and the 1989 Profession of Faith vowing submission of the "mind and will to the authentic magisterium"

Catholics are indeed required to give a submission of mind and will to the authentic Magisterium.  You simply don't understand what the term means.

I'll let Msgr. Fenton explain what internal religious assent means:

This authority (of the papal encyclicals) is undoubtedly great. It is, in a sense, sovereign. It is the teaching of the supreme pastor and teacher of the Church. Hence the faithful have a strict obligation to receive this teaching with an infinite respect. A man must not be content simply not to contradict it openly and in a more or less scandalous fashion. An internal mental assent is demanded. It should be received as the teaching sovereignly authorized within the Church.

Ultimately, however, this assent is not the same as the one demanded in the formal act of faith. Strictly speaking, it is possible that this teaching (proposed in the encyclical letter) is subject to error. There are a thousand reasons to believe that it is not. It has probably never been (erroneous), and it is normally certain that it will never be. But, absolutely speaking, it could be, because God does not guarantee it as He guarantees the teaching formulated by way of definition’. 

Lercher teaches that the internal assent due to these pronouncements cannot be called certain according to the strictest philosophical meaning of the term. The assent given to such propositions is interpretative condicionatus, including the tacit condition that the teaching is accepted as true “unless the Church should at some time peremptorially define otherwise or unless the decision should be discovered to be erroneous.”

Catholics are indeed required to give a submission of mind and will to the authentic Magisterium.  You simply don't understand what the term means.

Ladislaus,
 
I have already discussed this issue with you before.  You know everything therefore you can learn nothing.  The last thread established that you really do not know what the Magisterium is.  You did not even know that it is part of the content of revelation and part of the act of revelation.

Not knowing what the Magisterium is, how could you possible arrive at the correct answer to the problem with the 1989 Profession of Faith with its requirement of unconditional submission of the mind and will to the authentic magisterium?  This question was discussed in detail and your objections never once produced any evidence beyond the authority of your own personal opinions.

The entire thread discusses this question that you just never grasped but it is important for anyone interested in defending the faith to understand.

I invite others to review the previous arguments exchanged and judge for themselves the merits of your claims.  I think they were worthless but that is for others to judge for themselves.
