Another explanation I heard was that straight pastors were not permitted to have sex outside the confines of marriage, and since gay marriage was not legal at the time, gay clergy members could not have sex. This was an especially dumb explanation. The marriage that was illegal was a matter of state government and had nothing to do with a covenant with God. It’s like saying God doesn’t want you to baptize someone because you don’t have a city permit to install a hot tub.
