How can I come to the conviction and faith that the catholic church is the Only true church protected from teaching any Error if its Dogmas have developed from speculative positive theology out of a faith that is still to this day kept by the Orthodox churches??
First, IMHO you should not let the key assumption about SSC unexamined.
Then you could come to see that in any century dogmas have always conserved the same nature.
As for the faith of the 7 Councils, that has of course been conserved and defended by the CC .
As you know, and as it has been recently focused by Benedic XVI, the Church asks to consider her magisterial teaching in a hermeneutic of continuity. There is nothing she guards more than continuity in the teaching of the deposit of the faith.
You could theoretically “prove” that she was unable to fulfill this task of hers, but we have to allow her to require us to follow this hermeneutic of continuity in assessing that.
The very mission of the Apostolic Succession is delivering Sacred/Holy Tradition .
On top of that then, if anybody questions the faithfullness of the CC to Sacred/Holy Tradition, than the very raison d’etre of Apostolic Succession as a whole is gravely shaken.
In other words, if you come to think that the large majority of the present successors of the Apostles went seriously astray, we get just a few steps from the whole Protestant rejection of Apostolic Church, in its meaning that we share with Eastern and Oriental Orthodox brothers.
And the further question arises:
once the Solis Septem Conciliis tenet is questioned, by what objective principle ( therefore apart from my private judgment and inclinations ) can I today identify a given minority, or another one, of the successors of the Apostles, as the sole real bearers of Tradition ?
IMHO this way the “ tu quoque” argument of many Protestant brothers towards Apostolic Christianity, against our pointing to the divisions among their diverse folds ( ie that Apostolic Christianity is also a house inherently divided, and that the individual believer is therefore left there to his private judgment to settle which Communion preaches sound Tradition ) would be seriously vindicated . Wouldn’t it ?
I know the catholic church holds that the Christian theology evolves because not all truths Christ spoke could be understood until much later. But the way you can also see it is that when you start tanig these positive statements regarding dogmas and theology in general without complementing with the negative statements its sort of like a snowboard that keeps growing larger and larger. One Dogma leads to an inevitable consequence for aborter oart of faith and so on.
Wouldnt it be safe to say that negative statements of theology is superior converting anything not explicitly states by Christ? I have always been fascinated with Byzantine christianity but i always believed what I was told by catholics that the ONLY difference is that the now orthodox does bot accept the successor of Saint Peter as te rightful leader of christendom which I personally believe an think all early evidence points to. However, these are pretty major theological differences it at least seems like and considering the changes in catholicism and the doctrine of faith developing ine can understand why some orthodox can have a difficulty abandoning the Faith of their fathers and submit ti the authority of the Pope and the magisterium.
The point is: what was “explicitly stated by Christ” ? Was eg Trinitarian doctrine, as proclaimed in the Councils, explicitly stated by Him ?
If so, why all those dramatic disputations ? Why did it take centuries to get definitions on that ?
Even more relevant to our present dialogue : by whom and when was the end of the legitimate unfolding of the understanding of Revelation fixed ? Was this end in 787 ?
IMHO if any orthodox brothers teach that there should be no further Ecumenical Council after the Seven, because everything was already stated, are not keeping an ancient doctrine. On the contrary, they are teaching a novelty.
Indeed, consider that as late as the XV century there was not an a priori refusal to have a new Council.
The decisions of Ferrara-Florence Council were of course, a posteriori, ultimately rejected , after having been approved by almost all the Eastern representatives there, by the Eastern Churches,. But, mind you, they had not refused a priori the participation to a doctrinal Council, on the ground that anything explicitly taught by Scriptures and Tradition had already been settled since 787.
So, Solis Septem Conciliis is IMHO a novelty.
God bless you and thank you for your help!
