Calvinism, also called Reformed Christianity, is a major branch of Protestantism that follows the theological tradition and forms of Christian practice set down by John Calvin and various other Reformation-era theologians. It emphasizes the sovereignty of God and the authority of the Bible.
Original sin is the Christian doctrine that holds that humans, through the fact of birth, inherit a tainted nature with a proclivity to sinful conduct in need of regeneration. The biblical basis for the belief is generally found in Genesis 3, in a line in Psalm 51:5, and in Paul's Epistle to the Romans, 5:12-21.
Justificatio sola fide, meaning justification by faith alone, is a soteriological doctrine in Christian theology commonly held to distinguish the Lutheran and Reformed traditions of Protestantism, among others, from the Catholic, Eastern Orthodox, Oriental Orthodox, Assyrian and Anabaptist churches. The doctrine asserts that it is on the basis of faith that believers are made right of their transgressions of divine law rather than on the basis of what Paul the Apostle calls "works of the law", sometimes called good works. This forgiveness is known as "justification". In classical Lutheran and Reformed theologies, works are seen as crucial evidence of faith, but the works themselves do not determine salvation. In contrast, Methodist doctrine affirms a belief in justification by faith that offers God's forgiveness, but holds that holy living with the goal of Christian perfection (sanctification) is essential for salvation. Anabaptist theology categorically rejects the Lutheran and Reformed doctrine of sola fide, and instead emphasizes a "faith that works"; Anabaptists teach that "justification begun a dynamic process by which the believer partook of the nature of Christ and was so enabled to live increasingly like Jesus."
In Western Christian theology, grace is created by God who gives it as help to one because God desires one to have it, not necessarily because of anything one has done to earn it. It is understood by Western Christians to be a spontaneous gift from God to people – "generous, free and totally unexpected and undeserved" – that takes the form of divine favor, love, clemency, and a share in the divine life of God. In the Eastern Orthodox Church, grace is the uncreated Energies of God. Among Eastern Christians generally, grace is considered to be the partaking of the Divine Nature described in 2 Peter 1:4 and grace is the working of God himself, not a created substance of any kind that can be treated like a commodity.
In Christianity, salvation is the saving of human beings from sin and its consequences—which include death and separation from God—by Christ's death and resurrection, and the justification entailed by this salvation.
In Christian theology, justification is the event or process by which sinners are made or declared to be righteous in the sight of God.
Sanctification literally means "to set apart for special use or purpose", that is, to make holy or sacred. Therefore, sanctification refers to the state or process of being set apart, i.e. "made holy", as a vessel, full of the Holy Spirit of God. The concept of sanctification is widespread among religions, including Judaism and especially Christianity. The term can be used to refer to objects which are set apart for special purposes, but the most common use within Christian theology is in reference to the change brought about by God in a believer, begun at the point of salvation and continuing throughout the life of the believer. Many forms of Christianity believe that this process will only be completed in Heaven, but some believe that complete holiness is possible in this life.
Prevenient grace is a Christian theological concept that refers to the grace of God in a person's life which precedes and prepares to conversion. The concept was first developed by Augustine of Hippo (354–430), was affirmed by the Second Council of Orange (529) and has become part of Catholic theology. It is also present in Reformed theology, through the form of an effectual calling leading some individuals irresistibly to salvation. It is also in Arminian theology, according to which it is dispensed universally in order to enable people to respond to the offer of salvation, though it does not ensure personal acceptance.
Imparted righteousness, in Methodist theology, is that gracious gift of God given at the moment of the new birth which enables a Christian disciple to strive for holiness and sanctification. John Wesley believed that imparted righteousness worked in tandem with imputed righteousness. Imputed righteousness is the righteousness of Jesus credited to the Christian, enabling the Christian to be justified; imparted righteousness is what God does in Christ by the power of the Holy Spirit after justification, working in the Christian to enable and empower the process of sanctification.
Imputed righteousness is a concept in Christian theology proposing that the "righteousness of Christ...is imputed to [believers]—that is, treated as if it were theirs through faith." It is on the basis of Jesus' righteousness that God accepts humans. This acceptance is also referred to as justification.
Peter Taylor Forsyth, also known as P. T. Forsyth, (1848–1921) was a Scottish theologian.
The theology of the Cross or staurology is a term coined by the German theologian Martin Luther to refer to theology that posits "the cross" as the only source of knowledge concerning who God is and how God saves. It is contrasted with the "theology of glory", which places greater emphasis on human abilities and human reason.
Free will in theology is an important part of the debate on free will in general. Religions vary greatly in their response to the standard argument against free will and thus might appeal to any number of responses to the paradox of free will, the claim that omniscience and free will are incompatible.
The theology of Martin Luther was instrumental in influencing the Protestant Reformation, specifically topics dealing with justification by faith, the relationship between the Law and Gospel, and various other theological ideas. Although Luther never wrote a systematic theology or a "summa" in the style of St. Thomas Aquinas, many of his ideas were systematized in the Lutheran Confessions.
Penal substitution is a theory of the atonement within Protestant Christian theology, which declares that Christ, voluntarily submitting to God the Father's plan, was punished (penalized) in the place of sinners (substitution), thus satisfying the demands of justice so God can justly forgive sins making us at one with God (atonement). It began with the German Reformation leader Martin Luther and continued to develop within the Calvinist tradition as a specific understanding of substitutionary atonement. The penal model teaches that the substitutionary nature of Jesus' death is understood in the sense of a substitutionary fulfilment of legal demands for the offenses of sins.
In its widest sense, the phrase union with Christ refers to the relationship between the believer and Jesus Christ. In this sense, John Murray says, union with Christ is "the central truth of the whole doctrine of salvation." The expression "in Christ" occurs 216 times in the Pauline letters and 26 times in the Johannine literature. Hence, according to Albert Schweitzer, "This 'being-in-Christ' is the prime enigma of the Pauline teaching: once grasped it gives the clue to the whole." Given the large number of occurrences and the wide range of contexts, the phrase embodies a breadth of meaning.
The term Protestant ecclesiology refers to the spectrum of teachings held by the Protestant Reformers concerning the nature and mystery of the invisible church that is known in Protestantism as the Christian Church.
Sola gratia, meaning by grace alone, is one of the five solae and consists in the belief that salvation comes by divine grace or "unmerited favor" only, not as something earned or deserved by the sinner. It is a Christian theological doctrine held by some Protestant Christian denominations, in particular the Lutheran and Reformed traditions of Protestantism, propounded to summarise the Protestant Reformers' basic soteriology during the Reformation. In addition, salvation by grace is taught by the Catholic Church: "By the grace of God, we are saved through our faith; this faith entails by its very nature, good works, always enabled by prior grace, without which this faith is dead."
The two kinds of righteousness is a Lutheran paradigm. It attempts to define man's identity in relation to God and to the rest of creation. The two kinds of righteousness is explicitly mentioned in Luther's 1518 sermon entitled "Two Kinds of Righteousness", in Luther's Commentary on the Epistle to the Galatians (1535), in his On the Bondage of the Will, Melanchthon's Apology of the Augsburg Confession, and in the third article of the Formula of Concord. It is also the implicit presupposition governing Luther's On the Freedom of a Christian as well as other works.
