The biblical accounts of Jesus' ministry include: his baptism, miracles, preaching, teaching and deeds. Jesus' death and resurrection are commemorated by Christians in all worship services, with special emphasis during Holy Week which includes Good Friday and Easter Sunday.The death and resurrection of Jesus are usually considered the most important events in Christian theology, partly because they demonstrate that Jesus has power over life and death and therefore has the authority and power to give people eternal life.
The Athanasian Creed, received in the Western Church as having the same status as the Nicene and Chalcedonian, says: "We worship one God in Trinity, and Trinity in Unity; neither confounding the Persons nor dividing the Substance." The central tenet of Christianity is the belief in Jesus as the Son of God and the Messiah (Christ).Worldwide, the four largest branches of Christianity are the Catholic Church, Protestantism, the Eastern Orthodox Church, and Oriental Orthodoxy.The Catholic, Eastern Orthodox and Oriental Orthodox churches broke communion with each other in the East–West Schism of 1054, and the Chalcedonian schism in 451.The creeds further maintain that Jesus physically ascended into heaven, where he reigns with God the Father in the unity of the Holy Spirit, and that he will return to judge the living and the dead and grant eternal life to his followers.His incarnation, earthly ministry, crucifixion and resurrection are often referred to as "the gospel", meaning "good news".Christians believe that Jesus, as the Messiah, was anointed by God as savior of humanity and hold that Jesus' coming was the fulfillment of messianic prophecies of the Old Testament.
The Christian concept of the Messiah differs significantly from the contemporary Jewish concept.
The term gospel also refers to written accounts of Jesus' life and teaching, four of which—Matthew, Mark, Luke, and John—are considered canonical and included in the Christian Bible, as established by the 5th century for the ancient undivided Catholic and Eastern Orthodox traditions, a period sometimes referred to as the Great Church, before the East–West Schism in 1054.
Throughout the history of Christianity, theological and ecclesiological disputes have resulted in schisms with many distinct denominations.
This particular creed was developed between the 2nd and 9th centuries.
Its central doctrines are those of the Trinity and God the Creator.
Christian theology is summarized in creeds such as the Apostles' Creed and the Nicene Creed.
