Bringing forth good fruit is essential to Salvation as Christ Himself stated it in spite of Protestantism teaching that Christ was wrong and any requirement to bring forth good fruit is "works salvation" And just what convenience store do you get your definition of Protestantism and what it teaches in this regard? Since RCs infer we follow Luther in all he says, let us hear him and others (in context, unlike frequent RC quotes):
In his Introduction to Romans, Luther stated that saving faith is,
a living, creative, active and powerful thing, this faith. Faith cannot help doing good works constantly. It doesn’t stop to ask if good works ought to be done, but before anyone asks, it already has done them and continues to do them without ceasing. Anyone who does not do good works in this manner is an unbeliever...Thus, it is just as impossible to separate faith and works as it is to separate heat and light from fire! [http://www.iclnet.org/pub/resources/text/wittenberg/luther/luther-faith.txt]
This is what I have often said, if faith be true, it will break forth and bear fruit. If the tree is green and good, it will not cease to blossom forth in leaves and fruit. It does this by nature. I need not first command it and say: Look here, tree, bear apples. For if the tree is there and is good, the fruit will follow unbidden. If faith is present works must follow.” [Sermons of Martin Luther 2.2:340-341]
“We must therefore most certainly maintain that where there is no faith there also can be no good works; and conversely, that there is no faith where there are no good works. Therefore faith and good works should be so closely joined together that the essence of the entire Christian life consists in both.” [Martin Luther, as cited by Paul Althaus, The Theology of Martin Luther [Philadelphia: Fortress Press, 1963], 246, footnote 99]
All believers are like poor Lazarus; and every believer is a true Lazarus, for he is of the same faith, mind and will, as Lazarus. And whoever will not be a Lazarus, will surely have his portion with the rich glutton in the flames of hell. For we all must like Lazarus trust in God, surrender ourselves to him to work in us according to his own good pleasure, and be ready to serve all men. And although we all do not suffer from such sores and poverty, yet the same mind and will must be in us, that were in Lazarus, cheerfully to bear such things, wherever God wills it.” [Sermons of Martin Luther 2.2:25]
“This is why St. Luke and St. James have so much to say about works, so that one says: Yes, I will now believe, and then he goes and fabricates for himself a fictitious delusion, which hovers only on the lips as the foam on the water. No, no; faith is a living and an essential thing, which makes a new creature of man, changes his spirit and wholly and completely converts him. It goes to the foundation and there accomplishes a renewal of the entire man; so, if I have previously seen a sinner, I now see in his changed conduct, manner and life, that he believes. So high and great a thing is faith.”[Sermons of Martin Luther 2.2:341]
“For it is impossible for him who believes in Christ, as a just Savior, not to love and to do good. If, however, he does not do good nor love, it is sure that faith is not present. Therefore man knows by the fruits what kind of a tree it is, and it is proved by love and deed whether Christ is in him and he believes in Christ. As St. Peter says in 2 Pet. 1, 10: "Wherefore, brethren, give the more diligence to make your calling and election sure; for if ye do these things, ye shall never stumble," that is, if you bravely practice good works you will be sure and cannot doubt that God has called and chosen you.” [Sermons of Martin Luther 1:40]
“For if your heart is in the state of faith that you know your God has revealed himself to you to be so good and merciful, without thy merit, and purely gratuitously, while you were still his enemy and a child of eternal wrath; if you believe this, you cannot refrain from showing yourself so to your neighbor; and do all out of love to God and for the welfare of your neighbor. Therefore, see to it that you make no distinction between friend and foe, the worthy and the unworthy; for you see that all who were here mentioned, have merited from us something different than that we should love and do them good. And the Lord also teaches this, when in Luke 6:35 he says: "But love your enemies, and do good unto them, and lend, never despairing; and your reward shall be great, and ye shall be sons of the Most High: for he is kind toward the unthankful and evil." [Sermons of Martin Luther 2.2:101]
“Therefore we must close our eyes, not look at our works, whether they be great, small, honorable, contemptible, spiritual, temporal or what kind of an appearance and name they may have upon earth; but look to the command and to the obedience in the works. Do they govern you, then the work also is truly right and precious, and completely godly, although it springs forth as insignificant as a straw. However, if obedience and God’s commandments do not dominate you, then the work is not right, but damnable, surely the devil’s own doings, although it were even so great a work as to raise the dead...And St. Peter says, Ye are to be as faithful, good shepherds or administrators of the manifold grace of God; so that each one may serve the other, and be helpful to him by means of what he has received, 1 Peter 4:10. See, here Peter says the grace and gifts of God are not one but manifold, and each is to tend to his own, develop the same and through them be of service to others.” [Sermons of Martin Luther 1:244]
In addition, upon hearing that he was being charged with rejection of the Old Testament moral law, Luther responded,
And truly, I wonder exceedingly, how it came to be imputed to me, that I should reject the Law or ten Commandments, there being extant so many of my own expositions (and those of several sorts) upon the Commandments, which also are daily expounded, and used in our Churches, to say nothing of the Confession and Apology, and other books of ours. Martin Luther, ["A Treatise against Antinomians, written in an Epistolary way", http://www.truecovenanter.com/truelutheran/luther_against_the_antinomians.html]
