Whether several priests can consecrate one and the same host?

Objections

Objection 1 : It seems that several priests cannot consecrate one and the same host. For it was said above (Question [67], Article [6]), that several cannot at the same time baptize one individual. But the power of a priest consecrating is not less than that of a man baptizing. Therefore, several priests cannot consecrate one host at the same time.
Objection 2 : Further, what can be done by one, is superfluously done by several. But there ought to be nothing superfluous in the sacraments. Since, then, one is sufficient for consecrating, it seems that several cannot consecrate one host.
Objection 3 : Further, as Augustine says (Tract. xxvi in Joan.), this is "the sacrament of unity." But multitude seems to be opposed to unity. Therefore it seems inconsistent with the sacrament for several priests to consecrate the same host.
