~Third Commandment

Question 99. What is required in the third Commandment?

Answer. That we must not by cursing,[1] or by false swearing,[2] nor yet by unnecessary oaths,[3] profane or abuse the name of God; nor even by our silence[4] and connivance be partakers of these horrible sins in others; and in summary, that we use the holy name of God in no other way than with fear and reverence,[5] so that He may be rightly confessed[6] and worshiped[7] by us, and be glorified in all our words and works.[8]
