One of the Catholic Church’s most authoritative associations of Mariologists has published a detailed and sharply worded response to Mater Populi Fidelis.

The International Marian Association Theological Commission released its 23 page critique on the Feast of the Immaculate Conception, describing elements of the document as erroneous, “unfortunate”, and in need of “substantial clarification and modification”. While recognising the note as part of the ordinary Magisterium, the commission stressed that it stands on a “lower level” than direct papal teaching and is therefore open to respectful theological correction.
