While it’s certainly true we Lutherans have been rather wayward over the last 500 years, and I will say that only a few of our churches could rightly be called ‘catholic’.
But, It’s here where I get to poke our Catholic friends and remind them of their novel dogma that have been promulgated over the last few years. That if the Catholic church were to also remain unchanged, our ecumenical dialog would be much more fruitful. I daresay the Orthodox probably also object to the new Catholic dogma as well.
Sorry you have been misinformed. The Popes nor the Communion of bishops ever changed a Church dogma nor invented any new ones. Infallibility has always protected Peter from doing so even at the cost of many Popes martyrdom for the Catholic faith. Yes it’s true our first Pope Peter walked on water with Jesus, but that is not the dogma of infallibility that those who have falsely object to Jesus infallible teaching to be with Peter until the end. But that is a defined doctrine from which all doctrines have been infallibly declared by the Popes and the Bishops in communion from Church Councils.
Those Orthodox church’s who refused to attend or were prevented from attending these councils by their Emperors, have objected from schism and afar. Many have returned to full communion, once the ecumenical efforts were put forth.
Which confirms and defines the Church’s definition of Ecumenism that produces fruit in fullest sense.
We cannot have an ecumenical dialogue in the official capacity until Lutherans Learn their roots of Catholicism as believed since the apostles themselves.
Applying your new man made doctrines of Sola fide, sola scriptura to the 2000 year old Catholic apostolic Traditions and defined doctrines, will never reach ecumenical dialogue between our communions.
There are no new doctrines in Catholicism, but defined, clarified apostolic teachings that fend off heretics, heresies that have attacked them.
That is why Jesus gave Peter singularly the keys of binding and loosing on earth, not only to protect Jesus flock from error, but to fend off false shepherds (man made teachings) and wolves (false prophets). Infallibility is guarantee from heaven that the gates of hell will never prevail against Jesus Church His Mystical body.
And before you reach for help from an Orthodox position, learn first that every apostolic see including any Orthodox Church have fallen in and out of some form of heresy. Except Peter and his apostolic successors in the Popes. The popes alone could never have done this alone without Infallibility before it was ever needed to be defined or clarified in order to prevent the infection of heresies such as mans false idea of freedom in Protestantism, communism and the list goes on. Infallibility has always been in the Church and Jesus has never left her orphaned
If we can have an ecumenical dialogue. You would allow the freedom of defined Catholic doctrines to be shared with you , without you contesting them with your new found freedoms in the sola theology invented by men. These will never accept the apostolic doctrines because your man made theologies are subject to change, that is why you cannot accept Jesus giving the keys to Peter with the commission to feed and tend Jesus flock, not Peter’s flock.
Every time you force your changeable theological position to any of the defined unchangeable Catholic doctrine (no matter in what age it was defined not invented), the dialogue is never ecumenical.
Your Lutheran commentaries is a dialogue of a faith that reveals some similarities, that has the content to reach an ecumenical dialogue with Catholicism.
So Long as Lutheranism holds to its Concords and doctrine definitions, as a whole the Lutheran position will always find a reason to protest an Apostolic teaching or Catholic doctrine, due in part from the Lutherans freedom of men.
Whereby the Catholic Church does not have the freedom of men to Change a divine infallible revelation or teaching in the Church. Catholicism is never a democracy of men to decide on faith and morals. Catholicism is under a Monarchy our King Jesus in heaven with His vicar Peter, He commissioned on earth.
Lutheranism refuses the authority of Jesus Vicar (Peter) on faith and morals. Lutheranism holds to it’s own authority that can change, it was not divinely instituted by Jesus Christ. The only divine office Jesus consecrated to himself was the office of Peter (Pope) and the apostles (Bishops).
