Martin Luther wasn’t prone to compromise. He famously said in his sermon “Knowledge of God’s Will and Its Fruit”:
The world at the present time is sagaciously discussing how to quell the controversy and strife over doctrine and faith, and how to effect a compromise between the Church and the Papacy. Let the learned, the wise, it is said, bishops, emperor and princes, arbitrate.
