Whether the form of this sacrament is suitably expressed?

Objections

Objection 1 : It would seem that the form of this sacrament is unsuitably set forth in the text (Sent. iv, D, 24). Because the sacraments take their efficacy from their form. Now the efficacy of the sacraments is from the divine power, which works our salvation in them in a most hidden manner. Therefore the form of this sacrament should include a mention of the divine power by the invocation of the Trinity, as in the other sacraments.
Objection 2 : Further, to command pertains to one who has authority. Now the dispenser of the sacrament exercises no authority, but only ministry. Therefore he should not use the imperative mood by saying: "Do" or "Receive" this or that, or some similar expression.
Objection 3 : Further, mention should not be made in the sacramental form, except of such things as are essential to the sacrament. But the use of the power received is not essential to this sacrament, but is consequent upon it. Therefore it should not be mentioned in the form of this sacrament.
Objection 4 : Further, all the sacraments direct us to an eternal reward. But the forms of the other sacraments make no mention of a reward. Therefore neither should any mention be made thereof in the form of this sacrament, as in the words: "Since thou wilt have a share, if faithfully," etc.
