Heidelberg Catechism on Justification

60. Q. How are you righteous before God?

A. Only by true faith in Jesus Christ.[1] Although my conscience accuses me that I have grievously sinned against all God's commandments, have never kept any of them,[2] and am still inclined to all evil,[3] yet God, without any merit of my own,[4] out of mere grace,[5] imputes to me the perfect satisfaction, righteousness, and holiness of Christ.[6] He grants these to me as if I had never had nor committed any sin, and as if I myself had accomplished all the obedience which Christ has rendered for me,[7] if only I accept this gift with a believing heart.[8]

[1] Rom. 3:21-28; Gal. 2:16; Eph. 2:8, 9; Phil. 3:8-11. [2] Rom. 3:9, 10. [3] Rom. 7:23. [4] Deut. 9:6; Ezek. 36:22; Tit. 3:4, 5. [5] Rom. 3:24; Eph. 2:8. [6] Rom. 4:3-5; II Cor. 5:17-19; I John 2:1, 2. [7] Rom. 4:24, 25; II Cor. 5:21. [8] John 3:18; Acts 16:30, 31; Rom. 3:22.

61. Q. Why do you say that you are righteous only by faith?

A. Not that I am acceptable to God on account of the worthiness of my faith, for only the satisfaction, righteousness, and holiness of Christ is my righteousness before God.[1] I can receive this righteousness and make it mine my own by faith only.[2]

[1] I Cor. 1:30, 31; 2:2. [2] Rom. 10:10; I John 5:10-12.

62. Q. But why can our good works not be our righteousness before God, or at least a part of it?

A. Because the righteousness which can stand before God's judgment must be absolutely perfect and in complete agreement with the law of God,[1] whereas even our best works in this life are all imperfect and defiled with sin.[2]

[1] Deut. 27:26; Gal. 3:10. [2] Is. 64:6.

63. Q. But do our good works earn nothing, even though God promises to reward them in this life and the next?

A. This reward is not earned[1]; it is a gift of grace.[2]

[1] Matt. 5:12; Heb. 11:6. [2] Luke 17:10; II Tim. 4:7, 8.
