Q. 53. What is the third commandment?
A. The third commandment is, Thou shalt not take the name of the Lord thy God in vain; for the Lord will not hold him guiltless that taketh his name in vain.

1. Does the third commandment concern the manner of our worshipping God? Yes: That we serve the Lord with fear, Ps. 2:11. Is it enough that we seek God in a due ordinance? No: but we must seek him after the due order, 1 Chron. 15:13.

2. Is God's name all that whereby he makes himself known? Yes: He proclaimed the name of the Lord, Exod. 34:5. Ought we to make use of his name? Yes: By thee only will we make mention of thy name, Isa. 26:13. And to take heed of abusing it? Yes: Neither shalt thou profane the name of thy God, I am the Lord, Lev. 18:21.
