Councils of Toledo (
Concilia toletana). From the 5th century to the 7th century AD, about thirty
synods, variously counted, were held at
Toledo in what would come to be part of
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 orthodox
Chalcedonian Christianity. 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. The
British Celts of Galicia accepted the Latin rite and stringent measures were adopted against baptized Jews who had gone back to their former faith. The
"twelfth" council in 681 assured to the
archbishop of Toledo the primacy of
Hispania (present
Iberian Peninsula). As nearly one hundred early
canons of Toledo found a place in the
Decretum Gratiani, they exerted an important influence on the development of
ecclesiastical law.
