These young men, who are trying to give their lives to God and His Church, have been nonetheless woefully misled (and dare we say, betrayed!) into accepting this terribly doubtful 'consecration' of Fr. Pfeiffer's. Only a precious few syncophants from OLMC will accept  these 'ordinations.' No other traditional group of priests or laity will accept them without a reordination by a valid bishop. 

Some will recall that 'Bishop' Neal Webster is of the highly controversial Thuc line.  Both his ordination and consecration are in doubt - see an excellent, well-researched breakdown of Webster's line here from The Recusant in Autumn 2020. 

Archbishop Lefebvre repeatedly condemned the Thuc line - see here - as did the old/traditional SSPX.

The sedevacantists condemn this particular so-called 'consecration' of Fr. Pfeiffer as invalid for all the bungling and mumbling that occurred in the recorded 'consecration' ceremony - and, again, Webster is himself a sedevacantist (and a Feeneyite).

And last but not least, the 'old' Fr. Pfeiffer himself spoke of the Thuc line as highly doubtful - see here.

Again, please keep these well-intentioned young men in your prayers and let us beg Our Lady that this 'ordination' does not take place, which will only generate more scandal and danger to souls! Think of all the potential invalid Baptisms, invalid Marriages, invalid Confessions, invalid Extreme Unctions, etc. that occur in such situations. 

Our Lady, Queen of the Clergy, pray for them!
