Timeline
Death and Resurrection of Jesus (as claimed)
**c. 30 CE** — According to the Christian tradition (including Roman Catholicism), Jesus of Nazareth was crucified and rose from the dead, events that believers regard as the decisive revelation of God's saving action. Historians situate Jesus' ministry in the early first century in Roman Judea and study the New Testament and other ancient sources to reconstruct aspects of his life and its aftermath.
Pauline Missionary Activity and Epistles
**c. 50–60 CE** — The missionary journeys and letters of Paul of Tarsus contributed to the spread of Christianity across the Mediterranean and to the formation of theological reflection on Christ, law, and community. Pauline epistles such as Romans and Corinthians remain foundational textual witnesses in Catholic theology and liturgy.
Edict of Milan (Legal Toleration of Christianity)
**313** — The Edict of Milan, associated with Constantine and Licinius, granted religious toleration to Christians within the Roman Empire, altering the legal status and public life of Christian communities. Scholars highlight the long-term institutional consequences of imperial support for Christianity.
First Council of Nicaea
**325** — Convened by Constantine, the Council of Nicaea sought to address Arian controversies and produced the original form of the Nicene Creed articulating the Son’s relationship to the Father. The council’s decisions had enduring theological and ecclesiastical consequences throughout Christendom.
Edict of Thessalonica (Christianity as Imperial Religion)
**380** — The Edict issued by Emperor Theodosius I declared Nicene Christianity the official religion of the Roman Empire, a shift that historians see as central to the church’s evolving relationship with political power and administrative structures.
Council of Chalcedon
**451** — The Council of Chalcedon formulated doctrines concerning the person of Christ (the Chalcedonian Definition) that became normative in the Western and much of the Eastern church, while also contributing to later ecclesial divisions with non-Chalcedonian communities.
East–West Schism (Mutual Excommunications)
**1054** — The mutual excommunications between representatives of Rome and Constantinople in 1054 are commonly dated in histories as a pivotal event in the formal division between Western (Latin) and Eastern (Greek) Christian communions, though historians emphasize a long process of growing divergence before and after that date.
Council of Trent
**1545–1563** — The Council of Trent was a major Catholic response to Protestant reform, clarifying doctrines such as justification, the sacraments, and the canon of Scripture, and instituting reforms in clerical education and discipline; it shaped Catholic identity into the modern era.
Foundation of the Society of Jesus (Jesuits)
**1540** — Pope Paul III approved the constitutions of the Society of Jesus, an order founded by Ignatius of Loyola; the Jesuits became influential in education, missionary activity, and the Catholic Reformation.
First Vatican Council
**1869–1870** — The First Vatican Council addressed issues of modernity and authority, defining the doctrine of papal infallibility under specific conditions and articulating the role of the pope in doctrinal teaching.
Second Vatican Council (Vatican II)
**1962–1965** — Vatican II produced a set of documents (e.g., Sacrosanctum Concilium, Dei Verbum, Gaudium et Spes) that reoriented liturgical practice, emphasized the role of the laity, and initiated a new posture toward the modern world and interreligious dialogue.
Promulgation of the Code of Canon Law (1983)
**1983** — The 1983 Code of Canon Law updated and codified ecclesiastical law in the postconciliar era, providing juridical norms for sacramental practice, clerical discipline, and the governance of dioceses and religious institutes.
