In the Roman Canon, after St. Alexander, we find St. Marcellinus and St. Peter.
St. Marcellinus was a Priest of, and St. Peter was an Exorcist, of the Roman Church. Of course, this St. Peter is not the same person as the Apostle named earlier in the Roman Canon.
St. Peter, while in prison, had delivered the daughter of the jailer, Artemius, from an evil spirit, whereupon the whole family of Artemius was converted and baptized by the Priest Marcellinus. Thereupon Sts. Peter and Marcellinus were led outside of the city for execution, as far as the so-called Black Forest, where they themselves with joy cleared the place in the thickets, and then bowed their head under the sword. On account of their martyrdom the place was afterwards called the White Forest. In the ninth century, their bodies were brought to Seligenstadt by Eginhard, the private secretary of King Charlemagne, where they repose in a magnificent silver shrine. Their feast is kept on June 2.
St. Marcellinus and St. Peter, pray for us!
For the Greater Glory of God,
