I call him religious who understands the suffering of others.
As soon as we lose the moral basis, we cease to be religious. There is no such thing as religion overriding morality. Man, for instance, cannot be untruthful, cruel or incontinent and claim to have God on his side.
There is nothing that wastes the body like worry, and one who has any faith in God should be ashamed to worry about anything whatsoever.
