What are we to make of people who don't want other people to have the same rights and legal privileges as they enjoy,its weird how they cherry pick and change their positions over time if it is truly a belief, like slavery,pork or the role of women or how children are now people instead of property they too will change their position on this issue in the future acting as if their opposition never even happened.
I think as a Christan you would focus on things christ had said and not things he did not after all hes supposed to be the son of god,by the way gay marriage is older then Christianity.
