Ephesians 5:30

“For we are members of his body, &c.] Not of his natural body, for this would make Christ's human nature monstrous; Christ, as man, is of our flesh and of our bones, or a partaker of the same flesh and blood with us; or otherwise, his incarnation would have been of no service to us; and had our human nature been from Christ, it would not have been corrupted; but our bodies, flesh, and bones, are from the first, and not the second Adam, and so corrupt and sinful; Christ indeed, as God, is the former of all human nature, and, as man, was set up in God's thoughts as the pattern of it; but the apostle is here speaking of the saints, not as men, but as Christians, as new creatures in Christ; and…”

“For--Greek, "Because" (Co1 6:15). Christ nourisheth and cherisheth the Church as being of one flesh with Him. Translate, "Because we are members of His body (His literal body), being OF His flesh and of His bones" [ALFORD] (Gen 2:23-24). The Greek expresses, "Being formed out of" or "of the substance of His flesh." Adam's deep sleep, wherein Eve was formed from out of his opened side, is an emblem of Christ's death, which was the birth of the Spouse, the Church. Joh 12:24; Joh 19:34-35, to which Eph 5:25-27 allude, as implying atonement by His blood, and sanctification by the "water," answering to that which flowed from His side (compare also Joh 7:38-39; Co1 6:11). As Adam gave Eve a new…”

“For we are members of his body - Of the body of Christ; see 1 Corinthians 11:3, note; 1 Corinthians 12:27, note; John 15:1-6, notes, and Ephesians 1:23, note. The idea here is, that there is a close and intimate union between the Christian and the Saviour - a union so intimate that they may be spoken of as “one”. Of his flesh, and of his bones - There is an allusion here evidently to the language which Adam used respecting Eve. “This is now bone of my bones, and flesh of my flesh;” Genesis 2:23. It is language which is employed to denote the closeness of the marriage relation, and which Paul applies to the connection between Christ and his people. Of course, it cannot be understood…”

“For we - The reason why Christ nourishes and cherishes the church is, that close connexion between them which is here expressed in the words of Moses, originally spoken concerning Eve. Are members - Are as intimately united to Christ, in a spiritual sense, as if we were literally "flesh of his flesh, and bone of his bone." Ephesians 5:31”
