Don't be so sure!

In a recent survey of religions of the Roman world, however, the authors opine that early Christian exhortations to religious exclusivity likely reflect many or even most Christians of the time taking a more relaxed attitude toward sacrifices to the pagan gods. Maybe. But, again, I find this sort of confident assertion puzzling. For I think that there is scant evidence for the assertion that the majority of Christians were quite so indifferent to the demands of their faith. Otherwise, how would we explain that it was the “orthodox” vision of Christian exclusivity that proved successful numerically against other version of Christianity that may have tolerated a less exclusive stance?— Destroyer of the gods: Early Christian Distinctiveness in the Roman World, page 57–58
