No. You can't know that because Luke never mentions Mary being a PERPETUAL virgin..... he in fact says NOTHING about Mary at the moment of her death (or undeath - depending on what Catholic teacher you are docilicly submitting to); good reason: his Gospel Book was likely penned before Mary died (or didn't). Friend, honestly, if you have a verse in Luke that stated Mary was a PERPETUAL virgin, you would have quoted it. We all know that. Come on, my friend.....
Yes, EVENTUALLY..... years too late for anyone to get this normally very, very, very private, personal tidbit of marriage bed info from Mary or Joseph..... YES, some CLAIMED (with nothing, nothing, absolutely NOTHING WHATSOEVER to show it as true) that Mary DID or she did NOT have sex after Jesus was born... both speculations were voiced. And yes, you are right my friend, EVENTUALLY - centuries later than Mary could have confirmed or denied such or given her permission to to go on so about this normally very private, personal matter - there came to be a consensus that She remained a virgin. Yup. But that's unrelated to what Scripture says or does not say..... unrelated to early tradition (which was silence)..... even unrelated as to whether it's true. Your apologetic would be accurate if you said, "In the SEVENTH CENTURY, an Ecumenical Council used the TITLE "Ever Virgin." That would be correct, and for many of us - important. The rest of what you are posting is incredibly weak and embarrassingly bad apologetics. No offense intended, my friend, but...... this kind of HORRIBLE, LAUGHABLE apologetics is why a lot of Protestants think so little of Catholicism (you are making matters worse, my friend).
