The way doctrine is unfolded in the Catholic Church makes the date of something's being declared de fide subject to misinterpretation. In matters of Doctrine the Church has a function which is sometimes more judicial than executive.
The Assumption was believed by many for a long time, for centuries, and finally the Holy See responded with a declaration. So to look at the date of Munificentissimus Deus and conclude that the dogma is new is to make an, ahem, assumption.
Or the “immaculate conception’ of her who called the Son she was to bear her ‘savior’? Only sinners need a savior.
Really? May I take it then that you think guard rails, banisters, and things of that kind are useless? The person leaning on the railing around a balcony is not saved from falling because one can only be saved AFTER one falls? Last week an elderly lady was unsteady on her feet as she approached the Sacrament. I offered her my arm and we tottered up together and received together and I walked her back to her seat. She thanked me.
By your reasoning she had no cause to thank me since she had not fallen when I came up to save her from falling.

I hope I don't embarrass you by commenting that this story is very touching. You are a gentleman.
By who? Why so long to be an established belief which leads to a possible damnation exile from the Church? as well as, By what PRIMARY source was this “revelation” based on? (i,e First century sources please, which would have been all over the place like the Canons due to the miraculous event which would have furthered promoted Christ's Deity status during the 1st century)
Who is right, the ex cathedra of Munificentissimus Deus which states you are in spiritual exile/”dead” if you even question the Pope's “superpower” of declaring dogma without a primary source/tradition from various Councils/Synods that were ESTABLISHED in order to reach consensus, the Dormition of the Theotokos, which does not kick you out of the Eastern Orthodox Church if you question events that lack a primary source (Well understood, due to the early Church Fathers’ stance), or not caring about Mary's death/assuming being assumed by Christ, because it is perceived as personnel, an attempt to argue from silence, as well as provides not one single ounce of meaning towards the salvation of the (Soul) individual (Unless you believe Pope Pius XII’s “superpower” which another mother Church, the “Orthodoxes” say, where did that power come from?) .
