Because Christianity was so diffuse, and also illegal and therefore kept underground, it
is hard to speak of a united “Christianity” in this period. A more accurate statement might be
that there were “Christianities,” that is, various forms of Christianity, with different takes on
the religion and its message. Gnostics, Montanists, Docetists, and others, debated about the
true nature of Christ, salvation, and the life of a Christian.
