Pope St. Damasus I (306-384)
As pope, Damasus opposed Arianism and other major heresies. At his suggestion, St. Jerome completed the Vulgate Bible. He successfully maintained the primacy of the Apostolic See, and welcomed the edict of Theodosius I, which made Catholism the religion of the Roman state. His interest in the martyrs led him to restore the catacombs.

Reflections from the Saints

He is the Illuminator; Truth, because He is from the Father; Life, because He is the creator; Bread because He is flesh.
– Pope St. Damasus I
