That word doesn't seem to have much meaning to Catholics. They mistranslate it penance and preach penance to earn forgiveness of sins.
Considering the lifestyle I've sen the vast majority of Catholics lead, repentance is not part of their vocabulary. Just go to confession and your good to go.
Jesus calls to conversion. This call is an essential part of the proclamation of the kingdom: "The time is fulfilled, and the kingdom of God is at hand; repent, and believe in the gospel."
