Christianity and Roman Catholics both came from the Teachings of Paul. It started in Antioch and yet Christians call Catholics the Anti-Christ.
Catholics don't worship idols. They have icons.
Christians worship the idols Paul taught them to. God's son is Yahshua Messiah. Paul changed it to Jesus Christ.
I (Paul) verily thought with myself, that I ought to do many things contrary to the name of Jesus of Nazareth.
And he changed it.
Christians worship Jesus. Yahshua clearly taught to worship God the Father.
