Saint Angelus (Italian: Sant'Angelo; 1185 – 5 May 1220) was a Catholic convert from Judaism and a professed priest of the Carmelites.
He and his twin brother were converted to the faith once their mother did so while both became ordained priests and Carmelite friars.
But unlike his brother he retreated into the desert to a hermitage after his ordination.
But he emerged once he was instructed to go to the Italian mainland to evangelize as well as to meet with Pope Honorius III to have him approve a new rule for the Carmelites.He was slain whilst preaching and was believed a saint after his death.
The Carmelites venerated him as such until Pope Pius II beatified the slain priest during his pontificate circa 1459.
