The following below from the current Code of Canon Law at the Vatican Library itself shows you exactly why ecumenical talks with the Roman Catholic Church are always futile; and it also again proves Martin Luther was absolutely right when he said:

The negotiation about doctrinal agreement displeases me altogether, for this is utterly impossible unless the pope has his papacy abolished. Therefore avoid and flee those who seek the middle of the road. Think of me after I am dead and such middle-of-the-road men arise, for nothing good will come of it. There can be no compromise (Online source, emphasis added).

Here, read it for yourself: 

Art. 1.

THE ROMAN PONTIFF

Can. 331 The bishop of the Roman Church, in whom continues the office given by the Lord uniquely to Peter, the first of the Apostles, and to be transmitted to his successors, is the head of the college of bishops, the Vicar of Christ, and the pastor of the universal Church on earth. By virtue of his office he possesses supreme, full, immediate, and universal ordinary power in the Church, which he is always able to exercise freely.

Can. 332 §1. The Roman Pontiff obtains full and supreme power in the Church by his acceptance of legitimate election together with episcopal consecration…

Can. 333 §1. By virtue of his office, the Roman Pontiff not only possesses power offer the universal Church but also obtains the primacy of ordinary power offer all particular churches and groups of them. Moreover, this primacy strengthens and protects the proper, ordinary, and immediate power which bishops possess in the particular churches entrusted to their care…

§3. No appeal or recourse is permitted against a sentence or decree of the Roman Pontiff. (Online source, emphasis mine)

And it matters not one whit what any individual Roman Catholics, theologian or not; or pretending Protestants, theologian or not; believe. The above is the official, allegedly infallible, and never-can-be-changed, position of the Roman Catholic Church herself. It’s way past time to wake up now…
