Heidelberg Catechism – Lord’s Day 11
Q. Why is the Son of God called JESUS, which means SAVIOUR?
A. Because he saves us from our sins, and because salvation is to be sought or found in no other.
Q. Do those who seek their own salvation and well-being from saints, by their own efforts, or by other means really believe in the only Saviour Jesus?
A. No. Rather, by such actions they deny Jesus, the only Saviour and Redeemer, even though they boast of belonging to him. It therefore follows that either Jesus is not a perfect Saviour, or those who receive this Saviour with true faith must possess in him all that is necessary for their salvation.
