“ TOLEDO, COUNCILS OF (Concilia toletana) . From the 5th to the 16th century about thirty synods, variously counted, were held at Toledo in Spain. The earliest, directed against Priscillianism, assembled in 400. The “third” synod of 589 marked the epoch-making conversion of King Reccared from Arianism to Roman Catholicism. The “fourth,” in 633, probably under the presidency of the noted Isidore of Seville, regulated many matters of discipline, decreed uniformity of liturgy throughout the kingdom and took stringent measures against baptized Jews who had relapsed into their former faith. ”
