I'm not sure we can fully comprehend how radical an idea that was.

So, the difference between early Christianity and the larger religious environment went beyond simply preferring one particular deity among the others, and beyond an exclusivist worship practice. There were also different notions about what the term “god” (Greek: theos) meant, or at least for Christians there was a distinction between “gods” and the one God (ho theos = literally, “the god”). The early Christian notion posited one utterly transcendent deity who could not be compared with the many traditional gods at all and could not even be comprehended fully, so great was this God. And yet, and with equal emphasis, Christians maintained that this one deity, not some subordinate being, was the sole creator of all things and also sought to relate to the world and humanity in redemptive love, such that even the humblest of individuals could be recipients of this love and could be adopted into a filial relationship with this God.— Destroyer of the gods: Early Christian Distinctiveness in the Roman World, pages 65–66
