The Westminster Larger Catechism

Q.119. What particular sins does the fourth commandment forbid?

A. The fourth commandment forbids failing to do anything required by the commandment;[1] or doing it carelessly, negligently, or in such a way as not to benefit from it, and being tired of keeping it;[2] also treating the day as unholy by loafing, by doing anything in itself sinful,[3] and by all useless works, words, and thoughts about our worldly affairs and recreations.[4]
