The "Father Williamson" fiasco seems to be connected to the (at least at one time) practice of the SSPV conditionally confirming anyone that received Confirmation from Bp. Williamson, because Bp. Williamson was supposedly ordained to the priesthood with one hand.
However, that still doesn't make a lot of sense, because Fr. Jenkins should then refer to Bp. Williamson as just "Mr. Williamson", if he believes the one handed ordination to be invalid.
Ultimately, this goes to Fr. Jenkin's rejection of "The Thucs" and his refusal to called Bps. Dolan and Sanborn bishops... and is now bleeding over into how he refers to Bp Williamson.
Fr. Jenkins really needs to give this up. It is tiring, petty, and childish.
