Not this crap gain. Yes, by all means, we'll take Stubborn's word for it instead, someone who can barely read English vs. not only Billot but all the theologians who taught the same thing. Cardinal Billot was highly respected by St. Pius X, to the point that he made him a Cardinal in 1911 even though he wasn't a bishop.
Yes, by all means accept the wrong opinion of the political activist Cardinal Billot as if it is dogma, but if you do and remain a trad, you are left without a rule of faith -or- embrace the NO and get your rule of faith back. So goes the sede mindset.
But all you readers should bow to Stubborn's wisdom instead, who dismisses this "error" with the waive of his hand, an error which somehow escaped the detection of the Vatican's entire Congregation of Faith.
The liberal idea of which +Billot opined, made it into the seminaries, catechisms and all the manifestations of the Church. Your rule of faith is one of those errors, an essential ingredient for the crisis btw. How else could these errors get into the books, seminaries and etc.? Answer that.
As +ABL said:
"After all of these liberal ideas have been infiltrated into the seminaries, the catechisms and all the manifestations of the church, I am now being asked to align myself with these liberal ideas. Because I have not aligned myself with these liberal ideas that would destroy the church, there are attempts to suppress my seminaries. And it is for this reason that I am asked to stop ordaining priests...."
