The 4th Commandment is, "You are to honor your father and mother."
Again, in reading from Luther's Large Catechism some of the detailed description and teaching caught my attention so I am sharing here a section of it to ponder.
This is from, "The Book of Concord" translated by Kolb and Wengert. It can be found on p.400-1 of the print edition on The First Commandment from the Large Catechism section.
So far we have learned the first three commandments, which are directed toward God. First, we are to trust, fear, and love God with our whole heart all our lives. Second, we should not misuse his holy name to support lies or any evil purpose whatsoever, but use it for the praise of God and the benefit and salvation of our neighbor and ourselves. Third, on holy days or days of rest we should diligently devote ourselves to God‘s Word so that all our conduct and life may be regulated by it. Now follow the other seven, which relate to our neighbor. Among these the first and greatest is:
"You are to honor your father and mother."
God has given this walk of life, fatherhood and motherhood, a special position of honor, higher than that of any other walk of life under it. Not only has he commanded us to love parents but to honor them. In regard to brothers, sisters, and neighbors in general he commands nothing higher than that we love them. But he distinguishes father and mother above all other persons on earth, and places them next to himself. For it is a much higher thing to honor than to love. Honor includes not only love, but also deference, humility, and modesty directed (so to speak) toward a majesty concealed within them. Honor requires us not only to address them affectionately and with high esteem, but above all to show by our actions, both of heart and body, that we respect them very highly, and that next to God we give them the very highest place. For anyone whom we are wholeheartedly to honor, we must truly regard as high and great.
It must therefore be impressed on young people that they revere their parents as God‘s representatives, and to remember that, however lowly, poor, feeble, and eccentric they may be, they are still their mother and father, given by God. They are not to be deprived of their honor because of their ways or failings. Therefore, we are not to think of their persons, whatever they may be, but of the will of God, who has created and ordained it so. We are indeed all equal in God‘s sight, but among ourselves it is impossible for there not be this sort of inequality and proper distinction. Therefore God also commands that you are to obey me as your father and that I have authority over you.
First, then, learn what this commandment requires concerning honor to parents. You are to esteem them above all things and to value them as the most precious treasure on earth. Second, in your words you are also to behave respectfully toward them and are not to speak discourteously to them, to criticize them, or to take them to task, but rather to submit to them and hold your tongue, even if they go too far. Third, you are also to honor them by your actions, that is, with your body and possessions, serving them, helping them, and caring for them when they are old, sick, feeble, or poor; all this you should do not only cheerfully, but also with humility and reverence, doing it as if for God. Those who know how they are to cherish their parents in their hearts will not let them endure want or hunger, but will place them above and beside themselves and share with them all they have to the best of their ability.
