29 But, perhaps, in their misguided and impious perversity, they infer His weakness from the fact that His soul was sorrowful unto death. It is not yet the time to blame you, heretic, for misunderstanding the passage. For the present I will only ask you, Why do you forget that when Judas went forth to betray Him, He said, Now is the Son of Man glorified ? If suffering was to glorify Him, how could the fear of it have made Him sorrowful? How, unless He was so void of reason, that He feared to suffer when suffering was to glorify Him?
