Whether corporal almsdeeds have a spiritual effect?

Objections

Objection 1 : It would seem that corporal almsdeeds have not a spiritual effect. For no effect exceeds its cause. But spiritual goods exceed corporal goods. Therefore corporal almsdeeds have no spiritual effect.
Objection 2 : Further, the sin of simony consists in giving the corporal for the spiritual, and it is to be utterly avoided. Therefore one ought not to give alms in order to receive a spiritual effect.
Objection 3 : Further, to multiply the cause is to multiply the effect. If therefore corporal almsdeeds cause a spiritual effect, the greater the alms, the greater the spiritual profit, which is contrary to what we read (Lk. 21:3) of the widow who cast two brass mites into the treasury, and in Our Lord's own words "cast in more than . . . all." Therefore bodily almsdeeds have no spiritual effect.
