Unfortunately, it seems that the homosexual heresy may be as persistent as the Arian heresy, which lasted for nearly three centuries. It persisted even after Nicea supposedly settled the matter with a definition that Jesus was of the same substance as the Father.
Athanasius, the great defender of Christological orthodoxy, kept getting exiled by one emperor or another because he was considered too rigid and divisive and unwilling to compromise. He would not agree to reconcile with the Arians because although they accepted the language of Nicea, they interpreted it to mean something different–Christ was not fully God.
The mass of people remained fully Catholic but the elites and ruling classes held on to Arianism as a distinctive. Ultimately Catholic orthodoxy carried the day. If not, we would have had an entirely different religion–as we will if the Church were to succumb to the current heresy.
