Here is a start. It is at the very least evidence of an attempt to understand the mystery. To battle heresy.
A pastor once told me that whatever we say about God, He is more unlike that than He is like it. Our very best imaginable is infintesimal compared to God.
But we should try. And we can point towards the truth with our words, or we can point in the wrong direction.
I may not be able to explain the moon, but if I point to a streetlight instead of the moon, I am in error.
Well I think one stark fact has to be recognized in the middle of our controversies...
That BOTH the evangelical AND the Roman Catholic AND the Orthodox communions have Christ visibly working in them.
I think this ought to move us to humility on the way to trying to understand....
