Reformation Theology
An in-depth analysis of the Protestant Reformation's theological foundations, tracing the doctrinal contributions of Luther, Calvin, Zwingli, and other key reformers. This study examines sola scriptura, sola fide, and their lasting impact on Western Christian thought and ecclesiology.
"Here I stand. I can do no other. God help me."
— Martin Luther, Diet of Worms (1521)
The Five Solae
The Protestant Reformation produced a set of theological watchwords — the Five Solae — that crystallized the reformers' departures from medieval Roman Catholic doctrine: sola scriptura (Scripture alone), sola fide (faith alone), sola gratia (grace alone), solus Christus (Christ alone), and soli Deo gloria (glory to God alone).
Luther's 1517 Ninety-Five Theses launched a controversy that rapidly spread through Europe, catalyzed by the printing press, and ultimately produced enduring confessional traditions including Lutheranism, Reformed theology, and Anglicanism.
