So, then, which of the Commandments aren't you supposed to follow?
“We are under the command to love, which doesn’t allow murder, etc”
You just validated the entire Christian homosexual lobby. They aren’t hurting anyone. They’re just ‘loving’.
Incidentally, there is only one commandment in the religion of Wicca - “Do what thou will, but harm none.”
So if there are no rules for Christians except to ‘love’ then you’ve just proved the new-age Christians totally valid and there is no longer a moral or Biblical argument against gay marriage.
