The First Council of Toledo was held at Toledo, Spain, in September of 400.[1][2] The council was assembled under Archbishop Patronus with its primary purpose to condemn the Priscillian heresy, to receive back Priscillians, and uphold the Nicene Creed.[1][2] Eighteen other Hispanic bishops participated,[2] including Lampius, bishop of Barcelona.[3] Many Priscillians were readmitted into the Catholic Church, notably Priscillian bishop Dictinnius.[4] The council also reformed the clergy.[5] Twenty canons were published by this council.[1][2] It would be another 47 years before a council met again in Toledo.[6]
