What Makes Someone a Christian?

In the early centuries, most Christian leaders agreed on a handful of central documents that expressed the core of their faith. These are called creeds, and they include most importantly the Apostles' Creed and the Nicene Creed. The creeds declared that Jesus was the Son of God who, being born of a virgin, lived a human life that culminated in a short ministry of teaching, miraculous healings, and finally crucifixion. Creeds are often recited during worship services as a way of affirming the faith.
