Read the full account
The 1879 encyclical and subsequent Roman study-norms, as public Holy See acts, treated other Catholic schools as lesser. The dated lead instrument is Aeterni Patris. Curricular exclusion is a polarising governance of thought, not a thirteenth-century debate.
Context
Jesuit, Franciscan, and historical-critical Catholic work lost official oxygen. That is a documented reception cost.
Thomas Aquinas is not the sole author of every later object, law, or museum label that uses the name. Shared work with courts, excavators, printers, spouses, officials, and later states does not erase a documented role, and it does not make an ancient person the signer of a twentieth-century statute.

What the sources establish
Later competitions, monuments, translations, UNESCO listings, and museums are not converted into extra lifetime acts. That reading is an impact-path choice, not a property stored on the Fact itself. Confidence is stated on the impact path. A later English edition is not a recovered autograph. If a number is not in the two records named above, it is not supplied here.
