The masons are smart. They know about infallibility. They Holy Ghost cannot protect a false claimant from erring or from destroying the Church through reinvention.
But the Siri theory is not something I stand on as I prefer to trudge on the sure ground of sound doctrine and Divine Law.
It is quite easy to point out where the Church is not and who cannot possibly be the true Pope, this can be backed up by docuмented facts, Church teaching and Divine Law while with Siri we are piecing together what we think might have happened.
A big promoter of the theory proved to be consistently dishonest at times and I thus lost all interest in it. Another instance where someone's pet agenda trumps everything including truth that undermines that agenda.
We see this with Traditio. It has much truth but the main purpose seems to be to undermining the SSPX as much as possible and exaggerate the truth. That seems to be the goal more than just getting to the bottom or root cause of the great apostasy.
When one proves repeatedly to be an unreliable source in regards to intellectual honesty, even when they are repeatedly called on it, I cease looking to them. This is why I stay clear of the Remnant and Catholic Family News.
