Heidelberg Catechism

Question 30. Do those also believe in the only Savior Jesus, who seek their salvation and welfare from “saints,” themselves, or anywhere else?

Answer. No; although they make their boast of Him, yet in their deeds they deny the only Savior Jesus;[1] for either Jesus is not a complete Savior, or they who by true faith receive this Savior, must have in Him all that is necessary to their salvation.[2]
