Unfortunately I get the impression that many "christian" republicans take the bible not as a guide on whom to love (fairly certain that Jesus guy said "everyone,") but on whom they think it tells them they should hate.
Jesus' whole shtick about helping the poor and sick selflessly, no matter the cost to oneself, and the directive to eschew wealth in favor of doing good to as many people as possible? More of a recommendation, really.
That one passage from the old testament about gays being icky? CHISEL. IT. IN. STONE.
