Q.66: What is forbidden in the fourth commandment?
A. The fourth commandment forbids the omission or careless performance of the duties required, and the profaning the day by idleness, or doing that which is in itself sinful, or by unnecessary thoughts, words, or works, about worldly employments or recreations.
Moreover they have done this to Me: They have defiled My sanctuary on the same day and profaned My Sabbaths. Ezekiel 23:38
