Dr. Luther’s Small Catechism lesson for the week of December 18, 2016:
[I] THE TEN COMMANDMENTS
IN THE PLAIN FORM IN WHICH THE HEAD OF THE FAMILY
SHALL TEACH IT TO HIS HOUSEHOLD
“You shall not take the name of the Lord your God in vain.”
What does this mean?
Answer: We should fear and love God, and so we should not use his name to curse, swear, practice magic, lie, or deceive, but in every time of need call upon him, pray to him, praise him, and give him thanks.
