"It (Eucharist) was instituted not for satisfaction, but for nourishing spiritually through union between Christ and His members, as nourishment is united with the person nourished. But because this union is the effect of charity, from the fervor of which man obtains forgiveness, not only of guilt but also of punishment, hence it is that [...]
"The reality of this sacrament is charity, not only as to its habit, but also as to its act, which is kindled in this sacrament; and by this means venial sins are forgiven. Consequently, it is manifest that venial sins are forgiven by the power of this sacrament." Source: St. Thomas Aquinas, Summa Theologica [...]
"The parable of the Good Samaritan remains as a standard which imposes universal love towards the needy whom we encounter 'by chance' (cf. Lk 10:31), whoever they may be… Anyone who needs me, and whom I can help, is my neighbor. The concept of 'neighbor' is now universalized, yet it remains concrete. Despite being extended to all [...]
"Practice, then, charity always and in all things, for the occasions are numberless. If they do not come to you, seek them.

Source: St. Catherine [...]

"What, then, are the characteristics of fraternal charity? The same as those of Our Lord's love for us. First, Our Lord loved us for ourselves, and not for Himself. Love that loves others for self, is only egoism. We must, then, love our brethren for their spiritual good, and even for their temporal good according [...]
" Abide with God that you may learn His kindness. Abide in recollection with yourselves that you may discover your own misery and learn how to despise yourselves. These are the two sources of fraternal charity, and the secret of love for the brethren. Fraternal charity is the well-beloved virtue of Our Lord. It is [...]
"Humility makes us receptive to giving of others. You could not give unless I took. It is the taker that makes the giver." Source: Ven. Fulton J. Sheen, Way to Happiness, St. Pauls, 1998.
