The Catholic Church has proclaimed five Dogmas about Virgin Mary, the mother of Jesus Christ:
1- Mary Mother of God, 431.
2- Mary always Virgin, before the birth of Jesus, during the birth, and after the birth of Jesus, 649.
3- Mary Immaculate: On December 8, 1854, Pope Pius IX issued the bull Ineffabilis Deus, which proclaimed the dogma of the Immaculate Conception of Mary, "preserved free from all guilt of original sin".
4- The Assumption of Mary, on November 1, 1950, when Pope Pius XII stated that Mary was "taken up body and soul into heaven," and "exalted as Queen of the Universe."
5- A fifth dogma is "Mother of the Church", proclaimed by Paul VI, Second Vatican Council, Nov. 21, 1964
6- Lately, the Pope is being urged to proclaim Mary with another three titles, with three dogmas:
- The Co-redeemer or Co-redemptrix,
- The Mediatrix, or Mediator of all graces,
- The Advocate for the people of God, Intercessor, Helper, Benefactress.
The Maternal Mediation of Mary is under its three essential aspects of Co-Redeemer ("the Mother Suffering"), Mediator("the Mother Nourishing"), and Advocate ("the Mother Interceding")... so, these three dogmas are interrelated and may be it is only one, because the roles of a mother, as heart of the family, are multiform but the truth of her motherhood is singular, only one!.
This last triple dogma would be the climax of the Age of Mary, and like all dogmas is right now highly debated within the Catholics, Protestants and Orthodox. In fact, the reason of any dogma proclaimed by the Church is to clarify and assert the truth on any important biblical issue when it is being debated with controversies among the faithful... this was the case of the declaration by the Church of the dogmas of the Trinity, the Divinity of Jesus, the Divinity of the Person of the Holy Spirit... all the dogmas declared were under high controversy at the time of their proclamation!.
Once the dogma is pronounced, all the doubts end, at least for the faithful of the Catholic Church.
THAT IS HERESY!
