Five solae
The five solae of the Protestant Reformation are a foundational set of principles held by theologians and clergy to be central to the doctrine of salvation as taught by the Reformed branches of Protestantism. Each sola represents a key belief in the Lutheran and Reformed traditions in contradistinction to the teaching of the Roman Catholic Church. These Reformers claimed that the Catholic Church, especially its head, the Pope, had usurped divine attributes or qualities for the Church and its hierarchy.
History
The solae were not systematically articulated together until the 20th century; however, sola gratia and sola fide were used in conjunction by the Reformers themselves. For example, in 1554 Melanchthon wrote, "sola gratia justificamus et sola fide justificamur". All of the solae show up in various writings by the Protestant Reformers, but they are not catalogued together by any.In 1916, Lutheran scholar Theodore Engelder published an article titled "The Three Principles of the Reformation: Sola Scriptura, Sola Gratia, Sola Fides". In 1934, theologian Emil Brunner substituted Soli Deo gloriam for Sola Scriptura. In 1958, historian Geoffrey Elton, summarizing the work of John Calvin, wrote that Calvin had "joined together" the "great watchwords". Elton listed sola fide with sola gratia as one term, followed by sola scriptura and soli Deo gloria. Later, in commenting on Karl Barth's theological system, Brunner added Christus solus to the litany of solas while leaving out sola scriptura. The first time the additional two solae are mentioned is in Johann Baptiste Metz's 1965, The Church and the World.
The three solae
In most of the earliest articulations of the solae, three were typically specified: scripture over tradition, faith over works, and grace over merit. Each was intended to represent an important distinction compared with teachings claimed in Catholic doctrine.Sola scriptura ("by Scripture alone")
Sola Scriptura is upheld by Lutheran and Reformed theologies and asserts that scripture must govern over church traditions and interpretations which are themselves held to be subject to scripture. All church traditions, creeds, and teachings must be in unity with the teachings of scripture as the divinely inspired Word of God.Sola Scriptura asserts that the Bible can and is to be interpreted through itself, with one area of Scripture being useful for interpreting others. This principle is largely based on 2 Timothy 3:16, which says, "All scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness." That scripture can interpret itself is a means by which to show the unity of Scripture as a whole. As all doctrines are formed via scriptural understandings, all doctrines must be found to align with Scripture and as such are then subject to scripture before the believer can begin to apply them.
This particular sola is sometimes called the formal principle of the Reformation, since it is the source and norm of the material cause or principle, the gospel of Jesus Christ that is received sola fide, sola gratia. The adjective and the noun are in the ablative case rather than in the nominative case to indicate that the Bible does not stand alone apart from God, but rather that it is the instrument of God by which he reveals himself for salvation through faith in Christ.
Methodist theology, on the other hand, enshrines prima scriptura in its theological concept of the Wesleyan Quadrilateral, which holds that Sacred Tradition, Reason, and Experience are sources of Christian theology, but are subordinate to Sacred Scripture, which is the primary authority.
Sola fide ("by faith alone")
Sola fide, or "by faith alone", asserts that good works are not a means or requisite for salvation. Sola fide is the teaching that justification is received by faith alone, without any need for good works on the part of the individual. In classical Lutheran and Reformed theologies, good works are seen to be evidence of saving faith, but the good works themselves do not determine salvation. Some Protestants see this doctrine as being summarized with the formula "Faith yields justification and good works" and as contrasted with a putative Roman Catholic formula "Faith and good works yield justification." The Catholic side of the argument is based on James 2:14–17. "What does it profit, my brethren, if someone says he has faith but does not have works? Can faith save him? If a brother or sister is naked and destitute of daily food, and one of you says to them, 'Depart in peace, be warmed and filled', but you do not give them the things which are needed for the body, what does it profit? Thus also faith by itself, if it does not have works, is dead." It is even more clear in James 2:24; the only place in scripture where the phrase is used. "See how a person is justified by works and not by faith alone." Likewise, the Methodist Churches also emphasize that ordinarily, both faith and good works play a role in salvation; in particular, the works of piety and the works of mercy, in Wesleyan-Arminian theology, are "indispensable for our sanctification." Bishop Scott J. Jones in United Methodist Doctrine writes that in Methodist theology:In understanding Sola fide, it is important to understand the nuances of difference between Catholic and Lutheran/Reformed notions of the term "justification". Both groups agree that the term invokes a communication of Christ's merits to sinners, not a declaration of sinlessness; Luther used the expression simul justus et peccator. However, Roman Catholicism sees justification as a communication of God's life to a human being, cleansing him of sin and transforming him truly into a son of God, so that it is not merely a declaration, but rather the soul is made actually objectively righteous. The Lutheran and Reformed views of justification, by contrast, are that it is the work of God through the means of grace. Faith is the righteousness of God that is accomplished in us through word and sacraments. Law and gospel work to kill the sinful self and to accomplish the new creation within us. This new creation within us is the faith of Christ. If we do not have this faith, then we are ungodly. Indulgences or human prayers add nothing—they are nothing. Everyone has some kind of faith—usually a faith in themselves. But we need God to continually destroy self-righteous faith and to replace it with the life of Christ. We need the faith that comes from God through law and gospel, word, works and sacraments. In the founding document of the Reformation, the 95 Theses, Luther said that "When our Lord and Master Jesus Christ said, 'Repent' He willed the entire life of believers to be one of repentance" and "And thus be confident of entering into heaven through many tribulations rather than through the false security of peace ".
