Luther’s declining influence, 1530–46: Philip Melanchthon’s codification…

The idea

After 1530 Luther’s direct influence declined as others systematised Lutheran belief. Melanchthon’s Loci Communes (1521) was the first Protestant theology textbook, later expanded to codify Lutheran doctrine. The Augsburg Confession (1530), written by Melanchthon, presented Lutheran beliefs to Charles V; it became a key statement of faith and showed a moderate, negotiated position. Meanwhile, Catholic and Lutheran beliefs diverged sharply on justification, the sacraments, papal authority and Scripture. In 1540 Luther reluctantly approved Philip of Hesse’s bigamous marriage to Margarete von der Saale, damaging his moral authority. These developments left Lutheranism more defined but less dependent on Luther personally.

What earns the marks

• Explains how Melanchthon’s Loci Communes (1521) codified Lutheran beliefs, moving from Luther’s polemical works to a systematic theology.
• Describes the Augsburg Confession (1530) as a statement of Lutheran faith presented to Charles V, and assesses its importance for legal recognition and unity.
• Analyses growing divergence between Catholic and Lutheran beliefs on justification, the number and nature of sacraments, papal authority and the authority of Scripture.
• Explains how the Philip of Hesse affair (1540) damaged Luther’s reputation and contributed to his declining personal influence.
• Evaluates the relative importance of Melanchthon’s codification, the Augsburg Confession and the Philip of Hesse affair in explaining Luther’s declining influence.

Common mistakes and how to put them right

• Thinking the Loci Communes was written in 1530.

  Put it right: It was first published in 1521 and later expanded.

• Assuming Luther wrote the Augsburg Confession.

  Put it right: Melanchthon was its principal author, though Luther approved it from Coburg.

• Believing the Philip of Hesse affair was a divorce.

  Put it right: It was a bigamous marriage, which Luther reluctantly sanctioned.

• Treating Luther’s declining influence as total disappearance.

  Put it right: His ideas remained central, but leadership passed to figures like Melanchthon.

Exam tips

• For ‘declining influence’, distinguish between Luther’s personal authority and the institutional strength of Lutheranism.
• Use the Augsburg Confession to show both codification and political negotiation with the Emperor.
• Link the Philip of Hesse affair to contemporary criticisms of Luther’s judgement, not just to scandal.
