Whether a bishop alone confers the sacrament of Order?

Objections

Objection 1 : It would seem that not only a bishop confers the sacrament of Order. For the imposition of hands has something to do with the consecration. Now not only the bishop but also the assisting priests lay hands on the priests who are being ordained. Therefore not only a bishop confers the sacrament of Order.
Objection 2 : Further, a man receives the power of Order, when that which pertains to the act of his Order is handed to him. Now the cruet with water, bowl* and towel, are given to the subdeacon by the archdeacon; as also the candlestick with candle, and the empty cruet to the acolyte. [*"Bacili." The rubric has "aquamanili." Some texts of the Summa have "mantili" ("maniple"), but the archdeacon does not give the maniple to the subdeacon.] Therefore not only the bishop confers the sacrament of Order.
Objection 3 : Further, that which belongs to an Order cannot be entrusted to one who has not the Order. Now the conferring of minor Orders is entrusted to certain persons who are not bishops, for instance to Cardinal priests. Therefore the conferring of Orders does not belong to the episcopal Order.
Objection 4 : Further, whoever is entrusted with the principal is entrusted with the accessory also. Now the sacrament of Order is directed to the Eucharist, as accessory to principal. Since then a priest consecrates the Eucharist, he can also confer Orders.
Objection 5 : Further, there is a greater distinction between a priest and a deacon than between bishop and bishop. But a bishop can consecrate a bishop. Therefore a priest can ordain a deacon.
