From time to time, I see articles of this type posted by Catholics and I just have to shake my head. Do they think that Luther was our “pope” and we hold him to be infallible?

No, we don’t believe any of us are infallible. Luther was wrong on plenty of things, just like all of us are. So, we are not shamed when that is pointed out to us. Nor does it invalidate any of the things that he got right.

“but they seem to ignore the many beliefs Luther also publicly affirmed that the same faith communities vehemently reject. “

That comment points out simply the same facts that Luther realized later on in his life -- he opposed the newfangled ideas that came up with others who followed his lead -- he protested against a point and then others who followed rejected first the Real Presence in the Eucharist (which he and all subsequent Lutherans believe in) -- he was appalled by this, but then even more appalled by the third generation of reformers - the anabaptists etc. and the fourth -- the unitarians

He, Calvin and Zwingli were so appalled by people coming up with their own new half-interpretations (like the Unitarians rejection of the Trinity, or others Arianism) that they sought to have their own synod to encapsulate the faith as they believed it

But, back to the sentence, it does state a fact that many who celebrate Luther may not realize that he deeply, passionately believed in things that are inimical to them -- of course one does not include scholarly folks like you in this group.

If Protestantism of today is not Luther's Protestantism, it's probably also fair to say that the Protestantism of tomorrow will not be the Protestantism of today. Amongst those who think Luther erred in some regards, there will likely be a divergence of opinion in just which areas he erred and by how much, since as you say, "we don't believe any of us are infallible". This can be and is a progressive process which may be repeated over time leading to an ongoing evolution of thought and beliefs. History bears this out as we look around us at the present diversity of religious thought which considers itself Christian.

I guess what this means is that although today is celebrated as Reformation Day, it's Reformation Day every day somewhere, for somebody, as the underlying Protestant theology plays out through time and an individual, personal thesis is nailed to a church door somewhere.

Whether this is a suitable model for the propagation and safeguarding of revealed truth is a question which I'll let others decide.
