You may read the Desert Fathers, the Cappadocian Fathers and St. Gregory Palams too. It may shed some light on your conviction.
But to respond to your last sentence -- do you think Judas thought that Satan was his guide?
Hiding behind this catch-all Trump card "I believe the Holy Spirit is guiding me" is something that is not only freely absued, but something that has been shown to be historically and theologically invalid on numerous occasions.
kosta-"...do you think Judas thought that Satan was his guide?
Each person is to examine themselves to see if they are in the faith. You can only do this by researching this information out; not by relying upon what someone tells you. Judas wasn't interested in the message of Christ. The little that we do know about Judas from scriptures is that he was a thief who stoled out of the general funds. This wasn't the message our Lord Jesus was preaching. Had he examined himself, he would have reached that conclusion except we know that Judas was preordained for the purpose of betraying our Lord.
A converse question to yours: Do you think our Lord Jesus prayed that Satan wouldn't get a hold of Judas in the same way He prayed Satan wouldn't get a hold of Peter?
