That statement is simply not true.
Here are the statements of faith for several denominations or independent churches for anyone to peruse for themselves to see what kind of "divisions" there are within "Protestantism" (as the term is used by Catholics to describe anyone not Catholic).

>>That statement is simply not true.
As I said in my post: “Even if Protestants disagree, we all look to Jesus as the answer. If I am Calvinist and my friend is Arminian and we have significant differences on many theological issues, the article overlooks the fact that we both look to Christ and hear the counsel of the Holy Spirit. I do not think that Calvin saves me or condemns my friend. He does not think that Arminius or Wesley saves him or condemns me. So, our differences do not matter.”
What are you trying to show in that lasting of statements of faith? Are you saying that they do agree in the important things or that they disagree?
