DEEDS: ERGA = works, lifestsyle
It seems right that the “doctrine” of the Nicolaitans was that it was all right to have one foot in both worlds and that one needn’t be so strict about separation from the world in order to be a Christian, This, in fact, was the “doctrine” of the Nicolaitans that Jesus “hated.”
Just as the men of Israel compromised themselves with the world and false religions, now the “doctrine” of the Nicolaitans was encouraging compromise. And compromise with the world always results in a weakened and powerless form of Christianity. But this thou hast, that thou hatest the deeds of the Nicolaitans, which I also hate. (Revelation 2:6)
