Christianity’s public life in Acts begins at Pentecost, when the disciples in Jerusalem are filled with the Holy Spirit and speak to Jews from many nations. The disciples were called Christians first in Antioch. Jesus is the one they confess. The Council of Nicaea in 325 states the faith. It does not create the church.

Who Founded It

The church in Acts preaches Jesus crucified and raised. The Resurrection of Jesus What Is the Deity of Christ? The Trinity is the confession of one God, Father, Son, and Holy Spirit.

Did Paul Invent Christianity? answers the claim that Paul created a different religion from Jesus.

Nicaea Is Not the Start
