Efésios 5

28 Just so the husbands ought to love their own wives as their own bodies; he who loves his wife loves himself. 29 After all, no one ever hated his own flesh; rather he nourishes and cherishes it, just as the Lord does the Church 30 —for we are members of His body, of His flesh and of His bones.*Less than 2.5% of the Greek manuscripts, of objectively inferior quality, omit "of His flesh and of His bones" (as in NIV, NASB, LB, TEV, etc.—an easy case of ‘similar ending’). Flesh and bones are definitely physical, not spiritual; so what is Paul saying? Perhaps he is emphasizing that "His body" is just as real as a physical body. 31 "For this reason a man shall leave his father and mother and be joined to his wife, and the two will become one flesh."*This is not just poetic language, it is a chemical reality. See Genesis 2:24. 32 This is a great mystery, but I speak concerning Christ and the Church.

33 In any case, each of you individually: let each one love his own wife as himself,*Observe that ‘wife’ is singular. Although in the Old Testament men were not condemned for having more than one wife, in the context of the Church monogamy is the norm. The instruction in verse 33 is basic: if a wife does not feel loved and/or a husband does not feel respected, negative things start to happen. while the wife must respect her husband.
