St. Erhard, Abbot and Confessor, Native of Scotland
[Called by Mersæus and other Germans, Eberhardus.] HE was a Scotchman by birth, and being well instructed in the scriptures, went into Germany to preach the gospel, with two brothers. He taught the sacred sciences at Triers, when St. Hydulphus was bishop of that city, whom Welser and some other take for a Scot, and one of our saints brothers. When St. Hydulphus resigned his bishopric to end his days in retirement in 753, St. Erhard withdrew to Ratisbon, where he founded a small monastery, and is said to have been honoured with miracles, both living and after his death, which happened in that city. He was commemorated on this day in Scotland, but in Germany, on the 8th of January. See Peter Merssæus, Catal. Archiep. Trevirens. M. Welserus, l. 5. Rerum Boiocar. ad an. 753.
