In C.S.Lewis’ article ‘Priestesses in the Church’, Lewis presents an argument where he picks an analogy of Church and uses it as an example of his opposition to women’s ministry. His analogy is the conversation in Pride and Prejudice:
“‘I should like Balls infinitely better,’ said Caroline Bingley, "if they were carried on in a different manner ... It would surely be much more rational if conversation instead of dancing made the order of the day."
‘Much more rational, I dare say,’ replied her brother, ‘but it would not be near so much like a Ball.’"
Lewis then argues that this argument translates to the situation in the church, that if women priests were allowed, it may be more rational but it wouldn't be near so much like a church any more.
A Ball by definition is about dancing, so if you remove the dancing it is no longer a Ball. The question is: what is the definition of a church, without which, it would not be church any more. I do not accept, as Lewis accepts, that church is defined by a man standing in front of the congregation, representing God to us. For me, a church is about God Himself, and the worship of Him by the whole congregation. It is that worship which, if removed, stops church from being church. Not the gender of the person presiding over the worship.
