Whether Christ was of necessity subject to these defects?

Objections

Objection 1 : It would seem that Christ was not of necessity subject to these defects. For it is written (Is. 53:7): "He was offered because it was His own will"; and the prophet is speaking of the offering of the Passion. But will is opposed to necessity. Therefore Christ was not of necessity subject to bodily defects.
Objection 2 : Further, Damascene says (De Fide Orth. iii, 20): "Nothing obligatory is seen in Christ: all is voluntary." Now what is voluntary is not necessary. Therefore these defects were not of necessity in Christ.
Objection 3 : Further, necessity is induced by something more powerful. But no creature is more powerful than the soul of Christ, to which it pertained to preserve its own body. Therefore these defects were not of necessity in Christ.
