Charles François d'Abra de Raconis

At this epoch he took part in religious polemics and wrote works of controversy, anti-Calvinist and anti-Jansenist pamphlets.

His Summa totius philosophiae was published in 1617 and later developed in the Metaphysica seu prima ac suprema scientia (Paris, 1624).

Two years before his death he published his "Examen et jugement du livre de la fréquente communion fait contre la fréquente communion et publié sous le nom du sieur Arnauld" (Paris, 1644).

Raconis also wrote against the heresy of "two heads of the Church Saints Peter and Paul," formulated by Martin de Barcos.

The bishop's "Primauté et Souveraineté singulière de Saint Pierre" (1645) roused the wrath of his opponents.
