Partly -- remember that Christianity spread in non-Roman parts as well: into Ethiopia, into Persia, Central Asia, Mongolia and China (the Assyrian Church), into India (the Syro-Malabar, Syro-Malankar Church) and into ARabia and Germania (Arian heresy)

But yes, the Roman Empire did help with the spread of Christianity -- one could argue that was God's will -- that The City was put on earth for that purpose..