The Westminster Confession of Faith states:
Faith, thus receiving and resting on Christ and His righteousness, is the alone instrument of justification; yet it is not alone in the person justified, but is ever accompanied with all other saving graces, and is no dead faith, but works by love. [Westminster Confession of Faith, CHAPTER XI. Of Justification. http://www.spurgeon.org/~phil/creeds/wcf.htm]
The classic Methodist commentator Adam Clarke held,
The Gospel proclaims liberty from the ceremonial law: but binds you still faster under the moral law. To be freed from the ceremonial law is the Gospel liberty; to pretend freedom from the moral law is Antinomianism.[Adam Clarke Commentary, Gal. 5:13]
Likewise on on Titus 1:16 ("They profess that they know God; but in works they deny, being abominable, and disobedient, and unto every good work reprobate." KJV):
Full of a pretended faith, while utterly destitute of those works by which a genuine faith is accredited and proved. [Adam Clarke Commentary, Titus 1]
To which the Presbyterian commentator Mathew Henry concurs: "There are many who in word and tongue profess to know God, and yet in their lives and conversations deny and reject him; their practice is a contradiction to their profession." [Matthew Henry Complete Commentary on the Whole Bible, Titus 1]
Contemporary evangelical theologian R. C. Sproul writes,
The relationship of faith and good works is one that may be distinguished but never separated...if good works do not follow from our profession of faith, it is a clear indication that we do not possess justifying faith. The Reformed formula is, “We are justified by faith alone but not by a faith that is alone.”[[“Essential Truths of the Christian Faith,” Google books]
Also, rather than the easy believism Rome associates with sola fide, in Puritan Protestantism there was often a tendency to make the way to the cross too narrow, perhaps in reaction against the Antinomian controversy as described in an account (http://www.the-highway.com/Early_American_Bauckham.html) of Puritans during the early American period that notes,
“They had, like most preachers of the Gospel, a certain difficulty in determining what we might call the ‘conversion level’, the level of difficulty above which the preacher may be said to be erecting barriers to the Gospel and below which he may be said to be encouraging men to enter too easily into a mere delusion of salvation. Contemporary critics, however, agree that the New England pastors set the level high. Nathaniel Ward, who was step-son to Richard Rogers and a distinguished Puritan preacher himself, is recorded as responding to Thomas Hooker’s sermons on preparation for receiving Christ in conversion with, ‘Mr. Hooker, you make as good Christians before men are in Christ as ever they are after’, and wishing, ‘Would I were but as good a Christian now as you make men while they are preparing for Christ.’”
Jas 2:17 If it hath not works, is dead - The faith that does not produce works of charity and mercy is without the living principle which animates all true faith, that is, love to God and love to man. — Adam Clarke, LL.D., F.S.A., (1715-1832), Commentary on the Bible
Jas 2:14-18 Even so faith. Faith that has no power to bring one to obedience and to sway the life is as worthless as good wishes which end in words. — The People's New Testament (1891) by B. W. Johnson
Jas 2:17 Even so faith, if it hath not works, is dead, being alone. It is like a lifeless carcass, a body without a soul, Jam. 2:26 for as works, without faith, are dead works, so faith, without works, is a dead faith, and not like the lively hope and faith of regenerated persons: — Dr. John Gill (1690-1771), Exposition of the Entire Bible
“If the works which living faith produces have no existence, it is a proof that faith itself (literally, ‘in respect to itself’) has no existence; that is, that what one boasts of as faith, is dead.” “Faith” is said to be “dead in itself,” because when it has works it is alive, and it is discerned to be so, not in respect to its works, but in respect to itself. — Robert Jamieson, A. R. Fausset and David Brown, Commentary on the Old and New Testaments
Jas 2:17 So likewise that faith which hath not works is a mere dead, empty notion; of no more profit to him that hath it, than the bidding the naked be clothed is to him. — John Wesley
Even so faith; that which they boasted of, and called faith. Is dead; void of that life, in which the very essence of faith consists, and which always discovers itself in vital actings and good fruits, where it is not hindered by some forcible impediment; in allusion to a corpse, which plainly appears to have no vital principle in it, all vital operations being ceased. It resembles a man’s body, and is called so, but in reality is not so, but a dead carcass. — Matthew Poole (1624 -1679)
However, while works justify one having true faith which is counted for righteousness, and manifest that he is fit to be blessed by God under grace, works and one's own holiness are not what actually obtains justification, but in conversion God justifies the unGodly by faith.
In Roman theology, one is formally justified by his own holiness being first "infused" via the act of baptism, and thus he usually ends up having to become good enough once again (and to atone for sins) via postmortem "purifying torments" commencing at death in order to enter Heaven and be with the Lord.
Which is contrary to Scripture , which always places believers with the Lord once absent from this body wherever it clearly speaks of this, even entire churches. And with the only postmortem suffering is that of the loss of rewards (and the Lord's displeasure) at the judgment seat of Christ when He returns. (1Co. 3:8ff) Thanks be to God.
Cathsshould only do (and I should do more of) what Mary and every believer in Scripture did in praying to Heaven, which was to pray directly to the Lord, not saintly secretaries. But they must truly become born again for that.
