Manichaeism

As other people have said before, this is also my first time to write in a blog, I did not know how to get into a blog not even what to write on it. But everyday you learn new things right?
What was interesting for me about reading “The Confessions” was that I started to question myself hundreds of questions while I was advancing in the reading. One of these questions was about the “good” and the “evil”. Therefore I decided to look more about the Manicheans, and why did Saint Augustine really reject their ideas.
So this is what I found:
For Manicheans, there are two eternal roots, Ahriman is the god of the Old Testament, the god of darkness, and Hormuz is the god of the New Testament, the god of the Light. We as humans are made of these two roots, our body will be the perverse side, while our souls are some piece of divinity that is suffering because of its incarceration in the body and its carnal desires. (This part will relate us to Plato’s ideas)
At first the two substances were separated. However, there was a disaster and both roots mixed, and since that day, they have been in a perpetual struggle, which symbolizes the history of human progress.
Saint Augustine studied Manichaeism for a while because he was trying to understand the origin of the evil. However, he rejected this theory because the evil should not be seen as a substance, instead, as the lack of good, as Plotino explained. By that way, he discovered that God never created the evil, but it just existed when the good was not present. To resume, the evil resides in the counter position of what is sensible to God.
