Romans believed that Lucifer, initially a good creature would have revolted against his god. Thereby, the evil would have been born from the free referee of the devil, and a second time from the free-referee of the man.
Cathares didn't understand how a creature could react against his own creator and made the main argument of it.
By this point of view, they wanted to prove that there was a bad principle and that the free-referee didn't make any sense.

Here are the 7 principles forming the dialectical basis of the dualistic heresy.
According to René Nelli : " the cathare phenomena " Privat editions

* God was very powerful in the good and eternity, but
* There was existing a root of the evil, which destroyed any originally good will
* The principle of the evil (devil/bad) was only nihil (nothing), or at least only " half of being " and that :
* It could only appear in the mixture.
* True God had created everything from his own substance, and not from the nihil.
* Creation was coeternal with the creator.
* The creature didn't have any freedom.

The main idea is the mixture.

Cathare do not await from death an automatic delivery of their soul. The soul can enter to the kingdom of the good only if it finds its original purity.

Saving knowledge is received with the baptism by laying on the hands and by the spirit, this is the CONSOLAMENTUM..

The consolamentum was a collective and solemn ceremony, given after one year of probationary period, to check the faith of the beginner. Then, a cathare bishop remitted to the beginner "the new will" book. This person became "perfect" or "pure" and thereby could preach his faith, like a priest would do it today, but in a different way.

At the end of the ceremony, all the perfect ones pronounced this sentence:
" Holy Father, receive your servant in your justice, and send your grace and your Holy Spirit on him (the beginner) ".

The perfect one had to comply with very strict rules of life:

* prohibition to kill.
* abstention from any sexual relation.
* do not to lie.
* never steal nor breach.
* Taking of oath was forbidden.
* do not to blaspheme nor curse.
* no meat, cheese or eggs.
* to commit oneself to suffer from hunger, thirst, insults and persecutions without any complaints.
