We human beings are social beings. We come into the world as the result of others’ actions. We survive here in dependence on others. Whether we like it or not, there is hardly a moment of our lives when we do not benefit from others’ activities. For this reason, it is hardly surprising that most of our happiness arises in the context of our relationships with others.
When we cast our bread upon the waters we can presume that someone downstream whose face we will never know will benefit from our action, as we who are downstream from another will profit from the grantor's gift.
Consequently, heretics and schismatics, separated from the unity of this Body, are able to receive the same Sacrament, but with no benefit to themselves; indeed, more to their own harm, in that they are judged the more severely rather than being liberated.
There is in general good reason to suppose that in several respects the gods could all benefit from instruction by us human beings. We humans are - more humane.
We must not stint
Our necessary actions in the fear
To cope malicious censurers, which ever,
As rav'nous fishes, do a vessel follow
That is new-trimmed, but benefit no further
Than vainly longing.
