Whether Order is a sacrament?

Objections

Objection 1 : It would seem that Order is not a sacrament. For a sacrament, according to Hugh of St. Victor (De Sacram. i) "is a material element." Now Order denotes nothing of the kind, but rather relation or power; since Order is a part of power according to Isidore. Therefore it is not a sacrament.
Objection 2 : Further, the sacraments do not concern the Church triumphant. Yet Order is there, as in the angels. Therefore it is not a sacrament.
Objection 3 : Further, just as spiritual authority, which is Order, is given by means of consecration, so is secular authority, since kings also are anointed, as stated above (Question [19], Article [3], ad 2). But the kingly power is not a sacrament. Therefore neither is order of which we speak now.
