Traditional Breviary Martyrology and Holy Peter Mavimeno

In the traditional latin breviary there is a list of the martyrs we remember everyday.  Today one of the martyrs we remember is Holy Peter Mavimeno.  At Damascus in the year 743, he was ill and some muslims came to see him.  He told them some very unpopular traditional catholic truth. Look it up in the Latin breviary for today.  “Whoever does not embrace the Catholic Christian Religion will be damned, as your false prophet Mohammed is,” where upon the muslims killed him.
