Since the ... manage to get my thread closed that addressed John 6, and left this one open, the Judas Condundrum being relevant to this OP, I'll post it here
The biggest problem with Calvinist's interpretation of John six is not merely their fundamental misunderstanding of the word "draw". This can be debated back and forth with the Calvinist claiming "no man can come to me except the Father DRAW him", to which the Non Calvinist can reply, "Jesus said, If I be lifted up I will draw ALL MEN TO MYSELF".
The biggest problem Calvinists face on their interpretation is that of John 6 "all that the father giveth to me SHALL COME TO ME". The Calvinist have a fundamental misunderstanding of the phrase "all that the father GIVETH TO ME". If that portion is misunderstood, then it affects the proper interpretation of "SHALL COME to me", and the problem with the Calvinist interpretation here is....
JUDAS
To the Calvinist, only those CHOSEN can come to Christ. After all, that is the core of election is that the 'effectual' call only goes to those who are chosen. And, those whom are chosen being elect can not resist the effectual call. A Calvinist would not and can not admit, and still be a CONSISTENT Calvinist, that the effectual call goes to anyone who is NOT chosen, and can not be consistent by stating that being chosen is evidence by an effectual call.
Judas throws a major monkey wrench into the Calvinist interpretation of John 6.
Now in the following verses, pay close attention to the terms CHOSEN and GIVEN ("all that the father GIVES me").
"Jesus answered them, Have not I chosen you twelve, and one of you is a devil?" John 6:70
"And now I am no more in the world, but these are in the world, and I come to thee. Holy Father, keep through thine own name those whom thou hast given me, that they may be one, as we are. While I was with them in the world, I kept them in thy name: those that thou gavest me I have kept, and none of them is lost, but the son of perdition; that the scripture might be fulfilled."
John 17:11-12
Now the Calvinist may latch on to "that the Scripture might be fulfilled" which presents another monkey wrench to Calvinist theology. How does God predetermine someone CHOSEN whom the Father GAVE to Christ to be damned?
Judas was clearly CHOSEN, and clearly one of whom Christ Himself said that the Father GAVE TO HIM. YET HE WAS LOST AFTER HE WAS GIVEN TO CHRIST, and AFTER HE WAS CHOSEN.
Now this presents not only a problem with the Calvinist view of "draw" and "given" and "chosen" but it also presents a problem with the view of perseverence of the saints and eternal security-UNLESS the Calvinist interpretation of John 6 is wrong!
The fundamental difference in understanding the Judas conundrum is to properly understand John 6:37 in it's ENTIRETY. Whom does the Father GIVE to Christ? Is it merely those who are CHOSEN according to the Calvinist view of election? No. Prior to salvation being offered to the Gentiles, the Father GAVE all of Israel to Christ, but that isn't the only catch. The ones that "SHALL COME" to Christ are the ones of whom have chosen to come to Christ. Notice the rest of John 6:37 "and he that cometh unto me".
JUDAS NEVER CAME TO CHRIST. In order for John 6:37 to be consistently applied to the believer, it is not merely the Father giving believers to Christ, it is also them COMING TO HIM. Judas never came to the Lord, he always referred to Christ as "master" and not Lord, and actively sought to betray him, yet he was GIVEN to Christ and CHOSEN.
The Calvinist can not reconcile the Judas conundrum by maintaining their view of John 6:37, and be consistent with their view of perseverance of the saints AT THE SAME TIME. The problem is as follows:
1. The Father gives all of the elect/chosen to Christ
2. Those that are given to Christ SHALL COME
3. Only those who are elect and chosen can receive the effectual call and those who receive the effectual call can not resist God's grace that leads to salvation.
4. Judas was given to Christ as well as chosen
5. Judas was lost
6. Therefore a person given to Christ and chosen can lose their salvation.
The Calvinist to be consistent with all five points of their TULIP theology would reject the conclusion as would anyone who, like myself, also believes in eternal security. Therefore one of the premises MUST BE WRONG in order to consistently maintain perseverance of the saints and eternal security. Based on John 6:70 and John 17:11-12, the Calvinist can not reject 4 and 5, but the Calvinist MUST reject 6 to be a consistent Calvinist. The only options are that the Calvinist view election, irresistible grace, and the effectual call must be rejected.
