Some proofs that the Latin Mass, in roughly its present form, is traceable to Pope St. Victor I (AD 189-199):
“Jerome calls Pope Victor the first Latin writer in the Church (Chronicon, ad an. Abr. 2209). Prior to him, Greek was the nearly universal language of theological discourse. Jerome mentions small theological treatises written by him in Latin. However, besides the letters touching the Easter controversy, none of Victor’s actual works is known. The question of whether he promoted the use of Latin in the Roman liturgy is an open one.
“It may have been during Victor's administration that the canon of scripture used at Rome, and which has been partially preserved in the Muratorian Fragment, was drawn up.”
