Google "Catholicism and fundamentalism".
For example, t
he Catholics admit that they don't believe in the inerrancy and infallibility of the Bible, and that do so is "fundamentalist" in a derogatory sense according to Catholicism. The Catholics even criticize Evangelical Catholics:
"Fundamentalism is a relatively new brand of Protestantism started in America that has attracted a tremendous following, including many fallen away Catholics. How did this popular movement originate? The history of Fundamentalism may be viewed as having three main phases. The first lasted a generation, from the 1890s to the Scopes "Monkey Trial" of 1925. In this period, Fundamentalism emerged as a reaction to liberalizing trends in American Protestantism; it broke off, but never completely, from Evangelicalism, of which it may be considered one wing. In its second phase, it passed from public view, but never actually disappeared or even lost ground. Finally, Fundamentalism came to the nation’s attention again around 1970, and it has enjoyed considerable growth.
"What has been particularly surprising is that Catholics seem to constitute a disproportionate share of the new recruits. The Catholic Church in America includes about a quarter of the country’s inhabitants, so one might expect about a quarter of new Fundamentalists to have been Catholics at one time. But in many Fundamentalist congregations, anywhere from one-third to one-half of the members once belonged to the Catholic Church. This varies around the country, depending on how large the native Catholic population is."
Many of these Evangelical Catholics are Protestants who are Evangelical (Christian) and still Catholic at heart, just Evangelical Catholics and Protestants who would be still Catholic if the Catholic Church were Evangelical. Evangelical Catholics do not like the following criticized by the Catholic Church:
The fundamental doctrines identified in the series can be reduced to five: (I) the inspiration and what the writers call infallibility of Scripture, (2) the deity of Christ (including his virgin birth), (3) the substitutionary atonement of his death, (4) his literal resurrection from the dead, and (5) his literal return at the Second Coming.
Catholics particularly hate the following:
"Although the doctrine of the inspiration and inerrancy of the Bible is most commonly cited as the essential cornerstone of the Fundamentalist beliefs, the logically prior doctrine is the deity of Christ. For the Catholic, his deity is accepted either on the word of the authoritative and infallible Church or because a dispassionate examination of the Bible and early Christian history shows that he must have been just what he claimed to be—God.
"Most Catholics, as a practical matter, accept his divinity based upon the former method; many—the apologist Arnold Lunn is a good example—use the latter. In either case, there is a certain reasoning involved in the Catholic’s embrace of this teaching. For many Fundamentalists, the assurance of Christ’s divinity comes not through reason, or even through faith in the Catholic meaning of the word, but through an inner, personal experience."
In other words, Catholics have to lie about what Protestants and Evangelical Catholics believe. Protestants and Evangelical Catholics believe in grace through faith alone, and vice versa, based on what the Bible says. Protestants and Evangelical Catholics do not believe in a New Age "inner, personal experience". And the experience is not personal-- for "there are three that bear witness on earth: the Spirit, the water, and the blood; and these three agree as one."
There is nothing personal in salvation-- one must answer to and be saved by the Spirit. Salvation is not a choice, but an election and calling which all the members of Eloheinu Echad choose to confer on someone-- and thus the saved have no individual choice and are held accountable in regards to salvation:
14 What shall we say then? Is there unrighteousness with God? Certainly not! 15 For He says to Moses,“I will have mercy on whomever I will have mercy, and I will have compassion on whomever I will have compassion.” 16 So then it is not of him who wills, nor of him who runs, but of God who shows mercy. 17 For the Scripture says to the Pharaoh, “For this very purpose I have raised you up, that I may show My power in you, and that My name may be declared in all the earth.” 18 Therefore He has mercy on whom He wills, and whom He wills He hardens.
19 You will say to me then, “Why does He still find fault? For who has resisted His will?” 20 But indeed, O man, who are you to reply against God? Will the thing formed say to him who formed it, “Why have you made me like this?” 21 Does not the potter have power over the clay, from the same lump to make one vessel for honor and another for dishonor?
22 What if God, wanting to show His wrath and to make His power known, endured with much longsuffering the vessels of wrath prepared for destruction, 23 and that He might make known the riches of His glory on the vessels of mercy, which He had prepared beforehand for glory, 24 even us whom He called, not of the Jews only, but also of the Gentiles?
The blood, by the way, is the witness of and for particularly Jesus; and the water of baptism, and of particularly the Father and the Spirit-- maybe just particularly the Father, though (which is a long discussion).
