Today I heard an instructor (a monk) saying:
At The Third Council of Constantinople, counted as the Sixth Ecumenical Council by the Orthodox Church, the Catholic Church and other Christian groups, met in 680/681 and condemned monoenergism and monothelitism as heretical and defined Jesus Christ as having two energies and two wills (divine and human).
And he explained that Jesus had two wills, as a human, he was able to do the wrong or the right thing, he chose the right path, to show us that we could be just like him and follow the road to salvation. He also had the will of a God, because he is God.
He added, we all have two wills, take saints as an example, they have the will of a human, they can make decisions, to do the wrong or the right thing, but when they become saints, they have the will of a saint, which is to be with God and so on.
So I asked him: well the devil was a spirit right? So he made the wrong decision and became a devil, in fact all devils were angels. Which poses two questions.
If Spirits/souls/angels (call them what you want) do think and make decisions, wouldn't be possible to someone in heaven, maybe a saint, to make a wrong decision and end up in hell, just like the devil?
If they don't think and don't make decisions, meaning that if you were a saint on earth, you'll be a saint forever. Then how did the devil make the wrong decision? Furthermore, how do spirits live in heaven or hell, as objects?
He said we'll discuss that later, let me finish the course, so I'm bringing this topic to here.
