Whether Christ's Ascension is the cause of our salvation?

Objections

Objection 1 : It would seem that Christ's Ascension is not the cause of our salvation. For, Christ was the cause of our salvation in so far as He merited it. But He merited nothing for us by His Ascension, because His Ascension belongs to the reward of His exaltation: and the same thing is not both merit and reward, just as neither are a road and its terminus the same. Therefore it seems that Christ's Ascension is not the cause of our salvation.
Objection 2 : Further, if Christ's Ascension be the cause of our salvation, it seems that this is principally due to the fact that His Ascension is the cause of ours. But this was bestowed upon us by His Passion, for it is written (Heb. 10:19): "We have [Vulg.: 'Having'] confidence in the entering into the holies by" His "blood." Therefore it seems that Christ's Ascension was not the cause of our salvation.
Objection 3 : Further, the salvation which Christ bestows is an everlasting one, according to Is. 51:6: "My salvation shall be for ever." But Christ did not ascend into heaven to remain there eternally; for it is written (Acts 1:11): "He shall so come as you have seen Him going, into heaven." Besides, we read of Him showing Himself to many holy people on earth after He went up to heaven. to Paul, for instance (Acts 9). Consequently, it seems that Christ's Ascension is not the cause of our salvation.
