Saint Albert the Great Quote

“Do this in remembrance of me.” Two things should be noted here. The first is the command that we should use this sacrament, which is indicated when Jesus says, “Do this.” The second is that this sacrament commemorates the Lord’s going to death for our sake. This sacrament is profitable because it grants remission of sins; it is most useful because it bestows the fullness of grace on us in this life. “The Father of spirits instructs us in what is useful for our sanctification.” And his sanctification is in Christ’s sacrifice, that is, when he offers himself in this sacrament to the Father for our redemption to us for our use. Christ could not have commanded anything more beneficial, for this sacrament is the fruit of the tree of life.

-- Saint Albert the Great from a commentary on the Gospel of Luke
