Satan, the Devil, and the Talking Snake Evolved into One Person!

Satan just isn’t what he used to be! The devil (diabolos in Greek) wasn’t always what he is today. At one point, the devil and Satan were two different persons. Moreover, that talking snake of Genesis was still another person. But by the time we reach the New Testament, all these three other-than-human persons had become one and the road was set for a Christian take on the Evil One.
Strange, huh? Not really. Theology develops.
