The distinction I'm making is between "the devil entered into Judas" and "the devil was placed in him".
It's our choice which.
I totally agree. This would seem to be contrary to the Calvinist position, though.
On the contrary. Calvinists would say that Judas was foreknown and predestined to betray our Lord Jesus.
It is more contrary to a "free will" belief which would say Judas had a choice, he just made the wrong one.
Please remember Jesus himself said that have I not chosen you and yet one of you are a devil. If Judas hadn't already made the choice I wonder how Jesus knew which choice Judas would make?
