Ambrosiaster : Considering the love of Christ by which he loved us and gave himself up for us, we should make everything subject to him, knowing that he is the author of life for all. This is the truth. We are to be subject to him as members of the body are to the head. Others, either through error or through malice, may not confess that Christ is the head of everything or that everything is created from him by the Father's will. But we who adhere to the wholeness of faith ought nonetheless to take pains with all care and devotion that we bring no harm to this faith but rather to uphold it. We do this by remaining steadfast in this affirmation, so as to constrain the talk of depraved minds armed against the truth. — EPISTLE TO THE Ephesians 4.15 John Chrysostom : He expresses himself with great obscurity, from his desire to utter everything at once. What he means, however, is this. In the same way as the spirit, or vital principle, which descends from the brain, communicates the sensitive faculty which is conveyed through the nerves, not simply to all the members, but according to the proportion of each member, to that which is capable of receiving more, more, to that which is capable of less, less, (for the spirit is the root or source;) so also is Christ. For the souls of men being dependent upon Him as members, His provident care, and supply of the spiritual gifts according to a due proportion in the measure of every single member, effects their increase. But what is the meaning of this, "by the touch of the supply"? that is to say, by the sensitive faculty. For that spirit which is supplied to the members from the head, "touches," each single member, and thus actuates it. As though one should say, "the body receiving the supply according to the proportion of its several members, thus maketh the increase"; or, in other words, "the members receiving the supply according to the proportion of their proper measure, thus make increase"; or otherwise again thus, "the spirit flowing plenteously from above, and touching all the members, and supplying them as each is capable of receiving it, thus maketh increase." But wherefore doth he add, "in love"? Because in no other way is it possible for that Spirit to descend. For as, in case a hand should happen to be torn from the body, the spirit which proceeds from the brain seeks the limb, and if it finds it not, does not leap forth from the body, and fly about and go to the hand, but if it finds it not in its place, does not touch it; so also will it be here, if we be not bound together in love. All these expressions he uses as tending to humility. For what, he seems to say, if this or that man receives more than another? He has received the same Spirit, sent forth from the same Head, effectually working in all alike, communicating itself to all alike. "Fitly framed and knit together." That is, having great care bestowed upon it; for the body must not be put together anyhow, but with exceeding art and nicety, since if it gets out of place, it is no longer. So that each must not only be united to the body, but also occupy his proper place, since if thou shalt go beyond this, thou art not united to it, neither dost thou receive the Spirit. Dost thou not see, that in those dislocations of the bones which take place in any accident, when a bone gets out of its proper place and occupies that of another, how it injures the whole body, and oftentimes will produce death? So that sometimes it will be found to be no longer worth preserving. For many in many cases will cut it off, and leave a void in its place; because everywhere what is in excess is an evil. And so again with the elements, if they lose their proper proportion and be in excess, they impair the whole system. This is the meaning of the being "fitly framed and knit together." Consider then of how vast importance it is, that each should remain in his own proper place, and not encroach on another which in nowise appertains to him. Thou puttest the members together, He supplieth them from above. For as there are in the body such recipient organs, as we have seen, so is it also with the Spirit, the whole root or source being from above. For example, the heart is the recipient of the breath, the liver of the blood, the spleen of the bile, and the other organs, some of one thing, others of another, but all these have their source from the brain. So also hath God done, highly honoring man, and being unwilling to be far from him, He hath made Himself indeed the source of his dependence, and hath constituted them fellow-workers with Himself; and some He hath appointed to one office, and others to another. For example, the Apostle is the most vital vessel of the whole body, receiving everything from Him; so that He maketh eternal life to run through them to all, as through veins and arteries, I mean through their discourse. The Prophet foretells things to come, whilst He alone ordereth the same; Thou puttest the members together, but He supplies them with life, "For the perfecting of the saints, for the work of the ministry." Love builds up, and makes men cleave one to another, and be fastened and fitted together. — Homily on Ephesians 11 Philoxenus of Mabbug : And again in another speech Paul condemneth the heretics and sheweth that all their doctrine standeth in cunning. "Let us not be children, tossed to and fro and carried about with every wind of the deceitful doctrines of the children of men, who in their cunning act craftily to lead astray; but let us be firm in our love that we may make to grow up everything of ours in Christ." — 13 Ascetic Discourses, Discourse 4 -- On Faith: First Discourse on Simplicity Theodoret of Cyrus : This he also says in the letter to the Romans: "Let love be without pretense." In his letter to the Corinthians he speaks of "unpretending love." Here also he calls upon them to act with genuine love and through this to increase the riches of the excellence of their life in the Lord himself. — Interpretation of the Epistle to the Ephesians 4.15
