Saw Fr. “Bing” just the other night, on an EWTN program. But I haven’t heard anything about him developing the stigmata. His hands didn’t appear to be wrapped, or bandaged… and he seemed able to stand and walk. Maybe if you email EWTN, someone there might be able to update you.
An observation, though. I have heard of people “receiving” the stigmata. But have never heard of anyone “developing” the stigmata (slowly, over time?). So… this puzzles me, just a bit. Of course, all things are possible with God.
