My challenge to self-identified Christians who support same-sex marriage:
1. Establish what your basis of moral authority is.
2. If it is the Bible, develop a biblical case for same sex marriage.
3. Identify the moral reasoning you are employing.
4. Put your argument in premise-conclusion form.
5. Rebut the major objections to your position.
6. Explain why your view was never held in the history of the church or endorsed by any religion or civilization until recent decades.
