Joscelin bishop of Soissons, a rival of Abelard, and one of the most distinguished teachers in Paris, was born in the latter part of the 11th century. In 1115 he became archdeacon of Soissons, and in 1126 succeeded Lisiard as bishop of that see. He took part in the councils of Troyes and Rouen, and in the coronation of king Philip. In 1131 Innocent II sent him, together with St. Bernard, on a mission to the archbishop and to the count of Bordeaux. On his return in 1132 he founded the abbey of Longpont. In 1140 he was one of the judges of Abelard at the Council of Sens, and at the Council of Paris in 1147 was commissioned to inquire into the propositions attributed to Gilbert de la Porrée. He died Oct. 25, 1152. Joscelin enjoyed great reputation for learning and wisdom, and in his diocese fulfilled all the duties of his charge with scrupulous faithfulness. He wrote an Expositio symboli and an Expositio Orationis Dominicoe, both of which were published in Martene and Durand's Amplissima Collectio, 9, 1101, 1111, Martene, Anecdota, p. 434, gives also two of his letters.
