Good point Yjin, thanks.  I should have been more clear. When we "find God" through our religious faith, - the "Good" we rely on is what that religion tells/teaches us. Often this involves rejecting what another religious denominations or faith systems holds. We also "find God" through reflection on what it means to be human, what we Christians conceive as  "the image and likeness of God" in us, in creation. It is my opinion that this route which leads to the "common good", through reflection and reason, can also lead to God. But on the way, it instructs us on what we all hold in common.  At least, that is how I see it. That is what I was trying to clarify when I wrote: "This is more of a human issue before (on the way, by reason before faith) it is a faith one."
