How do non-Trinitarians determine their biblical canon? I've often heard from non-Trinitarians that Constantine marks the point when the Church was corrupted, as he presided over the Council of Nicaea which made Trinitarianism orthodox. The biblical canon was set officially at later councils than Nicaea, which would be the corrupt Church in the non-Trinitarian view, so where do non-Trinitarians get their canon from?
