20 Children, obey your parents in all things: for this is well pleasing unto the Lord.
[AD 407] John Chrysostom on Colossians 3:18-25
"Wives, be in subjection to your husbands, as is fitting in the Lord. Husbands, love your wives, and be not bitter against them. Children, obey your parents in all things, for this is well-pleasing in the Lord. Fathers, provoke not your children, that they be not discouraged. Servants, obey in all things them that are your masters according to the flesh; not with eyeservice, as menpleasers, but in singleness of heart, fearing the Lord: whatsoever ye do, work heartily, as unto the Lord, and not unto men; knowing that from the Lord you shall receive the recompense of the inheritance: ye serve the Lord Christ. For he that does wrong shall receive again for the wrong that he has done: and there is no respect of persons with God. [Colossians 4:1] Masters, render unto your servants that which is just and equal; knowing that you also have a Master in heaven."

Why does he not give these commands everywhere, and in all the Epistles, but only here, and in that to the Ephesians, and that to Timothy, and that to Titus? Because probably there were dissensions in these cities; or probably they were correct in other respects, so that it was expedient they should hear about these things. Rather, however, what he says to these, he says to all. Now in these things also this Epistle bears great resemblance to that to the Ephesians, either because it was not fitting to write about these things to men now at peace, who needed to be instructed in high doctrines as yet lacking to them, or because that for persons who had been comforted under trials, it were superfluous to hear on these subjects. So that I conjecture, that in this place the Church was now well-grounded, and that these things are said as in finishing.

[AD 386] Cyril of Jerusalem on Colossians 3:20
But while honoring our heavenly Father, let us also honor the “fathers of our flesh,” since the Lord in the Law and the Prophets has clearly laid this down, saying: “Honor your mother and your father, that it may be well with you, and that you may have a long life in the land.” Let those present who have mothers and fathers pay attention to this command. “Children, obey your parents in all things, for this is pleasing to the Lord.” For our Lord did not say: “He who loves father or mother is not worthy of me,” else what was well written you might interpret falsely out of ignorance, but he added “more than me.”
[AD 407] John Chrysostom on Colossians 3:20
Ver. 20. "Children, obey your parents in all things, for this is well-pleasing in the Lord."

Again he has put that, "in the Lord," at once laying down the laws of obedience, and shaming them, and casting them down. For this, says he, is well-pleasing to the Lord. See how he would have us do all not from nature only, but, prior to this, from what is pleasing to God, that we may also have reward.

[AD 407] John Chrysostom on Colossians 3:20
Again Paul has written, “in the Lord,” at once laying down the laws of obedience, producing shame in them. For this, he says, is wellpleasing to the Lord. See how Paul would have us live not only according to natural principles but, prior to this, according to what is pleasing to God. In this way we also gain a reward.
