It's well known that Hellenistic culture did not cease after Roman domination of Greece, Asia Minor, Judaea, and adjacent regions. Many still spoke the common or Koine Greek (i.e. New Testament Greek). Educated ethnic Romans, even those before the principate such as Cicero, were fluent in Greek as well as their native Latin and freely mixed the two languages together in their letters. Well into the imperial period large numbers of immigrant Greek speakers lived in Rome and its environs. The Roman Empire was truly bilingual in a quite integrated manner.
WI the ethnic Romans (Carthaginians and Italians, for example) effectively destroyed Hellenistic culture and Koine Greek in the eastern provinces? What type of Latin would take the place of the common Greek? Would more Greek loanwords survive, given that these areas were previously populated with Greek speakers? In OTL, early Latin works of Christian scripture, apology, and commentary often contain many Greek loanwords.
