Whatever this is, it is not Christianity, which affirms that God has spoken to us in Jesus Christ. C.S. Lewis, in an essay on women’s ordination in Anglicanism, put the matter thus:
But Christians think that God himself has taught us how to speak of him. To say that it does not matter is to say either that all the masculine imagery is not inspired, is merely human in origin, or else that, though inspired, it is quite arbitrary and unessential. And this is surely intolerable: or, if tolerable, it is an argument not in favor of Christian priestesses but against Christianity.
Cardinal Ratzinger made a similar point in The Ratzinger Report: “Christianity is not a philosophical speculation; it is not a construction of our mind. Christianity is not ‘our’ work; it is a Revelation; it is a message that has been consigned to us, and we have no right to reconstruct it as we like or choose. Consequently, we are not authorized to change the Our Father into an Our Mother: the symbolism employed by Jesus is irreversible; it is based on the same Man-God relationship he came to reveal to us.”
Now people are certainly free to reject Christianity. But they should be honest enough to admit that this is what they are doing, instead of surreptitiously replacing Christianity with the milk of the Goddess, in the name of putting new wine into old wineskins.
Those who insist on substituting their own language for the supposed “sexism” of the Gospel (and therefore of God, since Scripture was inspired by Him) are really just displaying their own arrogance and faith in themselves, rather than faith in God. After all, if the “sexism” of God needs to be corrected, what other teachings of His can be tossed?
Read the whole thing (both parts) to see why it makes no sense given the nature of masculinity and femininity (and from the nature of creation) to consider God as Mother.
