The Commonitorium or Commonitory is a 5th-century Christian treatise written after the council of Ephesus under the pseudonym "Peregrinus" and attributed to Vincent of Lérins. It is known for Vincent's famous maxim: "Moreover, in the Catholic Church itself, all possible care must be taken, that we hold that faith which has been believed everywhere, always, by all."

*De Vocatione Omnium Gentium* is a theological treatise devoted to the difficult relationship between divine grace, human freedom, election, and God’s will that all men should be saved. Beginning from the controversy over whether the primacy of grace abolishes free will, the work argues that grace does not destroy human volition but heals, directs, and perfects it, while every genuinely salvific good ultimately originates in God. Through sustained engagement with Scripture, it examines the meaning of universal biblical expressions concerning salvation, the distinction between general and special gifts of grace, the mysterious diversity of God’s dealings with peoples and individuals, and the gradual calling of the nations into the Church. Particular attention is given to the history of salvation, from the earliest ages and Israel’s election to the worldwide preaching of the Gospel, while repeatedly insisting that the hidden reasons for divine election and the differing times of vocation remain beyond human scrutiny. The result is a careful attempt to uphold simultaneously the universality of God’s saving goodness, the necessity and gratuity of grace, human responsibility, and reverence before the inscrutable judgments of divine providence.

Liber contra Collatorem is a theological treatise by St. Prosper of Aquitaine written in defense of St. Augustine’s doctrine of grace against the views associated with John Cassian’s thirteenth Conference. Prosper examines a series of propositions concerning grace, free will, the origin of good intentions, merit, perseverance, and human cooperation with divine assistance, arguing that Cassian’s position departs from Catholic teaching whenever it attributes the beginnings of saving willing or action to unaided human nature. Throughout the work, he appeals extensively to Scripture, ecclesiastical authority, conciliar decisions, and earlier anti-Pelagian controversies, presenting Augustine’s theology as continuous with the doctrinal judgments of the Church. The treatise culminates in a systematic recapitulation of Cassian’s principal definitions and a broader defense of the primacy of divine grace in every stage of the Christian life, while affirming that grace does not abolish human freedom but restores, directs, and strengthens it.
