Saint Concordius, Martyr of Spoleto was Christian saint and martyr of the 2nd century who began his life as a subdeacon in Rome imprisoned during the Christian persecutions of Marcus Aurelius and tried in Spoleto, Italy. Concordius was allowed his freedom if he would renounce his faith and worship a statue of the Roman god Jupiter. When Concordius refused, the judge had him beaten on a rack. After the torture, however, Concordius praised Jesus, after which he was thrown in jail. Two days later, he was offered a second chance and presented with a statue to worship. Concordius then spat on the idol and was promptly beheaded, c.175 AD. Concordius was canonized by religious officials at that time, and his feast day is commemorated by the Roman Catholic church on January 2 and by the Eastern Orthodox on June 4.
Saint Natalis was a Bishop of Milan from about 740. He governed in the strained period of Italian and Church history when the Lombards were being converted to the orthodox faith.
