Lucidus a presbyter in the Gallic Church in the 5th century, was one of the most distinguished members of the ecclesiastical party which in that period defended the doctrines of St. Augustine against Semi-Pelagianism then greatly preponderating in the Church. The views of Lucidus are to be ascertained from the works resulting from the controversy between himself and Faustus of Rieg, who obliged him to recant. The latter wrote against Lucidus his Fausti Rejensis epistola ad Lucidum, and the recantation of Lucidus — probably posterior to the Synod of Aries, 475, as indicated by the expression, "Juxta praedicandi recentia statuta concilii damno vobiscum sensum ilium," etc. — is entitled Lucidi errorem emendantis libellus ad episcopos. In some respects Lucidus, indeed, had gone further than St. Augustine himself, especially in regard to predestination. allowing no free agency to man, and making all the workings of human conscience to be but the effects of the immediate and gratuitous influence of God. Such, at least, is the accusation which was brought against him at the Council of Aries. The text of his recantation is to be found in all the Bibl. Patr. and in the collections of councils.
