[7] Hypothetical universalist teachings may be found in the writings of early Reformed theologians including Heinrich Bullinger, Wolfgang Musculus, Zacharias Ursinus, and Girolamo Zanchi.
[8] Moses Amyraut, originally a lawyer, but converted to the study of theology by the reading of Calvin's Institutes of the Christian Religion, an able divine and voluminous writer, developed the doctrine of hypothetical or conditional universalism, for which his teacher, John Cameron (1580–1625), a Scot, and for two years headmaster of Saumur Academy, had prepared the way.
Being employed by the Reformed Synod in important diplomatic negotiations with the government, he came in frequent contact with bishops, and with Cardinal Richelieu, who esteemed him highly.
Amyraut maintained the Calvinistic premises of an eternal foreordination and foreknowledge of God, whereby he caused all things to pass, the good efficiently, the bad permissively.
Jean Daillé (1594–1670), David Blondel (1591–1655), and others considered it innocent and consistent with the decrees of the Synod of Dort, where German Reformed and Anglican delegates professed similar views against the supralapsarianism of Gomarus.
In this way hypothetical universalism was sanctioned as a permissible view, along with the particularism that had characterized historic Reformed orthodoxy, and a schism in the French Church was avoided.
The literary controversy continued for several years longer and developed a large amount of learning and ability, until it was brought to an abrupt close by the political oppressions of the Reformed Church in France.
Repentance and faith, being obedience to this law, are the believer's personal saving righteousness… the fruit of the seeds which Baxter sowed was neonomian Moderatism in Scotland and moralistic Unitarianism in England.
"[14] Popularised in England by the Reformed pastor Richard Baxter, Amyraldism also gained strong adherence among the Congregationalists and some Presbyterians in the American colonies, during the 17th and 18th centuries.
In Australia, many in the Anglican Diocese of Sydney hold to a modified "four point" Calvinism, while in England, one author, Dr. Alan Clifford, pastor of the Norwich Reformed Church, tirelessly promotes Amyraldism in self-published pamphlets such as Amyraut Affirmed.
Amyraldism has been strongly criticized in recent years by contemporary Calvinist theologians who argue that one cannot accept that Christ died for all people in the world if not all are saved.
