Well, I guess in this case ....you.
So how would you then describe the thousands of different non-Catholic denominations/ non-denominational, churches and sects throughout the globe if not "Protestant?"
Calling them Protestant is fine. What I am trying to point out is that there is no such thing as "Protestantism". There is no such thing as "The Protestant Church".
If I treated Catholicism and Eastern Orthodoxy as though they were the same thing, and then point out that disagreements between Catholics and Orthodox as evidence of the failures of both, every Catholic and Orthodox Christian here would be in their right to point out my error in doing this.
In the same way, treating every "Protestant" church as though it were part of some nebulous "Protestantism" and then pointing out "Ah! See, you all don't agree!" doesn't work.
If you want to understand Lutheranism, you have to understand Lutheranism, not talk about some nebulous "Protestantism"; as though Lutherans, Methodists, Baptists, et al were somehow all part of the same thing.
The term Protestant is helpful, historically and categorically, but it isn't how we live our lives. I don't live my life and faith as a "Protestant". But as a Catholic Christian in the Lutheran theological tradition.
Traced back, meaning five hundred years or less, correct? Also, by this statement, one might surmise what you are saying, is that "Protestantism" is non-existent in all of Eastern Europe and Asia.
To the first, it depends. I consider my Church to be the Holy Catholic Church which Jesus Christ founded. Dr. Luther isn't the founder of my Church, Jesus Christ is. Luther, like many others throughout the history of the Church, was just one theologian and reformer. My religion does not come from Luther, but from Christ and His Apostles. The holy fathers, creeds, and ancient councils are the fathers, creeds, and councils of the Church which I belong to.
As to the second question, not at all--there are plenty of Protestants in the East. The evangelical reform of the 16th century was largely centered in parts of the Holy Roman Empire and Scandinavia, but not exclusively of course; and likewise through missions the Gospel has been preached throughout the world by faithful preachers of the Gospel. Just the same as has happened in your tradition, such as the Jesuit, Dominican, and Franciscan missions to the Americas and in Asia. Through immigration and missions the religious topography of the planet has changed a lot in the last several centuries.
Oh, I do agree these churches have many different beliefs and practices. With that being said, would you agree this creates implications for doctrine and unity among these different non- Catholic churches and sects? this is why I asked the two questions at the end of my OP.
Of course it does. In the same way that the differences in beliefs and practices between your church and other churches creates implications for doctrine and unity.
I could not in good faith and conscience receive the Most Holy Eucharist in a Baptist church for example, they deny the true flesh and blood of Christ in His Supper. That is not a matter of ill will or hostility; but of confession, conviction, faith, and conscience.
"But for a Protestant, what is dogma? And how does it relate to the concept of Christian unity?"
Would the many different variants of Lutheran churches %100 agree with you?
The faith once and for all delivered is to be received and confessed. I have no idea if every Lutheran congregation and synod around the globe agrees with me that there is no official definitions for delineating the differences between doctrine and dogma. My understanding is that this kind of rigorous categorization is fairly unique to your tradition.
Meaning something other than Sacred Scripture or the bible alone..... Got it!
Have a Blessed Day!
Lutherans aren't "Bible alone". We adhere to Sola Scriptura, or more accurately Solum Verbum--Word Alone; but we have never taught or confessed that the Bible is the only authority in matters in doctrine and praxis, we have never denied the importance of the fathers, of the vital and essential importance of the Creeds. We have never denied the historic tradition of the Church as important and vital for the life of the Church.
What we have said is that the Scriptures alone are the Norma Normans (the Rule that Rules) of Christian teaching and practice, while the Creeds, the Confessions, these are the Norma Normata (the Rule that is Ruled).
Scripture takes precedence, it rules over the life of the Church, and no man is above it. Scripture therefore rules over our faith, guiding us, giving Christ to us for here in Scripture is Christ Himself.
As that most honored Doctor of the Church, St. Augustine himself has taught, there is but one Utterance in all of Scripture, and that Utterance is Jesus Christ Himself.
