The Sixth Commandment

​The Heidelberg Catechism: Lord's Day 40

105. Q. What does God require in the sixth commandment?

A. I am not to dishonor, hate, injure, or kill my neighbor by thoughts, words, or gestures, and much less by deeds, whether personally or through another;[1] rather, I am to put away all desire of revenge.[2] Moreover, I am not to harm or recklessly endanger myself.[3] Therefore, also, the government bears the sword to prevent murder.[4]

[1] Gen. 9:6; Lev. 19:17, 18; Matt. 5:21, 22; 26:52. [2] Prov. 25:21, 22; Matt. 18:35; Rom. 12:19; Eph. 4:26. [3] Matt. 4:7; 26:52; Rom. 13:11-14. [4] Gen. 9:6; Ex. 21:14; Rom. 13:4.

106. Q. But does this commandment speak only of killing?

A. By forbidding murder God teaches us that He hates the root of murder, such as envy, hatred, anger, and desire of revenge,[1] and that He regards all these as murder.[2]

[1] Prov. 14:30; Rom. 1:29; 12:19; Gal. 5:19-21; James 1:20; I John 2:9-11. [2] I John 3:15.

107. Q. Is it enough, then, that we do not kill our neighbor in any such way?

A. No. When God condemns envy, hatred, and anger, He commands us to love our neighbor as ourselves,[1] to show patience, peace, gentleness, mercy, and friendliness toward him,[2] to protect him from harm as much as we can, and to do good even to our enemies.[3]

[1] Matt. 7:12; 22:39; Rom. 12:10. [2] Matt. 5:5; Luke 6:36; Rom. 12:10, 18; Gal. 6:1, 2; Eph. 4:2; Col. 3:12; I Pet. 3:8. [3] Ex. 23:4, 5; Matt. 5:44, 45; Rom. 12:20.
