Appreciate the link. That was to a caucus thread, IIRC, so I will not comment on that thread. All of us would do well to NOT conflate the denominational institutions, being man made, with the True light of believers in the world but not of it.
I understand that as a Catholic you believe ONLY your institution is the True gospel carrier. It is useless to argue that point since there are other credible institutional orgs which would claim the same exclusivity. But as your link showed, it was the Spirit in the Apostles which brought forth the light unto men. We are tasked with continuing to allow THAT Spirit to shine forth in each believer, to the extent we yield to HIS Presence in us. The wick is not the light. The wax is not the light. The flame is the source of the light, the boundary where transition takes place.
The LIFE is in the blood of the creature. The blood is not the LIFE; the life is carried in the blood.
