From National Catholic Register:
One of the Catholic Church’s foremost associations of Mariologists has issued a strongly critical response to Mater Populi Fidelis, a recently published Vatican doctrinal note that has been criticized for its diminution of some long-established devotional Marian titles.
In a 23-page document published Dec. 8, the Feast of the Immaculate Conception, the International Marian Association Theological Commission (IMATC) points to various elements of Mater Populi Fidelis (The Mother Of the Faithful People of God) which it calls erroneous, “unfortunate,” and says are in need of “substantial clarification and modification.” They describe a significant element of the document as resembling Protestant rather than Catholic theology and urge, “in a spirit of true synodal dialogue,” for Mater Populi Fidelis to be re-evaluated.
