Out of context, of couse. +Ignatius was confronting people who denied Christ's humanity.
That quote doesn't explain why was Mary's pregnancy supernatural and her labor wasn't.
This triumphalism reminds me somewhat of GW Bush's statement "we found WMDs" when the two weather ballon trucks were discovered by our troops in Iraq.
This was the main focus of that quote. It was about our Lord and His humanity.
Forest Keeper, would you say that Christ's life was "natural and usual"?
Mary's pregnancy was not supernatural, the conception of Jesus was. St. Ignatius' quote confirms that both the pregnancy and delivery were natural or normal. :
[Ignatius:] "... He was carried in the womb, even as we are, for the usual period of time; and was really born, as we also are ..."
It's no problem if you want to disagree with what he said, but the fact remains that he said it. :)
