He was not the kind who started revolutions, but the kind who brought order to the ensuing chaos. His mentor, Martin Luther, was brash, impulsive, and forceful. But Philip Melanchthon was a timid, sober-minded unifier. Luther, by his own admission, was “substance without words,” while his brilliant young disciple was “substance and words.”

Luther had little concern for precision or guarding against misconception; Melanchthon made nuance his forte. Luther said he used a spear, while Melanchthon used pins and needles. Luther was a pioneer, hacking his way through centuries of superstitious brush with an apostolic machete. But Melanchthon, like Bullinger in Zurich and Calvin in Geneva, played the part of the calm, collected systematic, grading the Protestant path for generations to come.

He was “the quiet reformer” — and a fitting complement to the loud, boisterous Luther. But not only was Melanchthon known as quiet and peaceful, but on occasion he demonstrated an explosive temper. And not only was he relentlessly curious, and a master of many subjects, but he also was strangely superstitious. Like every sinner, he was his own inconsistent blend of virtue and vice, and God was willing to work with that.

Prodigy, Professor, Copilot

A child prodigy, Melanchthon studied the classics in Heidelberg and Tubingen, and arrived in Wittenberg in 1519, at age 22, just as the Reformation was heating up. That same year, he accompanied Luther as an aid to the Leipzig Disputation. By 1521, he published the first edition of his Loci Communes(“basic concepts”) which started as a commentary on Romans and sought to tie Christian theology, inspired by Luther, to the biblical text, rather than the philosophical categories of medieval scholarship.

As the fires of reform raged, Melanchthon was there at Luther’s side in 1529 at Marburg, and there in Luther’s stead in 1530 at Augsburg, where he represented the Lutheran cause — and even drafted the Augsburg Confession — since Luther was an outlaw and unable to attend.

Independent Mind

Melanchthon was too careful a thinker to agree with Luther on everything. But even as differences emerged, he always thought of himself as Luther’s disciple. He was helping his mentor, not rebelling against him, in maturing his theological insights.

His two key divergences with Luther, for which some detractors would relentlessly take him to task, pertained to the bondage of the will and the Lord’s Supper. As early as 1540, a decade after Augsburg, and six years before Luther’s death, Melanchthon went public, in an updated version of the confession, with an iterated view of the Table. His opponents accused him of being a crypto-Calvinist on the Eucharist; however, in the other key divergence, he clearly moved away from Geneva. Melanchthon rejected double predestination, which he thought a necessary entailment of Luther’s view of the will, and suspected that at least some of Luther’s followers were going too far in their sense of the will’s bondage.

Leader of the Lutherans

In the final tally, Melanchthon became the intellectual leader of the Lutherans. Not only was he the first systematic theologian of the Reformation, and one of its most significant figures, but he designed educational systems that gave Lutheranism staying power not just in his unstable days but in the even more turbulent times to come. God put Melanchthon’s gifts, quirks, and even inconsistencies to good use to reinforce Reformation theology as a world-changing force.
