Responding to rumours prompted by the marriage of Martin Luther, in a letter to François Dubois (13 March 1526), as translated in The Correspondence of Erasmus : Letters 1658 to 1801, January 1526-March 1527 (1974) edited by Charles Garfield Nauert and Alexander Dalzell, p. 79
Paraphrased variant: They say that the Antichrist will be born of a monk and a nun. If so, there must already be thousands of Antichrists.
Context: There is no doubt about Martin Luther's marriage, but the rumour about his wife's early confinement is false; she is said however to be pregnant now. If there is truth in the popular legend, that Antichrist will be born from a monk and a nun (which is the story these people keep putting about), how many thousands of Antichrists the world must have already!
