Anyway, Raoul, I don't remember exactly why I changed my avatar to a photo of Bp. Schuckardt. I used to have a stock image of St. Jude, which I changed to one of Bp. Cornelius Jansen after being accused of harboring Jansenist tendencies by one of this forum's more prolific members. Unfortunately, the gag fell flat because no one recognized Jansen. Then something someone said in another thread a few weeks later made me think of Schuckardt so I changed my avatar to an image of him, but that fell flat too because no one recognized him either. As time went by, I forgot the original reason I had put him on there but I left him anyway as he was the first "sedevacantist" and I was hoping someone would bring him up in one of our sedevacantist debates. That too didn't pan out, even after I explained in a thread who he was. In other words, nobody took the bait or even noticed him at all until you asked me about him last week.
About the man himself, I certainly don't know all the facts. He was quite controversial in his day, though. His followers have a website with some good info on it about customs, traditions, and liturgy of the pre-Vatican II days. I consult it every month as they post a prayer regimen for each month, as well as an explanation of the descriptions of Mary in the Litany of the Blessed Virgin Mary and some historical info on Saints, Holy Days, past Popes, etc. I don't know where his followers are now; they don't list any address or phone numbers on their website but they are still out there somewhere.
