In the London Review of Books, reader Anthony Buckley (“God and Human Behaviour”, Letters, LRB, 30 June 2011) wonders what “would constitute evidence” for or against the statement that “religious people…are more likely to behave in virtuous ways than non-religious people“.
That is an interesting question. And it can be easily answered in Christianity. The Gospel of Luke (chapter 5, verses 30-32) says:
“But their scribes and Pharisees murmured against his disciples,saying, Why do ye eat and drink with publicans and sinners? And Jesus answering said unto them, They that are whole need not a physician; but they that are sick. I came not to call the righteous, but sinners to repentance.”
It seems logical to conclude that, according to the Messiah Himself, ”people who have [Christian] religious convictions” will be “on the whole morally worse than people who lack them“.
