Whether this sacrament benefit others besides the recipients?

Objections

Objection 1 : It seems that this sacrament benefits only the recipients. For this sacrament is of the same genus as the other sacraments, being one of those into which that genus is divided. But the other sacraments only benefit the recipients; thus the baptized person alone receives effect of Baptism. Therefore, neither does this sacrament benefit others than the recipients.
Objection 2 : Further, the effects of this sacrament are the attainment of grace and glory, and the forgiveness of sin, at least of venial sin. If therefore this sacrament were to produce its effects in others besides the recipients, a man might happen to acquire grace and glory and forgiveness of sin without doing or receiving anything himself, through another receiving or offering this sacrament.
Objection 3 : Further, when the cause is multiplied, the effect is likewise multiplied. If therefore this sacrament benefit others besides the recipients, it would follow that it benefits a man more if he receive this sacrament through many hosts being consecrated in one mass, whereas this is not the Church's custom: for instance, that many receive communion for the salvation of one individual. Consequently, it does not seem that this sacrament benefits anyone but the recipient.
