Council of Sens

Held in 600[citation needed] or 601,[1] this council condemned simony in conformity with the instructions of Pope St Gregory the Great.

St Columbanus refused to attend to prevent the possible enactment of a French resolution of the debate concerning the date of Easter then dividing the Frankish and Breton churches.

A series of councils were held in 657,[2] 669 or 670,[citation needed] 833,[1] 845[1] or 846, 850, 852, 853, 862, 980, 986, 996, 1048, 1071, and 1080, mostly concerned with the privileges of the Abbey of St Pierre le Vif.

Attended by King Louis VII and Archbishop Samson of Reims, it was used by St Bernard of Clairvaux as an opportunity to condemn Peter Abelard for Arianism in distinguishing the members of the Trinity; for Pelagianism in preferring free will to grace; and Nestorianism in dividing the human and divine natures of Jesus Christ.

Rather than submit to this, Abelard published an apology confessing orthodox beliefs, desisting from his appeal, and retracting all he had written "contrary to the truth".

It noted bishops should provide a 40-day indulgence to those fasting on the eve of the Feast of Corpus Christi; directed that jurisdictions were clerics were forcibly detained should be placed under interdict; and condemned priests with beards, long hair, or boots dyed red, green, yellow, or white.
