Now, I knew that "
Baruch" in Hebrew meant "Benedictus" (Latin) or "Euloges" (Greek).
Nonetheless, I am sceptic that Benedictus (or
Benedict, or the French
Benoit) have been used as vernacular forms for "
Baruch".
Anyway, it is possible that Eulogios, the bishop of Edessa (4th century), which is usually honored on
August 25th, spoke Aramaic and/or Hebrew and knew the meaning "
Baruch" of his name.
Benedictus has definitley been used as a vernacular form for "Eulogios".
