Pope Francis wrote a letter to all Catholics, in which he vows no more sexual abuse cover-ups. Cool... So when pope does it, it’s called “a Letter to the People of God”? If I vowed not to cover for criminals, it would be called “basic human decency”.
The concept of sin is scary for believers, but for non-believers – it’s just foolish. Sinful is not the same as wrong, evil and immoral. Why not?
