It was never the real Jesus, it was Jim Caviezel the whole time. Gibson did base his movie on scripture...and he quoted scripture a great deal. Some details were based on mystic visions of a catholic nun. Do I think these visions are (pardon the pun) "gospel?" No, but nothing in the movie was against scripture.
I know nothing of this, but I will say that Jim Caviezel's portrayal of Christ has played a role in many people coming to Christ. Regardless of the situation behind the movie, God has used this movie to His glory....He's good about doing that with our feeble efforts, sometimes.
Mel Gibson and his cast and crew produced a fine piece of cinematography. It is an affecting portrayal of the crucifixion which focuses on the suffering of Christ. That's it. Anything else that might be attributed to this movie: reaching the lost, for example, is the work of the Holy Spirit, not Mel Gibson.
If we were to review every instance where the Holy Spirit worked in our lives to convict us, from that first time being convicted of our sin forward, and looked for fault in the humans involved, we would be in sorry shape.
I know at our church, a sinful pastor preaches every sunday and pleads for the lost to come to Christ. I hope the focus is on Christ. I know that anyone resonding and coming to Him, are a result of Christ...and not the sinful preacher.
I am curious, though, about your current situation. XD, in another post, you were worried about a bible version, citing a ten year old reference. Now, you are concerned about something that happened a few years ago...Good information is always good, but where is this all coming from?
