And that’s the “Catholic Problem” when Catholics speak about Protestants and their belief.
There are soooooooo many Protestant Churches, they have their creeds and catechisms and their “founders” (although they of course haven’t founded anything new!). But the important point is: They are all part of the One Church founded by Christ at Pentecost and have the same core beliefs. And that’s what Publisher wanted to say some posts above mine!!
If we talk about Baptists, as we do in this thread here, - please forget the other Protestant Churches.
We are talking about Baptists then! Not about SDA, nor Lutherans, nor Presbyterians,nor Anglicans nor any other Protestant Church and most importantly not about “the Protestants”.
And Baptists even have more in common than the Baptists and Lutherans, let’s say.
The only real difference is the stress (as also already Publisher has pointed out above.)
Baptists believe in sola fide, sola gratia and sola scriptura. They believe in giving one’s life to Jesus and the Credo Baptism.
And don’t tell me the various Baptist groups you so often mention don’t! They do. For sure.
If I know emmigrated to the US and would join a Baptist Church there, the core believes would be exactely the same than in the Baptist Church I am visiting right now here in Austria.
I think what most Catholics forget to consider is that since Zwingli and Calvin the “Low Evangelical Churches” (To use an Anglican term here!

and meaning Reformed and Presbyterian Churches as well as “born again Churches”; without SDA in this case.) are completely independent!
They have their believes in creeds and catechisms, but there is no “leadership” like among JWs, LDS, SDA and the Catholic Church. - The Anglican Church is similar, although they have dioceses and not single parishes. Some goes for the Orthodox Churches - (A Patriarch is a bishop, right? And not “a pope”?).
To Thomas 31: No wonder that you got to now so many different believe-systems if you church-hop in the “Protestant Jungle”.

- What you apparently did.
