Anthanasius had access to no more scripture than is available today...He may be a champion of your religion but your religion is not the champion of millions upon millions of people...
There are no doubt many bible teachers whom I respect who also agree with Anthanasius in some or even much of what he says...But he is not my champion...My champion is Jesus Christ...And outside of Jesus Christ, there is no champion of his church...
Preach it, brother.
