Wednesday, Third Week of Lent: "that you may live"

whoever obeys and teaches these commandments will be called greatest in the Kingdom of heaven

--Mt 5:17-19

It is in the Church, in communion with all the baptized, that the Christian fulfills his vocation. From the Church he receives the Word of God containing the teachings of "the law of Christ." From the Church he receives the grace of the sacraments that sustains him on the "way." From the Church he learns the example of holiness and recognizes its model and source in the all-holy Virgin Mary; he discerns it in the authentic witness of those who live it; he discovers it in the spiritual tradition and long history of the saints who have gone before him and whom the liturgy celebrates in the rhythms of the sanctoral cycle.

Wednesday, Lent Wk 3: "Do not think that I have come to abolish the law"

I have come not to abolish but to fulfill

-- Mt 5:17-19

Jesus, Israel's Messiah and therefore the greatest in the kingdom of heaven, was to fulfill the Law by keeping it in its all embracing detail - according to his own words, down to "the least of these commandments". He is in fact the only one who could keep it perfectly. On their own admission the Jews were never able to observe the Law in its entirety without violating the least of its precepts. This is why every year on the Day of Atonement the children of Israel ask God's forgiveness for their transgressions of the Law. The Law indeed makes up one inseparable whole, and St. James recalls, "Whoever keeps the whole law but fails in one point has become guilty of all of it."
