Apparently, this has been in the news for quite some time now, except that I only just now got wind of it. And getting wind of it is right: this stuff stinks.
The Presbyterian Church USA just recently voted to rename the Trinity to various other metaphors that they say allow them to seek "fresh ways to speak of the mystery of the triune God" and to "expand the church's vocabulary of praise and wonder."
Now, while I would agree with the notion that we need to seek "fresh ways to speak of the mystery of the triune God" and to "expand the church's vocabulary of praise and wonder," I do not believe that it is in any way justified in changing the way we address the Trinity. When Jesus taught us how to pray to God, He used the word Father. Similarly, when God Himself sent the Holy Spirit down to earth in the form of a dove, He said "This is my Son, in whom I am well pleased." If the Trinity addresses each other with Father, Son, and Holy Spirit, then I think that we should too. Just a thought. (Sources: 1, 2)
Still, let's backtrack a moment. While I can understand the arguments for wanting to present the feminine qualities of God, I think that the ultimate goal, and ultimate driving force behind the PCUSA's change to the Trinity comes the panel's opinion that the limiting of the Trinity to Father and Son "has been used to support the idea that God is male and that men are superior to women." In other words, there are several deeply wounded women who have been trampled on by men. Granted, some men have overstepped their bounds and behaved like raving lunatics, standing on an idea of man's innate superiority, while in fact this idea works as a shield for their own insecurities. Granted. Nevertheless, this is still not a good enough reason to go against Scripture.
Now, if denominational demographics are any indicator, I think we might be able to put a finger on why the PCUSA may have ended up voting the way they did. Women tend to seek comfort and relationship when coming to church, and one of the issues women find important includes the Family and raising children in the Church (Mother-Child-Womb fits nicely here, doesn't it?). Now, according to their own demographic material, 58.6% of their denomination is comprised of women and almost 70% of their deacons are women. While men clergy still outweigh the women 2 to 1, you have to ask yourself what men will see when they walk into one of these churches: a sea of women, talking about a Mother God, surrounded, perhaps, by a few men who apologize for the destruction their gender has done to women in the name of a masculine Trinity. Sensitive, self-effacing men, who, in the end, are unwilling to stand for the Scripture.
Not very appealing to a man, I can tell you that.
Which is why, perhaps, only 35% of men attend church regularly. Quite simply, because they find the church too effeminate.
Of course, this isn't just a PCUSA problem, but a nation-wide problem. In part, I believe, to the softening of the Gospel message. The more we put on the soft gloves to smack people with - if we even smack them at all - the more likely we are to push people away from Church - men in particular. Men are wired strangely. A man will follow another man who will knock him on his ass - both figuratively and literally - then help him up, and say, "Now, what can you learn from this pain?" and " Let me help you get stronger." A soft Gospel is no gospel at all, and if we look at the trends in US theology, we find that what is preached is nothing but a soft Gospel.
The Word of the Lord, however, is intended to be sharp, dividing bone from marrow, such that anyone who hears it should be cut with sword that brings healing.
