Whether the attaining of glory is an effect of this sacrament?

Objections

Objection 1 : It seems that the attaining of glory is not an effect of this sacrament. For an effect is proportioned to its cause. But this sacrament belongs to "wayfarers" [viatoribus], and hence it is termed "Viaticum." Since, then, wayfarers are not yet capable of glory, it seems that this sacrament does not cause the attaining of glory.
Objection 2 : Further, given sufficient cause, the effect follows. But many take this sacrament who will never come to glory, as Augustine declares (De Civ. Dei xxi). Consequently, this sacrament is not the cause of attaining unto glory.
Objection 3 : Further, the greater is not brought about by the lesser, for nothing acts outside its species. But it is the lesser thing to receive Christ under a strange species, which happens in this sacrament, than to enjoy Him in His own species, which belongs to glory. Therefore this sacrament does not cause the attaining of glory.
