It was at this time he began his memorable controversy with Episcopius, who, in attacking the Coronis, railed against the author as having been "a disturber of the public peace in his native country, so that the English magistrates had banished him thence; and now, by his late printed Coronis, he was raising new disturbances in the peaceable Netherlands."
Subsequently Ames entered into a controversy in print with Grevinchovius on universal redemption and election, and cognate problems. He brought together all he had maintained in his Coronis ad Collationem Hagiensem - his most masterful book, which figures largely in Dutch church history.
