The Heidelberg Catechism Part II: Deliverance God the Son, Part 1 Lord’s Day 11
Question 29: Why is the Son of God called “Jesus,” meaning “savior”?
Answer 29: Because He saves us from our sins,  and because salvation should not be sought and cannot be found in anyone else.

Q 30: Do those who look for their salvation in saints, in themselves, or elsewhere really believe in the only savior Jesus?
A 30: No. Although they boast of being His, by their actions they deny the only savior, Jesus.  Either Jesus is not a perfect savior, or those who in true faith accept this savior have in him all they need for their salvation. 
 1 Corinthians 1:12-13 NKJV Now I say this, that each of you says, "I am of Paul," or "I am of Apollos," or "I am of Cephas," or "I am of Christ." (13) Is Christ divided? Was Paul crucified for you? Or were you baptized in the name of Paul?
Galatians 5:4 NKJV You have become estranged from Christ, you who attempt to be justified by law; you have fallen from grace.
