The Lord's Supper cures and brings life to both body and soul...

Here [the Lord's Supper] He offers to us the entire treasure that He has brought for us from heaven.  With the greatest kindness He invites us to receive it also in other places, like when He says in St. Matthew 11:38, "Come to Me, all who labor and are heavy laden, and I will give you rest."  It is surely a sin and a shame that He so cordially and faithfully summons and encourages us to receive our highest and greatest good, yet we act so distantly toward it.  We permit so long a time to pass without partaking of the Sacrament that we grow quiet cold and hardened, so that we have no longing or love for it.  We must never think of the Sacrament as something harmful from which we had better flee, but as a pure, wholesome, comforting remedy that grants salvation and comfort.  It will cure you and give you life both in soul and body.  For where the soul has recovered, the body is also relieved.
