Many Catholics hear about the virtues of the Blessed Virgin Mary, but few think about the fact that she is a public revelator: A prophetess who can bind in faith and morals.
Not only the Pope can bind in faith and morals, any prophet (and there are many in the Gospels). and Any public revelation (Pastor Aeternus. 4. 9) is binding on the Faithful (you must believe it in order to be in good standing).
Private Revelation is that given directly to a soul from God or an intermediary such as a divine agent (angel, saint) and is binding on the recipient. It is not binding on anyone else, and should not be denied (Acts 2:17).
These experiences are common and nothing to be worried about (Acts 2:17) since they have happened “throughout the Ages.” They are not necessarily indicative of Sainthood, but authentic revelations are an indicator. Proper Discernment is required.
Public Revelation is that given through a prophet(tess) or Apostle. It is binding on the Faithful to believe with a Divine and Catholic Faith. Everyone is bound to believe it, even non-Catholics who may not be culpable through ignorance and other factors.
The intent to bestow public revelation must be indicated to be binding. Fatima, Lourdes, La Sallete and other approved apparitions have no such indication from the Blessed Virgin. Not even an angel of God can change public revelation once dispensed.
New Public Revelation will be revealed when Christ returns, but no revelation (public or not) can change the Gospel.
This is a type of revelation that is “absolutely certain and infallible” (Council of Trent, Session 6, Canon 16). These are totally binding on the recipient. They admit no error and will never fail to be certain in the prophet (see above).
The Blessed Virgin suffered no effects of sin, such as pain in childbirth (Genesis 3:16):
So the Virgin became a mother with great mercies. And she labored and bore the Son, but without pain. ” (Odes of Solomon 19 [A.D. 80]).
Hence, again it is indicated that she had direct revelation. As Adam before the Fall, she suffered no ignorance, hence, as we see with Adam, had direct revelation.
