Dr. Luther’s Small Catechism lesson for the week of January 18, 2015:
[I] THE TEN COMMANDMENTS
IN THE PLAIN FORM IN WHICH THE HEAD OF THE FAMILY
SHALL TEACH IT TO HIS HOUSEHOLD
THE SIXTH COMMANDMENT
“You shall not commit adultery.”
What does this mean?
Answer: We should fear and love God, and so we should lead a chaste and pure life in word and deed, each one loving and honoring his wife or her husband.
