March 14, 2012 – Catechism 1391 – 1401

I do not know if I recall the Eucharist and getting rid of venial sins in this way. It makes a very rational argument for something that many may misunderstand. The Eucharist is Christ. When you come into communion with Christ (God), you are being separated from sin, because God cannot be a part of or have any connection to sin. Similar to Eve’s descendant having enmity with the serpent (argument for Mary being sinless). That connection we have with Christ in the Eucharist created enmity with sin and therefore separates us from our venial sins. This clears our conscious and allows us to avoid sin in the future in the same way that allowing venial sin to stay with us will lead eventually to mortal sin.

Mortal sin does not go away because that is our choice to turn away from God, not allowing that communion to take place, and putting enmity between us and God. God cannot cross that threshold without our choosing. As I explained before, our soul is dead when it is in mortal sin, and the Eucharist cannot feed a dead soul. Only the Sacrament of Reconciliation takes away that enmity so that we can commune with God once again.
