”If Christians want us to back off, then they need to admit that we can be good without a god…”
Allow for me to say, the sort of *good* that exists for this person apart from any belief in God is the sort of goodness by which I loudly proclaim you can be *good* with.
Anyone attempting to answer the question, “what does it mean to be human?” Necessarily, steps beyond the bounds of empirical/scientific inquiry. This is not to say the natural sciences do not play a part in their response, it is to say the part it plays is not because anything empirical told them so.
"If salvation is not a real participation in the resurrected life, the glorified and grace-filled Humanity of Christ, then we are left with a man-made religion of “ideas” and concepts, an imaginary “relationship” with God that cannot truly transform and save us."
— Father Michael Shanbour
