After reading both sides of the issue, to me it is inconclusive and imo really matters very little. I have to ask myself, What is the objective here? Is it to determine whether the Christian church system once accepted same sex marriages? If so, it then raises the further questions in me, Should the church system be our guide on these issues? Do we follow men. a system, or the light that God has put within us?
The real question to me regardless of purported writings perhaps is....Are we the judge of our brother that does to us no harm? Does any of us have an inside track of the will of God for another? Is it not enough for each of us to establish our own path? Should a sense of fairness and justice prevail in our civil laws and system? Considering those questions, though it may be an interesting study in history to research such an issue, it seems to me establishing whether those rites existed as reported or not should have little bearing on what direction we take as a society.
Just my own view for consideration,
Joseph
