Actually, in the Greek, anti can mean instead of as well as against. John spoke of many anti-Christ’s, just as Jesus spoke of many false Christ’s. The references are parallel. Romney doesn’t have to be THE antichrist to be AN antichrist, and considering how completely Mormonism swallows up and displaces the simplicity of the Gospel, I do not find it a stretch to see Romney in that role.
Yes as in anti-Christianity...
and as a temple worthy member of the Mormon religion, bishop and high priest Romney is indeed that...
