It’s a concept that is often misunderstood, as on this thread. I can see the God in people who are not believers. When they take joy in giving to others, when they make peace between people instinctively, when they see the futility of earthly desires.
I know the difference between having Christ and not having Him. I believe Francis is talking of how to convert the world. You do it by seeing the beauty in others, not by seeing the lack of Christ. Only God can really convert people of course.
I am no longer a Catholic, by the way. I have great hopes for Francis. He is a bit unsophisticated (pace Catholics on this thread), but that can be a positive thing, sort of like the tea party. They are political amateurs but their heart is so incontrovertibly in the right place.
A friend of mine thinks Francis is Peter the Roman. Why? Because of alpha and omega, the first and the last.
I don't see God in everyone because not everyone has God in them.
What I see is people who are made in the image of God, for fellowship with God, who are slaves to sin and the enemy, and are in need of reconciliation with God through redemption through Christ.
