Third Council of Orléans

The third council of national stature, or third Council of Orléans, was a synod of the Catholic bishops of France. It opened around 7 May 538 and was presided over by Loup, Archbishop of Lyon. It established mainly:
 * Sunday as day of the Lord;
 * prohibition of field work on Sundays;
 * prohibition of clerics practicing usury;
 * prohibition of the conjuring of priests, as a critic of their bishop (canon 24, recall of canon 18 of the Council of Chalcedon, 451).
 * The bishop must redeem a Christian slave in the service of a Jew if he takes refuge in the church, while the constitutions of the Lower Roman Empire demanded to return them to their master, without further guarantees.

A conciliabule, of which we do not know the subject, took place in Orleans in 540.
