Morel, Claude a French theologian and preacher of note, flourished in the 17th century. He was a doctor of the Sorbonne and court preacher, but is best known as a passionate adversary of the Jansenists. He published against them La conduite de Saint Augustin contre les Pelagiens (1658), and L'Oracle de la Velrite, ou l'Eglise de Dieu contre toutes sortes d'heresies (1666). The Jansenists failed not to answer him, as four pieces still attest, viz. a Latin epistle in prose, two pieces in Latin verse inveighing against him, and a French sonnet. In 1659 the council of state instituted proceedings against these Jansenistic opponents and sentenced them.
