Misinformed and misunderstood

There is an argument made by Peter Kreeft and Mark Shea (among others) that says that for the most part Protestants are merely confused or ignorant of Catholic teaching rather than informed critics of it.  How else do you explain the glorious outworking of Catholic teaching in the lives of great Catholics, many of whom are recognized as such my both Protestants and Catholics?  All of the great Protestants (willingly or not) began their own half-broken branches of the Christian faith and continue to do so at present.  To claim as Ankerberg and Weldon do that each "genuine Christian church" has found general agreement in their common authority is a great insult and a grave testament to the validity of that authority.  How can agreement about ultimate truth cause and tolerate so much division?

 

In this regard, each Protestant division is not so far off course in claiming that they are the possessors of the purest truth.  With so much opposing teaching it is nearly incumbent upon each divided group to do so.  Add to that that such a claim is nearly irresistible to the searching conservative literalist and you have a firm foundation upon which to build a new congregation - and cause further division.  If scripture itself is the true authority by which each congregation or denomination forms its doctrine, then where they differ they must each claim to be right.  Would it not be of more benefit and a testament to unity for the leaders of each of these to come together and, bathed in prayer and guided by the Holy Spirit, come to a consensus about those things which are in dispute?
