The head has under its authority very many members, some of which are corrupt and weak. So also our Lord, being the Head of the Church, has as His members all those who are united in the Church, both saints and sinners. The saints are subject to Him voluntarily, but sinners by necessity.
"And He put all things under His feet, and gave Him as Head over all things to the Church, which is His Body, the fullness of Him who fills all in all." This seems to contradict what is written elsewhere: "For He must reign until He has put all His enemies under His feet" (1 Cor 15:25). For if all things are not yet subject to Him, and He must reign until all things are subjected to Him, how has God put all things under His feet? This is especially so when Paul himself testifies elsewhere: "When all things are subjected to Him, then the Son Himself will also be subjected to Him who subjected all things to Him, that God may be all in all" (1 Cor 15:28).
From the comparison of these passages, ergo, it follows either that, by foreknowledge of the future, the Apostle speaks of it as already accomplished. This is like his earlier statement: "He blessed us with every spiritual blessing in the heavenly places in Christ." Or perhaps, if this can be referred to the past, we should understand it thus. Even what is not voluntarily subject to Him serves Him by the force of its nature, such as demons, Jews, and Gentiles. Indeed, they do not serve Christ and are not subject under His feet. Yet because they were created in bonam partem, for a good purpose, they are unwillingly subject to His power, though by free will they resist Him.
The following words also fit this meaning: "and gave Him as Head over all things to the Church, which is His Body." For as the head has under its authority very many members. Many of them diseased and weak, so our Lord, being Head of the Church, has as His members all those who are united in the Church, both saints and sinners. The saints are subject to Him voluntarily, but sinners by necessity. In this way even His enemies are subjected under His feet.
For this reason, the word all seems to contain a question. The words, "Sit at My right hand until I make Thy enemies a footstool for Thy feet" (Ps 109:1), and elsewhere, "He must reign until He has put all His enemies under His feet" (1 Cor 15:25), hardly need interpretation. What is hostile to Him, when conquered, will be subjected under His feet and will pass under the authority of the Victor.
Thus one may answer that nothing is without sin. Even the stars are not pure before the face of God, and all creation trembles at the coming of the Lord (Job 15). Therefore it is affirmed that the Cross of the Savior purified not only what is on earth, but also what was in heaven.
Another interpreter refers the word all not to the universe, but only to the matter under discussion. This is like the expression, "The whole city cried out." It is said as though no one in the city had been silent, though the minority is indicated through the greater part who were shouting. Paul himself says, "All seek their own, not the things of God" (Phil 2:21), and, "All forsook me" (2 Tim 4:16). This does not mean that Timothy and the other disciples with him when he wrote the epistle abandoned him. It means that he was abandoned by the majority, that is, by all in the sense of the greater part.
The Psalter suggests a similar meaning: "They have all turned aside; together they have become unprofitable. There is none who does good, no, not one" (Ps 13:3). For if all turned aside, then the one who speaks also turned aside. And elsewhere: "I said in my haste, Every man is a liar" (Ps 115:2).
But what is said is either true or false. If every man is a liar, then the speaker is a liar. Thus his assertion that every man is a liar is not true. But if his assertion is true, then the word every must be understood in the sense indicated above. It means that the majority of men speak falsely.
The words "the fullness of Him who fills all in all" must likewise be understood in accord with the well-known words: "When all things are subjected to Him, then the Son Himself will also be subjected to Him who subjected all things to Him, that God may be all in all" (1 Cor 15:28). For at present God is in men only in part. In one He is present as righteousness, in another as purity, in a third as continence. In one He is present as wisdom, in another as strength. It is difficult even for holy and perfect men to possess all virtues equally. But when, at the end of present things and at the end of the world, all things are subjected to Him, then all things will be fulfilled in all. All will possess everything that individual persons previously possessed separately.
Moreover, his words, "and gave Him as Head over all things to the Church, which is His Body, the fullness of Him who fills all in all," can be understood not only in relation to the Church of men, but also to angels, all powers, and rational creatures.
Likewise, the words "the fullness of Him who fills all in all" must by no means be understood merely as they sound. Rather, he has said: He who is fulfilled by all in all. To fill and to be fulfilled mean different things. In the first, the one acting is indicated. In the second, the one acted upon is indicated.
As a general is increased when his armies are increased, when new forces appear, and when the number of the people grows, so our Lord Jesus Christ Himself is fulfilled in all. This is insofar as all believe in Him and daily come to faith in Him. Yet He is fulfilled with all in all, that is, those who believe in Him are filled with all virtues. According to the word of the Gospel, they allow Him Himself to advance in age, wisdom, and grace, not only before God but also before men (Lk 7:50).
