Philip Melanchthon played a key role in the academic and theological reforms in Wittenberg. He also wrote the Augsburg Confession and the Apology to the Confession
August 18, 1520: Philipp Melanchthon married Katharina Krapp in Wittenberg. Katharina was the daughter of Hans Krapp who was the highly esteemed mayor of Wittenberg.
Apparently, Philipp had been determined to live his life as a bachelor. He was fully dedicated to his work and was afraid that domestic life would hinder his teaching and research. His friends, including Martin Luther, totally disagreed. While Luther at this time was avoiding marriage for himself, he realized that a wife was exactly what his friend and colleague needed. He helped to arrange the marriage and was a strong supporter of it.
Philipp and Katharina’s marriage was a happy one. Katharina proved to be a strong support for her husband both emotionally and physically. She stood by him when he faced opposition from the other reformers and nursed him when he was ill.
Philipp and Katharina had four children: Anna, Philipp, Georg, and Magdalene.
For reasons that remain unclear, Katharina and Katie Luther never became good friends. It seems that the Melanchthons initially disapproved of Martin and Katie’s marriage. Speculation has also been raised as to whether Katharina, who was born in a higher social class than Katie, resented a former nun now rising above her socially. The rift was obviously mended between Philipp and the Luthers and the Melanchthon and Luther children were playmates. But the Katies never became close despite all that they had in common.
Katharina Melachthon died in 1557 while Philipp was in Heidelberg furthering the cause of the Reformation.
