Quote from Luther’s Large Catechism:
“We must, therefore, impress this truth upon the young [Deuteronomy 6:7] that they should think of their parents as standing in God’s place. They should remember that however lowly, poor, frail, and strange their parents may be, nevertheless, they are the father and the mother given to them by God. Parents are not to be deprived of their honor because of their conduct or their failings.”
Besides the supremacy of upholding the will of God, it also really makes a difference in our own lives to seek to honor our parents!
