With respect, that's evasion. Saying teachings "fall short of the mark" only means they can be improved and developed as the Church learns and grows; not that they are untrue. Yes, we see through a mirror darkly and God's mysteries are ultimately beyond the human mind. But we do have Divine revelation. How else would be begin to understand the Incarnation and the Triune God? However, this acknowledgement of humility before God is not the same as suggesting existing doctrine "contradict faith and reason."
