What is required in the third commandment?
That we, not only by cursing or perjury, but also by rash swearing, must not profane or abuse the name of God; nor by silence or connivance be partakers of these horrible sins in others; and, briefly, that we use the holy name of God no otherwise than with fear and reverence, so that He may be rightly confessed and worshipped by us, and be glorified in all our words and works.
