Christians often accuse atheists for not having a definition of morality.
But it is interesting how the same Christians can decide that eating shellfish, wearing mixed fabrics is moral despite what Bible has to say on the matter. They pick & choose what to follow and what not to follow based on their own inbuilt sense of morality.
They can’t define the morality within them that helps them decide what to pick and choose, but neither can anyone.
I think, the very existence of countless flavours of Christianity is proof enough that they disagree on what to pick and choose. Some think picketing at military funerals or bashing gays is moral, whereas other think it is immoral. Some think properity gospel is moral other think it is immoral.
