Father Longenecker (former Church of England Priest, now Catholic Priest) has written some very sad pieces recently on his blog regarding Same Sex Marriage and the Church of England.
Anglicans Prepare for Same Sex Weddings
I see no reason why anybody should be anything but clear minded about which way this debate will go. The Church of England decided long long ago that homosexual marriage was permissible. As they did in every debate since the Reformation, the Anglican bishops will hum and haw wondering if their dear old Church of England is more “Church” or more “England” and in the end they will decide that it is more “England” than “Church”. That is because conformity to the state and adaptation to the spirit of the age is written into the genetic code of the Church of England. The Elizabethan Settlement was just that–a settlement by the Queen of England. It settled things. It said essentially, “You may do whatever you like in church and believe whatever you like as long as you do as I say in things that matter to me.”
Another Elizabeth is on the throne now, but the same settlement holds true. Members of the Church of England are free to believe whatever they want and do whatever they want, as long as they conform to the current laws of England, the prevailing mores and the contemporary culture.
