Andrea Grillo is such a detestable character. But, unfortunately, we are forced to return often to covering him because of the outsized influence he was given by the late Francis. As Rorate mentioned in the earlier words about this matter,
The detestable Italian professor was introduced by some malevolent Vatican spirit to Francis and created the document that would later be signed by the late pope as "Traditionis custodes", whose aim is explicitly to destroy the Traditional Latin Mass in the long term.
Last month, we covered the first consequences of his tirades against the (now newly canonized) Carlo Acutis, when his own university disowned him.
There are criticisms to be made of the Acutis canonization, but mostly regarding (as often in recent decades) an accelerated procedure, not the person himself. By all accounts, Acutis was really a fine boy who, despite growing up in a secularized, barely nominally Catholic, family, was saved by a supernatural love for the Blessed Sacrament.
