Canon 1 made clear there was only:
...one universal church of the faithful, outside of which nobody at all is saved, in which Jesus Christ is both priest and sacrifice. His body and blood are truly contained in the sacrament of the altar under the forms of bread and wine, the bread and wine having been changed in substance, by God’s power, into his body and blood, ...
The doctrine of transubstantiation was made official.
Canon 2 addressed the "error of abbot Joachim." Joachim de Fiore (1135 - 1202), called by one modern scholar "The Man Who Invented the Future" (post) was the founder of a monastic order based on St. John, and he wrote on the apocalypse and the Book of Revelation. His theory was that the ages of the world mirror the Trinity, and that only in a future third age of the Holy Spirit would humankind truly understand Christianity and become spiritual. He submitted his works to Innocent in 1200, but died two years later before Innocent could reflect on them. Innocent since had decided the works were misguided. Joachim had contradicted Peter Lombard, calling Peter a heretic. Aquinas later condemned Joachim. Dante, on the other hand, placed Joachim in Paradise.
We therefore condemn and reprove that small book or treatise which abbot Joachim published against master Peter Lombard concerning the unity or essence of the Trinity, in which he calls Peter Lombard a heretic and a madman because he said in his Sentences, “For there is a certain supreme reality which is the Father and the Son and the holy Spirit, and it neither begets nor is begotten nor does it proceed”.
Joachim's idea of a progression through history and a lack of understanding of God until some future time did not suit Innocent. A French theologian, Amalric of Bena (see illustration), was likewise condemned in this Canon with a single sentence after about 1000 words against Joachim.
Canon 3 lasted what to do about heretics. Suspicion of heresy should lead to excommunication, If a year went by without the person recanting, then they would be called a heretic. Princes were to swear that anyone the Church deemed heretics would be banished from their lands. This Canon was shorter than the one on Joachim.
Tomorrow we will look at more.
