St Matthew (21 September)
Vidit ergo Jesus publicanum, et quia miserando atque eligendo vidit, ait illi 'Sequere me.'
Today's Latin text is a reading from S. Bede on S. Matthew (which inspired the current papal motto miserando atque eligendo):
Translation: Jesus then saw the publican and when he saw him, he chose him with compassion, saying "Follow me."
Bede, Homily 21 (CCL 122, 149-51)
