To which “god” is he referring?
The one that says such behavior is an abomination, the product of a depraved mind, judgement on those who reject knowledge of Him?
Probably not THAT “God”, but some other.
RE: To which god is he referring?
In Ancient Greece, the Twins Castor and Pollux, were the gods of Homosexuality.
a mortal named Leda was seduced by Zeus who came to her in the form of a swan. Leda gave birth to an egg from which emerged Castor, Pollux and Helen (yes, eventually of Troy).
The identical brothers were inseparable, and had a deep affection for one another, for which reason they were often worshipped as gods of homosexuality (afterall, they were sons of Zeus).
Helen, a great beauty, was constantly being abducted and in need of rescue, which the brothers were usually successful in accomplishing, however, her beauty was eventually to lead to the Trojan War.
Castor was a skilled horseman, and Pollux was an unconquerable boxer. They took part in the voyage of the Argonauts, and with Orpheus they calmed a storm, for which reason they were also worshipped as the protectors of sailors.
