Q. 71 What is required in the seventh commandment? A. The seventh commandment requireth the preservation of our own and our neighbour's chastity in heart, speech, and behaviour. Q. 72 What is forbidden in the seventh commandment? A. The seventh commandment forbiddeth all unchaste thoughts, words, and actions. Last week, we focused on the importance of preserving our own and our neighbour's chastity by avoiding anything that breaks marriage apart. Today, I want to preach to you about one of the greatest plagues upon our society—what I am going to call soul-shrinking lust. When sex is longed for and even worse, engaged in, outside of marriage, it shrivels up your soul in such a way that you treat other people more like objects than persons.

WSC Q71-72-c: The Place of Sex in Marriage

The idea of imparting a body of truth (rudiments of the faith) is found repeatedly in scripture under many different terms and descriptions. We are not given a complete catechism or confession in the Bible. That is because we are to write our own according to the needs of the day. They must refute new heresies as they arise. Our Lord has called us to catechise in His church… to teach disciples the basics of the faith. Make the most of this instruction: memorise your Catechism, listen to the messages, and pray for the Spirit to work.
