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"?
After conception, I would say that His life was very natural, in a physical sense. We know for sure that He sweated, bled, cried tears, thirsted, ate, etc. I have no reason to suppose He didn't have natural bodily functions either. Of course, if the terms are meant to be distinct from each other, His life was other than "usual". :)
