A fundamental characteristic of liberalism is inconsistency.
The SSPX leadership openly condemned, humiliated, and punished Bp.Richard Williamson for publicly questioning the "official" 6 Million Gas Chamber Jєωιѕн narrative which has never been proven, but which has been given a sort of de facto dogmatic status in the Judaizing Conciliar Church. (That leadership is still waiting for the good bishop to retract his "historical heresy," which His Lordship to his credit has not done.)
Today, the SSPX leadership is not only giving Fr. Paul Robinson carte blanche to promote Big Bang, it is even instrumental in helping him do it despite the fact that Big Bang has never been proven and in fact stands in direct contradiction to the Apostolic Tradition, Scriptures and the teachings of the Church. (Three Popes -- Paul V, Urban VIII and Alexander VII -- have officially declared that heliocentrism is opposed to Sacred Scripture.) Perhaps needless to say BB is the status quo cosmological narrative of the Conciliar Church and seemingly almost all atheistic and agnostic scientists.
Truth be known, BB was invented by Hubble and the Jesuit Fr. Lemaitre (he dismissed the details of Genesis 1 as story-filler) to do an end run around the mounting evidence that the Earth was at the center of the universe.
