To the position of fatherhood and motherhood God has given special distinction above all positions that are beneath it: He does not simply command us to love our parents, but to honor them. Regarding our brothers, sisters, and neighbors in general, He commands nothing more than that we love them (Matthew 22:39; 1 John 3:14). In this way He separates and distinguishes father and mother from all other persons upon earth and places them at His side. For it is a far higher thing to honor someone than to love someone, because honor includes not only love, but also modesty, humility, and submission to a majesty hidden in them. Honor requires not only that parents be addressed kindly and with reverence, but also that, both in the heart and with the body, we demonstrate that we value them very highly, and that, next to God, we regard them as the very highest. For someone we honor from the heart we must also truly regard as high and great. (Martin Luther, Large Catechism, Fourth Commandment).
All I can say is: “Wow.” What a great quote.
