Whether the sound of the trumpet will be the cause of our resurrection?

Objections

Objection 1 : It would seem that the sound of the trumpet will not be the cause of our resurrection. For the Damascene says (De Fide Orth. iv): "Thou must believe that the resurrection will take place by God's will, power, and nod." Therefore since these are a sufficient cause of our resurrection, we ought not to assign the sound of the trumpet as a cause thereof.
Objection 2 : Further, it is useless to make sounds to one who cannot hear. But the dead will not have hearing. Therefore it is unfitting to make a sound to arouse them.
Objection 3 : Further, if any sound is the cause of the resurrection, this will only be by a power given by God to the sound: wherefore a gloss on Ps. 67:34, "He will give to His voice the voice of power," says: "to arouse our bodies." Now from the moment that a power is given to a thing, though it be given miraculously, the act that ensues is natural, as instanced in the man born blind who, after being restored to sight, saw naturally. Therefore if a sound be the cause of resurrection, the resurrection would be natural: which is false.
