St. Norbert, archbishop of Magdeburg, in North Germany, was the founder of the Canons Regular or Premonstratensians, as they were called. The doctrine of the Real Presence having been questioned by Tanchelin of Antwerp, our saint, who was distinguished for his devotion to the Blessed Sacrament, reclaimed many who had fallen away, and rekindled the love of Our Lord in the Blessed Eucharist.

The chief characteristic of the mission of St. Norbert was his eloquent preaching of the word of God. This is an entirely apostolic mission which is not always appreciated as much as it should be. The preaching of the Gospel is indeed a most necessary thing, for no man can believe the Word of God and be saved except there be an apostle to preach it to him. He died in 1134, worn out with toil.
