Same sex marriage and the Church

The Anglican Church is in trouble over the issue of Same Sex Marriage (SSM). A report by the House of Bishops was brought before the General Synod for approval in terms of being 'noted'. The paper, which broadly approved the idea of the Church conducting SSMs was voted on on by the house of Clergy and the house of Laity, requiring approval from all sections to gain approval. It failed, meaning that it could be years before the issue is considered again, leaving all parties in a state of unsatisfactory limbo.
The problem is one of scripture. Although the bible doesn't mention 'marriage' Genesis tells us that God gave Adam a wife so that thereafter a  man would leave his parents and 'become one flesh' with a woman, in his case, Eve. So it is said God ordained the institution of marriage.
On one side of the argument opponents of the move say that scripture, time and again, reviles against same sex relationships whilst others say that the God of love cannot harden his heart against loving couples of any hue. Those against argue that marriage should be for a man and woman who wish to bear children naturally whilst those for the proposition say that same sex couples can adopt. There are also irrelevant issues of 'human rights' abounding.
As I say in the conclusion of my book: 'Spiritual Man: An Introduction to Negative Dimensions', should Churches abandon all notion of a supernatural, creator God and instead embrace the spirituality of man under the banner of: Do unto others as you would have them do unto you. With God out of the way the door opens for love, hope, compassion and charity to flood in.
