One poster in particular claimed that had Mary not remained a virgin after the birth of Jesus, he would have been no better than Heracles.
It was post 884. I think it was phrased a bit elliptically, but the last thing it does is argue that the Perpetual Virginity caused the Divinity of Christ -- quite the opposite. And classical references can be more startling than enlightening in a post-first or -second century world!
