SSPX of the Strict Observance

On September 21, 2012, the announcement came forth like the trumpet of the Apocalypse: a new Society of St. Pius X of the Strict Observance was founded on August 10, 2012, by the Vienna (Virginia) Declaration. The founding members are five leading priests of the SSPX. 25 more SSPX “resistance priests” have been identified so far and are expected to form the core of the SSPX-SO.
Described in the words of the Declaration as a “united core of priests faithful to the position always maintained by Archbishop Lefebvre,” Frs. Joseph Pfeiffer, Ronald Ringrose, Richard Voigt, David Hewko, and Francois Chazal, coming from various areas around the world, signed the founding documents. Joining the priests in the SSPX-Strict Observance are a number of SSPX religious and laity, to name just a few: Mother Ann-Marie Simoulin, Dom Thomas Aquinas (Benedictines of Brazil), and Dr. David White, who has previously given classes at the SSPX seminary in Winona, Minnesota.
The five founding fathers have elected Fr. Joseph Pfeiffer as their leader for a term of two years (compared to Fellay’s dictatorial 24 years). The fathers have refused to give up the name “Society of St. Pius X” because “we did not change the message; the official line of the [Neo-]SSPX has changed.” Although the founding fathers note that Fellay has not yet signed any “sellout deal” with Newrome, they publicly “withdraw the exercise of obedience to him for motives of Faith until this crisis is over,” in order for the priests to maintain obedience to God in their sworn Anti-Modernist Oath. Ironically, this was the same Anti-Modernist Oath to God that Fellay himself swore when he entered Major Orders with Archbishop Lefebvre.

This doesn't surprise me. Along with praying for the SSPX to fully, we must pray for this splinter as well....but why SSPX-SO?

I think SSPX continuing sounds better.
