From BiblePortal Wikipedia
Catharists [1]
A sect that spread much in the Latin church in the twelfth century. Their religion resembled the doctrine of the Manichaeans and Gnostics (see those articles.) They supposed that matter was the source of evil; that Christ was not clothed with a real body; that baptism and the Lord's supper were useless institutions; with a variety of other strange notions.
