Speaking about apostate Roman Catholicism and the Evangelical and Catholics Together document a few years back on The John Ankerberg Show Dr. R.C. Spoul correctly points out the following:

The Roman Catholic Church condemns “sola fide! (L.)” Now if, please understand this, if “sola fide (L.)” is the gospel, then the Roman Catholic Church has condemned the gospel of Jesus Christ. Now, nobody who went to the Council of Trent, as a delegate, went there with the intention of condemning the gospel. The theologians of Rome really believed that they were defending the gospel and that the Protestants had in fact committed apostasy.

And I admire the Church, the Roman communion of the 16th century for at least understanding what apparently people don’t understand today, and that is what is at stake here. That they understood that somebody is under the anathema of God! And we can be as nice, and as pleasant, and as gentle, and as loving, and as charitable, and tolerant as we can possibly be, but it’s not going to change that folks. Somebody is preaching a different gospel!

And when Rome condemned the Protestant declaration of “Justification by faith alone” I believe, Rome, when placing the anathema on “sola fide (L.),” placed the anathema of God upon themselves. I agree with his [John MacArthur] assessment, that the institution [of the Roman Catholic Church] is apostate! (Online source)
