Oh, I don't in the least worry about it shaking my faith.
But, if I resent the depiction of the life of Jesus as presented as a lie by the Bible, if I am offended by the treatment of Jesus, I reserve the right to speak up about it.
I also reserve the right to know that the ignorant in our society will latch on to any doubt about religion thrown at them and many will be given a new reason not to believe in the Church and any teaching of Jesus. So, this is just a tool that is going to be used against them and their acceptance of Jesus, and therefore their eternal life.
Just because you don't consider it of worth as an issue, does not mean I have to feel the same way.
It is about time that I stood up for Jesus when His life is attacked as I have not been known for contributing much help. But, this is offensive as is any other effort by entertainers to mock His gift to man (ex. Madonna and the cross in her newest episode of shock).
What did Madonna do now?
