Familial relations in Ephesians

The passage falls within the HKCEE RS examination syllabus on family life --- husband and wife, parents and children, master and slaves. Therefore, it is a very familiar piece of text.
There were very few Old Testament quotations in this epistle to the Ephesians. But in the discussion of these big issues, Paul would be very uncomfortable to talk about them without quoting the Scripture. Here the texts are nearly identical with the Septuagint.
Here is the text about marriage:
ἀντὶ τούτου καταλείψει ἄνθρωπος [τὸν] πατέρα καὶ [τὴν] μητέρα καὶ προσκολληθήσεται πρὸς τὴν γυναῖκα αὐτοῦ, καὶ ἔσονται οἱ δύο εἰς σάρκα μίαν. (Ephesians 5:31)
ἕνεκεν τούτου καταλείψει ἄνθρωπος τὸν πατέρα αὐτοῦ καὶ τὴν μητέρα αὐτοῦ καὶ προσκολληθήσεται πρὸς τὴν γυναῖκα αὐτοῦ, καὶ ἔσονται οἱ δύο εἰς σάρκα μίαν. (Genesis 2:24)
Compared with 1 Corinthians, Paul's moral theology on marriage in the Ephesians is more palatable. In 1 Corinthians, his rhetoric is very negative and offensive. His ideal way of life was to remain single so that he might pay undivided attention to serve the Lord.
It is well for a man not to touch a woman.
But because of the temptation to immorality, each man should have his own wife and each woman her own husband (1 Corinthians 7:1b-2).
But if they (the unmarried and the widows) cannot exercise self-control, they should marry. For it is better to marry than to be aflame with passion (1 Corinthians 7:9).
I want you to be free from anxieties. The unmarried man is anxious about the affairs of the Lord, how to please the Lord;
but the married man is anxious about worldly affairs, how to please his wife,
and his interests are divided (1 Corinthians 7:32-34a).
In the Ephesians, Paul demonstrated a more mature approach. After discussing the moral theology of marriage in the language of love, the talk on the marriage between man and his wife is finally sublimated into the sacred marriage between Christ and the Church! When you expect the prooftext to be quoted against divorce, Paul sublimated it to talk about the Mystical Body of Christ!
Next comes the Commandment to honour parents:
τίμα τὸν πατέρα σου καὶ τὴν μητέρα, ... ,
ἵνα εὖ σοι γένηται καὶ ἔσῃ μακροχρόνιος ἐπὶ τῆς γῆς. (Ephesians 6:2-3)
τίμα τὸν πατέρα σου καὶ τὴν μητέρα, ἵνα εὖ σοι γένηται, καὶ ἵνα μακροχρόνιος γένῃ ἐπὶ τῆς γῆς ... (Exodus 20:12)
Here, Paul gave a more balanced interpretation of the Commandment to honour parents. Besides urging children to obey parents, he also urged parents to treat their children, most likely adults, on a more nearly equal footing.
Fathers, do not provoke your children to anger, but bring them up in the discipline and instruction of the Lord (Ephesians 6:4).
Therefore, parents do not simply feed their children. The spiritual well-being of children should also concern them. Fair enough. From here, the Church extends the application of this Commandment to a government and her subjects. While the citizens should obey the government, the government in turn should also take care of the well-being, physical as well as spiritual, of them.
From here, Paul touched on the relation with slaves who were an integral part of the institution of family in ancient time. Of course, nowadays we find slavery offensive to our sensitivity. However offensive we feel about it, the teaching of Paul still applies today.
Masters, do the same to them (the slaves, the subordinates), and forbear threatening, knowing that he who is both their Master and yours is in heaven, and that there is no partiality with him (Ephesians 6:9).
However much I may dislike my bosses, it is a consolation to know that we are all subordinates of the same Master in heaven.

My dear Master, teach me to be humble and forbearing; complain less and work more. I pray for Joseph. Master, help him through. Amen.
