I don't understand something, what exactly is your argument against gay marriage?

How is using the for natural? That is for excrement ONLY! And eating shellfish etc. was under the law, Old Testament. Does not apply to grace age believers. God says it is an abomination to Him. People who do such things will have no part in the Kingdom of God. Go ahead and live ever how you choose, but don't even try to justify it. Not to me.