The true distinction, therefore, between the Lutheran/Reformed and the Catholic view of Justification is not an issue of being "declared righteous" versus being "made righteous", but rather it is the means by which one is justified. In Catholic theology, after the initial conversion which relies solely on the merits of Christ, righteous works are considered meritorious toward salvation in addition to faith, whereas in the Lutheran and Reformed theologies, righteous works are seen as the result and evidence of a truly justified and regenerate believer who has received these by faith alone.
The actual effectual means by which a person receives justification is also a fundamental division between Catholic and Lutheran/Reformed belief. In Catholic theology, conversion effects justification and God gives the baptized the grace of justification : however, the faith required for baptism is not a perfect and mature faith. In baptism, even of infants, the grace of justification and sanctification is "infused" into the soul, making the recipient justified. For the Catholic, baptism functions "ex opere operato" or "by the working of the act", and thus is the efficient and sufficient act to bring about justification, in the case of a child from original sin only, in the case of a believing repentant adult from all sins. For the Lutheran, baptism is a work of God by which the forgiveness of sins and salvation earned by Christ's death, and confirmed by Christ's resurrection, are given to the baptized person who believes God's Word that says He is doing exactly that in baptism.
Infant baptism is not only appropriate, but urged: "We bring the child in the conviction and hope that it believes, and we pray that God may grant it faith; but we do not baptize it upon that, but solely upon the command of God." In the Reformed theologies, especially that of Baptists, however, the faith of the individual is absolutely necessary and is itself the efficient and sufficient response of the individual that effects justification. Therefore, for the Reformed, child baptism is performed on the basis of the promise of faith to come, but Baptists go even further and assert that infant or child baptism is not appropriate nor legitimate. Apart from baptism by water, Catholics also recognize baptism of desire and baptism by blood.
The Sola fide doctrine is sometimes called the material cause or principle of the Reformation because it was the central doctrinal issue for Martin Luther and the other reformers. Luther called it the "doctrine by which the church stands or falls".
Sola gratia ("by grace alone")
Sola gratia, or "only grace", specifically excludes the merit done by a person as part of achieving salvation. Sola gratia is the teaching that salvation comes by divine grace or "unmerited favor" only, not as something merited by the sinner. This means that salvation is an unearned gift from God for Jesus's sake. While some maintain that this doctrine is the opposite of "works' righteousness" and conflicts with some of the aspects of the Roman Catholic doctrine of merit, it might be asserted that this article, taken at face value, conflicts in no way with Roman Catholic teaching. While the doctrine that grace is truly and always a gift of God is held in agreement between both views, the difference in doctrine lies mainly in two facts. First, that of God as sole actor in grace, and second, that man cannot by any action of his own, acting under the influence of grace, cooperate with grace to "merit" greater graces for himself. This doctrine asserts divine monergism in salvation: God acts alone to save the sinner. The responsibility for salvation does not rest on the sinner to any degree as in "synergism".Protestant Arminians, such as Methodists, are synergists but may also claim the doctrine of sola gratia, though they understand it quite differently than Lutherans and Calvinists do. Arminians believe that God saves only by grace and not at all by merit, but man, enabled by what is referred to as "prevenient grace", is enabled by the Holy Spirit to understand the Gospel and respond in faith. Arminians believe that this is compatible with salvation by grace alone, since all the actual saving is done by grace. Arminians believe that humans are only capable of receiving salvation when first enabled to do so by prevenient grace, which they believe is distributed to everyone. Arminians therefore do not reject the conception of sola gratia expounded by Lutheran and Reformed theologians, although their interpretation of it is quite different.
John Owen, in A Display of Arminianism, rejects the implied belief that the understanding of the Reformed theology has any alliance between the two doctrines and Arminianism is but another form of pelagianism, known as semipelagianism.
