But I would have you know. — After the general commendation in the previous verse, the reproof for neglecting, or desiring to neglect, his precepts in one particular case, is thus introduced. The subject treated of, viz., the uncovering of their heads by women in assemblies for worship, was of ephemeral moment, and as we all now would regard it, of trivial importance. Every circumstance, however, which could in the least degree cause the principles of Christianity to be perverted or misunderstood by the heathen world was of vital importance in those early days of the Church, and hence we find the Apostle, who most fearlessly taught the principles of Christian liberty, condemning most earnestly every application of those principles which might be detrimental to the best interests of the Christian faith. To feel bound to assert your liberty in every detail of social and political life is to cease to be free — the very liberty becomes a bondage.
The head of every man is Christ. — The Apostle does not merely treat of the outward practice on which his advice has been sought, but proceeds to lay down the principles which are opposed to the principle of that absolute and essential equality, which, found its expression and assertion in the practice of women uncovering their heads in public assemblies.
The allusion here is not to Christ as the Head of the whole human race and of all things (as in Ephesians 1:22; Colossians 1:16; Colossians 2:10), but as the Head of “the Body,” the Christian Church: and this thought introduces the general argument regarding the practical subordination of woman, by reminding the Corinthians that though there is in the Church a perfect spiritual equality (as taught in Galatians 3:28), yet that it is an equality which is of order and not of disorder — that it is an equality which can only be preserved by remembering that each is not an isolated irresponsible atom, but a part of an organic whole. There is a Head to the Church, therefore it is not a machine composed of various parts, but a body consisting of various members. As there is a subordination of the whole body to Christ, so there is in that body a subordination of woman to man. The last clause, “the Head of Christ is God,” gives (as is St. Paul’s custom, see 1 Corinthians 3:23; 1 Corinthians 8:6; 1 Corinthians 15:25) completeness to the thought. As the Head of the Church — i.e., as the man Christ Jesus — Christ is subordinate to the Father, and, indeed, perhaps the idea is carried farther into the mystery of the divine nature itself, as consisting of three Persons co-eternal and co-equal, yet being designated with an unvarying sequence as “first,” and “second,” and “third.”
