Perhaps we are just talking passed one another here.
My question was about proclaiming new dogmas, not about the received Faith.
"Unfortunately, I cannot see any reason given for the expression of new dogmas."
For instance, it is certifiably not a dogma now, everyone seems to agree on this point… so why make a dogma we have never had before?
I missed your comment when you posted it, but I will reply now.
Are you familiar with the various grades of statements made by the Catholic Church? Only some are formally dogmas that must be belived as part of the faith, and others are less certain, but may be believed. When there is a teaching that threatens the faith, then the Church may declare a dogma to defend the faith. Many teachings that are traditional are not declared as dogma. Common to the Eastern Orthodox and Roman Catholic, the first seven ecumenical councils contain many dogmas. Based upon the history of the ecumenical councils, one can understand that it took time to declare the mysteries. The Catholic Church summarized the dogmatic and non-dogmatic faith at the Vatican II in Lumen Gentium.
From the Eastern Church, Mary is the mediatrix for our salvation because He suffered the Passion of the Cross in the flesh that He assumed from her as expressed in the Tone 3 Resurrectional Theotokion.
Tone 3 Resurrectional Dismissal Theotokion
We praise you as the mediatrix of our salvation,
Virgin Theotokos.
For your Son, our God, Who took flesh from you,
accepted the Passion on the Cross,//
delivering us from corruption as the Lover of Man.
And we also have this from the Divine Liturgy of Saint John Chrysotsom:
“Through the prayers of the Theotokos, save us who sing to You, Alleluia.”
From Vespers:
“Christ our God, the existing one, is blessed always now and ever and unto the ages of ages.”
“Most Holy Theotokos save us.”
“More honorable than the Cherubim…”
“Glory to you, O Christ, our God and our hope….”
In the Catholic, Lumen Gentium VIII, item 62 is stated:
Therefore the Blessed Virgin is invoked by the Church under the titles of Advocate, Auxiliatrix, Adjutrix, and Mediatrix.(16*) This, however, is to be so understood that it neither takes away from nor adds anything to the dignity and efficaciousness of Christ the one Mediator.(17*)
