That is the opposite of my interest here, which is to hear what others sincerely believe, without acrimony. Even those who believe things I strongly disagree with I want to hear spoken cleanly so that I can respond in kind, but argument, and not by emotion, by spiritual conviction and revelation, and not by intellect or pressure.
Yes, I think there is a linear curve indicating a move away from fundamental Christian beliefs from the time of the Reformation, both by Catholics and by Protestants. But neither am I sure that we can caricature either of these groups as necessarily following that curve?
Many can support Catholic resistance to Protestant arguments without doing anything more than protecting one's own sect. In other words, the argument may not involve truth at all, but only be a wish to protect the security of a particular organization.
Catholics today may hold to valid Christian dogma without being part of the dilution of doctrine carried on in Catholicism since the Reformation. At the same time, there are those whose resistance to Protestantism is more theological, with an interest in diluting truth. The same likely holds true for Protestants as well.
Yes, the Fundamentalists at the turn of last century wished to combat the trend towards Liberal Theology. And many since have seen the rise of the World Council of Churches as a step in the direction of accomodating aberrant Christian views, which is, after all, the essence of Religioius Liberalism.
As I said, the idea of "Faith Alone" is more complex than this simple statement. To one is meant that Christ alone is our Atonement. To another, Faith, properly, will include Works--not to self-atone, but rather, to obtain it from Christ as a gift. We must choose Christ above ourselves and repent of our own ways in order to respond in Faith to Christ's Word.
But for those who believe that Works and Rituals, like the Eucharist or belonging to the Catholic Church, are necessary for Salvation, we would offer "Faith Only" asw a remedy to this Socinian belief, or Pelagianism. It is either heresy or the approach of nominal Christianity to beliefs they cannot understand simply because they have not experienced it, or actually reject that experience.
Let me just say this about Armianism. I'm not Arminian--I'm much more on the side of Calvinism. But I'm also a believer in Free Will--much more so, perhaps, than either Luther or Calvin.
To explain this would require another thread, so I'll leave it at that. For now, I believe Christ alone is the virtue by which we are saved. But I believe God has endowed us in creation with His virtue to be able to respond to His Word. Thus, we can choose for Salvation without contradiction.
