What would you remove from Christianity if you could?
Envy? Chastity? Gluttony? Gossip?
Lewis had this to say.
Reminded me of that quote about hell being locked on the outside.
There is no doctrine which I would more willingly remove from Christianity than this, if it lay in my power. But it has the full support of Scripture and, specially, of Our Lord’s own words; it has always been held by Christendom; and it has the support of reason. If a game is played, it must be possible to lose it. If the happiness of a creature lies in self-surrender, no one can make that surrender but himself (though many can help him to make it) and he may refuse. I would pay any price to be able to say truthfully ‘All will be saved.’ But my reason retorts ‘Without their will, or with it?’ If I say ‘Without their will’ I at once perceive a contradiction; how can the supreme voluntary act of self-surrender be involuntary? If I say ‘With their will,’ my reason replies ‘How if they will not give in?’
