"Communion with the Body and Blood of Christ increases the communicant's union with the Lord, forgives his venial sins, and preserves him from grave sins. Since receiving this sacrament strengthens the bonds of charity between the communicant and Christ, it also reinforces the unity of the Church as the Mystical Body of Christ." Source: [...]
"The washing of the hands is done in the celebration of mass out of reverence for this sacrament; and this for two reasons: first, because we are not wont to handle precious objects except the hands be washed; hence it seems indecent for anyone to approach so great a sacrament with hands that are, even [...]
"While it is not a hard thing to abstain from murder, but it is very difficult to avoid all passing fits of anger, which assail us at every moment.

"Holy Communion separates us from sin. The body of Christ we receive in Holy Communion is 'given up for us,' and the blood we drink 'shed for the many for the forgiveness of sins.' For this reason the Eucharist cannot unite us to Christ without at the same time cleansing us from past sins and [...]
"The conclusion of all this is that you be ready to die rather than commit a mortal sin, and ready to die, also, rather than commit a venial sin with deliberation. Rather endure all things, rather death itself than offend God! It would be better to let the whole world go to ruin rather than [...]
