Despite all the evidence Mary still purports to retain her virginity, at least for the time being. The trick is done by tampering with the original texts, retaining known errors of translation, inserting suitable confirmatory material into sacred texts, rejecting the plain meaning of words in favour of contrived meanings, and glossing over contradictions and inconsistencies. All this is an open secret. No Church scholar of any standing denies it. But then none openly advertises it either, so the faithful masses remain in ignorance.
