Heidelberg Catechism 23.61

Chapter 23 — Lord's Day 23

Section 61. Q. 61: Why do you say that by faith alone you are right with God? A. It is not because of any value my faith has that God is pleased with me. Only Christ's satisfaction, righteousness, and holiness make me right with God. And I can receive this righteousness and make it mine in no other way than by faith alone.
