Whether Christ died out of obedience?

Objections

Objection 1 : It would seem that Christ did not die out of obedience. For obedience is referred to a command. But we do not read that Christ was commanded to suffer. Therefore He did not suffer out of obedience.
Objection 2 : Further, a man is said to do from obedience what he does from necessity of precept. But Christ did not suffer necessarily, but voluntarily. Therefore He did not suffer out of obedience.
Objection 3 : Further, charity is a more excellent virtue than obedience. But we read that Christ suffered out of charity, according to Eph. 5:2: "Walk in love, as Christ also has loved us, and delivered Himself up for us." Therefore Christ's Passion ought to be ascribed rather to charity than to obedience.
