Joachim Westphal accused Melanchthon of agreement with John Calvin, and from this time the Philippists rested under the suspicion of Crypto-Calvinism. The more the German Lutherans entertained a dread of the invasion of Calvinism, the more they mistrusted every announcement of a formula of the Lord's Supper after the form of Luther's doctrine yet obscure.
Joachim Westphal accused Melanchthon of supporting John Calvin, leading to suspicion that Philippists were secretly Calvinist. As German Lutherans grew fearful of Calvinism, they became suspicious of any new formulas for the Lord's Supper, even if they were based on Luther's teachings but hidden in secrecy.
