Philip Melanchthon
Philip Melanchthon (born Philipp Schwartzerdt; 16 February 1497 – 19 April 1560) was a German Lutheran reformer, collaborator with Martin Luther, the first systematic theologian of the Protestant Reformation, intellectual leader of the Lutheran Reformation, and an influential designer of educational systems. He stands next to Luther and John Calvin as a reformer, theologian, and molder of Protestantism. After Luther himself, he is the primary founder of Lutheranism.
List of Reformed denominations
The German Reformed Church, unusually, does not trace its origins back to Zwingli or Calvin, but rather to Philipp Melanchthon, Luther's best friend and closest ally. After Melanchthon's death in 1560, extremist Lutherans (from whom Luther had previously distanced himself) accused Melanchthon's successors in the "Philippist" cause of Crypto-Calvinism and mercilessly persecuted and sometimes killed them in several states, especially Saxony. Other states, such as Hesse(-Cassel), remained openly Philippist and Reformed. Only during the time of Calvin (1509–1564) himself did genuinely Calvinist influences enter the German Reformed faith; even today, it remains more Philippist than Calvinist.
