My theme is alwey oon, and evere was –
Radix malorum est Cupiditas.
– Geoffrey Chaucer
The Canterbury Tales, The Pardoner’s Prologue. When the Pardoner preaches in church, his theme is always "Radix malorum est Cupiditas" (Latin biblical quotation meaning "greed is the root of all evil" – 1 Timothy 6:10). The problem with this is the Pardoner himself is greedy, and simply wants to make money rather than help his flock. So he is the arch-hypocrite.
