemption, baptism, the communal life of the Church, and the hope of eternal life. Not all of these beliefs receive the same formulation in every denomination, and some nontrinitarian Christian groups diverge from classical conciliar formulations.

Texts and authority: The New Testament and the Old Testament make up the Christian Bible, although the canon varies in some branches. Authority is structured in different ways: some traditions emphasize councils, apostolic succession, and magisterium, while others prioritize biblical reading, confessions of faith, and local or congregational autonomy. This variety helps explain disagreements over sacraments, ministry, veneration of saints, justification, and church structure.

Comparison and debates: Christianity shares with other Abrahamic religions themes such as creation, prophecy, morality, and judgment, but it offers distinctive formulations about Jesus, incarnation, the cross, and resurrection. Among the most important internal debates are the nature of the Church, the relationship between faith and works, Christ's presence in the Lord's Supper, ministerial authority, interpretation of Scripture, the role of tradition, and contemporary diversity among confessions.
