Paul rejected the true faith? Who knew?
Ephesians 2:1-10 2 And you were dead in the trespasses and sins 2 in which you once walked, following the course of this world, following the prince of the power of the air, the spirit that is now at work in the sons of disobedience— 3 among whom we all once lived in the passions of our flesh, carrying out the desires of the body and the mind, and were by nature children of wrath, like the rest of mankind.4 But God, being rich in mercy, because of the great love with which he loved us, 5 even when we were dead in our trespasses, made us alive together with Christ— by grace you have been saved— 6 and raised us up with him and seated us with him in the heavenly places in Christ Jesus, 7 so that in the coming ages he might show the immeasurable riches of his grace in kindness toward us in Christ Jesus.
8 For by grace you have been saved through faith. And this is not your own doing; it is the gift of God, 9 not a result of works, so that no one may boast. 10 For we are his workmanship, created in Christ Jesus for good works, which God prepared beforehand, that we should walk in them.
Actually, the “heresy” or oft-repeated canard among RCs is that sola fide equates to a faith that is alone, when it distinctly does not.. Rather it means that while faith and works go together like light and heat, it is precisely faith that appropriates justification, as seen in Acts 10 and allowed in the Roman Catholic doctrine of baptism of desire, but by not by a kind of faith that would remain alone. See REFORMATION FAITH + WORKS.
And in reality, what Roman Catholicism fosters is the very thing that her apologist accuse sola fide of promoting, that of “easy believism,” as due to Rome's promoting of herself and her powers and merits, Catholics trust that she can get the most nominal of Catholics into glory (eventually, though Ratzinger speculates that purgatory may involve "existential" rather than "temporal" duration; something one experiences, but experiences in a moment), and whom she treats as members in life and in death (but when they converted to become conservative evangelicals is the greatest concern shown).
Also, as Jamieson, Fausset and Brown provide,
that they may — The Greek includes also the idea, They are blessed, in that they SHALL rest from their toils (so the Greek). and — So B and Andreas read. But A, C, Vulgate, and Syriac read “for.”
They rest from their toils because their time for toil is past; they enter on the blessed rest because of their faith evinced by their works which, therefore, “follow WITH (so the Greek) them.” Their works are specified because respect is had to the coming judgment, wherein every man shall be “judged according to his works.” His works do not go before the believer, nor even go by his side, but follow him at the same time that they go with him as a proof that he is Christ’s.
And Henry,
Blessed are the dead that die in the Lord from henceforth, etc. Here observe, (1.) The description of those that are and shall be blessed - such as die in the Lord, either die in the cause of Christ, or rather die in a state of vital union with Christ, such as are found in Christ when death comes. (2.) The demonstration of this blessedness: They rest from their labours, and their works do follow them. [1.] They are blessed in their rest; they rest from all sin, temptation, sorrow, and persecution. There the wicked cease from troubling, there the weary are at rest. [2.] They are blessed in their recompence: Their works follow them; they do not go before them as their title, or price of purchase, but follow them as their evidence of having lived and died in the Lord; and the memory of them will be pleasant, and the reward glorious, far above the merit of all their services and sufferings.
Rather than Rv. 14:13 contradicting sola fide, it supports it (but not purgatory), as it is not any kind of faith that saves, but one that effects works. And as faith is known by what it effects, so believers are judged by God to be believers on account of their works as and rewarded accordingly as "worthy." (Mt. 25:23,33-40; Rv. 3:4) But evidence to the contrary of the straw men of this fringe Catholic is either ignored or blithely dismissed (and who also resorts making things personal in order to do so). And thus he is.
