The five solae are the five foundational "alones" of the Protestant Reformation, each expressing a non-negotiable biblical conviction:
Sola Scriptura โ Scripture Alone: The Bible is the supreme and final authority in all matters of faith and practice. Tradition, councils, and popes are subordinate to Scripture.
Sola Fide โ Faith Alone: Justification is received through faith alone, not through works, merit, or sacramental participation. "A man is justified by faith apart from works of the law" (Romans 3:28).
Sola Gratia โ Grace Alone: Salvation is entirely God's gracious gift; human will contributes nothing to regeneration or justification.
Solus Christus โ Christ Alone: Christ is the only mediator between God and man; no saints, priests, or Mary supplement His mediation.
Soli Deo Gloria โ Glory to God Alone: The ultimate purpose of all things is the glory of God alone โ not human merit, papal authority, or church prestige.
The five solae are not found as a formal list in Webster 1828, but the concepts are thoroughly Reformation and Puritan. Webster's own evangelical Calvinist faith was shaped by these principles. Sola Scriptura in particular was the regulative principle behind the Puritan project of reforming both church and commonwealth by Scripture alone. The solae represent the distillation of the Reformers' reading of Paul's epistles โ particularly Romans and Galatians.
Sola Scriptura is corrupted into solo scriptura โ "just me and my Bible" with no tradition, no confessions, no community hermeneutic. This produces theological individualism and instability.
Sola Fide is corrupted into antinomianism โ faith without works, as if justification negates the need for sanctification (see Antinomianism).
Sola Gratia is corrupted into fatalism โ if God saves whom He will, why evangelize?
Solus Christus is eroded by Marian devotion, saint intercession, and pastoral authority elevated above Scripture.
Soli Deo Gloria is the first to fall in consumer Christianity โ where the church exists to serve the felt needs of the congregation, not the glory of God.

The five Reformation watchwords (as Latin shorthand):
Sola Scriptura โ Scripture alone (Luther, 1517+)
Sola Fide โ faith alone (Luther: "by this the church stands or falls")
Sola Gratia โ grace alone
Solus Christus โ Christ alone (solus = masc. form)
Soli Deo Gloria โ glory to God alone (soli = dative masc.)
pistis (ฯฮฏฯฯฮนฯ, G4102) โ faith, trust, belief; the instrument of justification in Sola Fide.
charis (ฯฮฌฯฮนฯ, G5485) โ grace, unmerited favor; the source of salvation in Sola Gratia.
graphฤ (ฮณฯฮฑฯฮฎ, G1124) โ Scripture, writing; the supreme authority in Sola Scriptura (2 Tim 3:16; 2 Pet 1:20โ21).
• Romans 3:28 — "For we hold that one is justified by faith apart from works of the law." (Sola Fide)
• Ephesians 2:8โ9 — "By grace you have been saved through faith...not a result of works." (Sola Gratia / Sola Fide)
• 2 Timothy 3:16โ17 — "All Scripture is breathed out by God and profitable...that the man of God may be complete." (Sola Scriptura)
• 1 Timothy 2:5 — "There is one mediator between God and men, the man Christ Jesus." (Solus Christus)
• Romans 11:36 — "From him and through him and to him are all things. To him be glory forever." (Soli Deo Gloria)
• "Luther said Sola Fide is the article by which the church stands or falls โ get it wrong and you have a different gospel entirely."
• "Sola Scriptura is not anti-tradition โ it is tradition held accountable to a higher authority."
• "The five solae are not five separate doctrines โ they are five facets of one gem: the gospel of sovereign grace."
