X.

Argument:  Every man is corrupted by original sin and has concupiscence. 

Christ had neither concupiscence nor original sin.  Therefore he is not a

man.

Response:  I make a distinction with regard to the major premise.  Every man

is corrupted by original sin, with the exception of Christ.  Every man who is

not a divine Person [personaliter Deus], as is Christ, has concupiscence, but

the man Christ has none, because he is a divine Person, and in conception the

flesh and blood of Mary were entirely purged, so that nothing of sin

remained.  Therefore Isaiah says rightly, "There was no guile found in his

mouth"; otherwise, every seed except for Mary's was corrupted.
