I place this in the category: we have no way to know for sure, especially when based upon how the words are translated. I once told a person, who was adamant on this topic: I’ll have to ask Jesus when I get to heaven.
For others, when I’m in a sarcastic mood, I say: This is one of the top ten things I’ll go back in time to find out, if Doctor Who ever picks me as a companion.
My personal bottom line is that Mary’s perpetual virginity is not what I hang my faith in her Son and his message of salvation upon.
Likewise, indeed. I have no need to elevate Mary.
