What was the Reformation about?
“A cesspool of heresies.” This was the judgment rendered by Holy Roman Emperor Charles V on May 26, 1521, shortly after Luther took a stand at the Diet of Worms. Earlier, in the bull Exsurge Domine, Pope Leo X described Luther as a wild boar loose in the vineyard of Christ and as a stiff-necked, notorious, damned heretic. On May 4, 1521, Luther was “kidnapped” by friends and whisked off to Wartburg castle, where he was kept secretly hidden, disguised as a knight. There Luther immediately undertook the task of translating the Bible into the vernacular. Frequently the Reformation is described as a movement that revolved around two pivotal issues. The so-called “material” cause was the debate over sola fide (“justification by faith alone”). The “formal” cause was the issue of sola Scriptura, that the Bible and the Bible alone has the authority to bind the conscience of the believer. Church tradition was regarded with respect by the Reformers but not as a normative source of revelation.
