How could the Christian Church, apparently quite willingly, accommodate this weird megalomaniac [Constantine] in it's theocratic system? Was there a conscious bargain? Which side benefited most form this unseemly marriage between church and state? Or, to put it another way, did the empire surrender to Christianity, or did Christianity prostitute itself to the empire? It is characteristic of the complexities of early Christian history that we cannot give a definite answer to this question.
