Brother, Do Y ou See What I See
During his stay at the new abbey which he had established at Floreffe, when he (St. Norbert) was saying Mass, he noticed upon the paten just before communion a large drop of the Precious Blood, all red and surrounded by rays of light … He turned to his deacon and said, “Brother, do you see what I see?” “I do, Father,” he replied. The altar upon which the miracle occurred has always been kept in the Monastery at Floreffe.
St. Norbert was known for his devotion to the Eucharist, his frequent pronouncements on maintaining the utmost cleanliness about the altar and for combatting the Sacramentarian heresy. The Sacramentarians believed that consecrated Hosts held only metaphorical power and that they did not contain the Real Presence. St. Norbert was called to Antwerp to quell this heresy there. He succeeded. Afterwards, he was known afterward as the “Apostle of Antwerp” and the “Apostle of the Blessed Sacrament.”
