Today is the optional memorial of St. Bruno. It is fitting, I think, that he be honored with an optional memorial, for his humility would prevent being desirous of being obligatorily honored by the universal Church. In fact, though his cult was approved by the Church in 1623, he was never canonized in the formal ceremonies common of the time. The Carthusian order wouldn't permit such pomp and ceremony to surround their humble founder.
Today would be a good day to watch Into Great Silence and drink some Chartreusse in his honor.
