Q. 60: What is forbidden in the third commandment?
A. The third commandment forbids all profaning and abusing of anything whereby God makes Himself known.
If you will not hear, And if you will not take it to heart, to give glory to My name, Says the LORD of hosts, I will send a curse upon you, and I will curse your blessings. Yes, I have cursed them already, because you do not take it to heart. Malachi 2:2
