Whether original sin would be contracted by a person formed miraculously from human flesh?

Objections

Objection 1 : It would seem that original sin would be contracted by a person formed miraculously from human flesh. For a gloss on Gn. 4:1 says that "Adam's entire posterity was corrupted in his loins, because they were not severed from him in the place of life, before he sinned, but in the place of exile after he had sinned." But if a man were to be formed in the aforesaid manner, his flesh would be severed in the place of exile. Therefore it would contract original sin.
Objection 2 : Further, original sin is caused in us by the soul being infected through the flesh. But man's flesh is entirely corrupted. Therefore a man's soul would contract the infection of original sin, from whatever part of the flesh it was formed.
Objection 3 : Further, original sin comes upon all from our first parent, in so far as we were all in him when he sinned. But those who might be formed out of human flesh, would have been in Adam. Therefore they would contract original sin.
