I've asked you several sincere questions to which you've yet to answer. Let's just try one.
Do you support the proposed fifth marian dogma?
A simple yes or no.
<
> It is now time for the church, at the summit of this Marian era, to proclaim and define the fifth and final Marian doctrine, that is, Mary's universal mediation as Coredemptrix, Mediatrix of all grace, and advocate for the people of God. http://www.ewtn.com/library/MARY/MEDIATRI.HTM
I did answer that before. AFAIK, the dogma in question (in my experience, Catholic dogmas are not numbered) is part of the Ordinary Magisterium of the Church. Therefore, it is true.
I have no opinion on whether it should be solemnly defined.
Why do you care?
