Vincent of Lérins

Suspected of semi-Pelagianism, he opposed the Augustinian model of grace and was probably the recipient of Prosper of Aquitaine's Responsiones ad Capitula Objectionum Vincentianarum.

[5] Vincent defended the Marian title of Theotokos (God-bearer) in opposition to the teachings of Patriarch Nestorius of Constantinople, which were condemned by the Council of Ephesus.

[6] Gennadius of Massilia wrote that Vincent died during the reigns of the Roman Emperor Theodosius II in the East and Valentinian III in the West.

[7] Caesar Baronius included his name in the Roman Martyrology, but Louis-Sébastien Le Nain de Tillemont doubted whether there was sufficient reason.

Vincent wrote his Commonitory to provide himself with a general rule to distinguish Catholic truth from heresy, committing it to writing as a reference.

"[8]: 132 [9]: 10  The currently accepted idea that Vincent was a semi-Pelagian is attributed to a 17th-century Protestant theologian, Gerardus Vossius, and developed in the 17th century by Cardinal Henry Noris.

It is a matter of academic debate whether Vincent is the author of the Objectiones Vincentianae, a collection of sixteen inferences allegedly deduced from Augustine's writings, which is lost and only known through Prosper of Aquitaine's rejoinder, Responsiones ad capitula objectionum Vincentianarum.
