From C. S. Lewis’ essay against priestesses in church - a couple of the best paragraphs he ever wrote:
 
“It is painful, being a man, to have to assert the privilege, or the burden, which Christianity lays upon my own sex. I am crushingly aware how inadequate most of us are, in our actual and historical individualities, to fill the place prepared for us. But it is an old saying in the army that you salute the uniform not the wearer. Only one wearing the masculine uniform can (provisionally, and till the Parousia) represent the Lord to the Church: for we are all, corporately and individually, feminine to Him. We men may often make very bad priests. That is because we are insufficiently masculine. It is no cure to call in those who are not masculine at all. A given man may make a very bad husband; you cannot mend matters by trying to reverse the roles. He may make a bad male partner in a dance. The cure for that is that men should more diligently attend dancing classes; not that the ballroom should henceforward ignore distinctions of sex and treat all dancers as neuter. That would, of course, be eminently sensible, civilized, and enlightened, but, once more, "not near so much like a Ball".
And this parallel between the Church and the Ball is not so fanciful as some would think. The Church ought to be more like a Ball than it is like a factory or a political party. Or, to speak more strictly, they are at the circumference and the Church at the Centre and the Ball comes in between. The factory and the political party are artificial creations - "a breath can make them as a breath has made". In them we are not dealing with human beings in their concrete entirety only with "hands" or voters. I am not of course using "artificial" in any derogatory sense. Such artifices are necessary: but because they are our artifices we are free to shuffle, scrap and experiment as we please. But the Ball exists to stylize something which is natural and which concerns human beings in their entirety-namely, courtship. We cannot shuffle or tamper so much. With the Church, we are farther in: for there we are dealing with male and female not merely as facts of nature but as the live and awful shadows of realities utterly beyond our control and largely beyond our direct knowledge. Or rather, we are not dealing with them but (as we shall soon learn if we meddle) they are dealing with us.”
 
Lewis' essay has a few flaws, but if you want to read the whole thing (which I highly recommend), go here.
