The Bible has no more to say about whether Mary’s hymen remained intact after Jesus’ birth or perpetual virginity than it did about the sun going around the earth. And the former theory is untestable.
The Bible says only:
Mat 1
24 Then Joseph being raised from sleep did as the angel of the Lord had bidden him, and took unto him his wife:
25 And knew her not till she had brought forth her firstborn son: and he called his name JESUS.
In fact, if the marriage was never consummated, that is grounds for the Cathlic Church to grant an annulment (i.e. there never was a marriage.)
But you did not answer my question. Nobody is attempting to add or delete anything from the Book of the Apocalypse. Therefore, your citation does not apply.
Do you have a citation that states that you should be silent where Scripture is silent?
The Bible says nothing about the impregnation either. Exactly what you do mean then by the Virgin Birth, except the negative that he had no human father?
