Whether it is proper to Christ to be Head of the Church?

Objections

Objection 1 : It seems that it is not proper to Christ to be Head of the Church. For it is written (1 Kgs. 15:17): "When thou wast a little one in thy own eyes, wast thou not made the head of the tribes of Israel?" Now there is but one Church in the New and the Old Testament. Therefore it seems that with equal reason any other man than Christ might be head of the Church.
Objection 2 : Further, Christ is called Head of the Church from His bestowing grace on the Church's members. But it belongs to others also to grant grace to others, according to Eph. 4:29: "Let no evil speech proceed from your mouth; but that which is good to the edification of faith, that it may administer grace to the hearers." Therefore it seems to belong also to others than Christ to be head of the Church.
Objection 3 : Further, Christ by His ruling over the Church is not only called "Head," but also "Shepherd" and "Foundation." Now Christ did not retain for Himself alone the name of Shepherd, according to 1 Pt. 5:4, "And when the prince of pastors shall appear, you shall receive a never-fading crown of glory"; nor the name of Foundation, according to Apoc. 21:14: "And the wall of the city had twelve foundations." Therefore it seems that He did not retain the name of Head for Himself alone.
