Wow. Great comments on that last post. I was glad that you caught the problems with the Francis Bacon quote (and Bacon himself). If you haven't read the comments, check them out and get going with your artistic, argumentative-self.
Here's another question/thought - do artists have more of a responsibility than others to make their work "Christian"? This leads to the question, What exactly is Christian art? Do we ever talk about Christian plumbing? Or Christian carpentry? Maybe we should...but what makes something "Christian" as opposed to...well, as opposed to what? I don't buy into the secular/sacred distinction because nothing lawful is beyond Christ's reign or beyond the possibility of glorifying God. This is partly why I like Steve Turner's idea so much: let's be Christians, men and women who love Christ, are passionate about righteousness and holiness and Bible reading and worship and all that good stuff. Then, let's be artists, or doctors, or mothers, or whatever is lawful and good. Tacking on a Christian veneer to art - say, putting Bible verses on all our pictures - makes art as much "Christian" as putting a fish emblem on your car makes your driving Christian.
On the other hand, it still seems that artists (and pastors, I think) have much more opportunity to lead people into sin than, say, plumbers do. A plumber may do some plumbing with a bad attitude, or without believing in the Kingship of Christ, but that doesn't make me stumble in sin. But if an artist uses all the tools at his/her disposal to either convince me of something that isn't true or lead me into sin, does that artist share some culpability for that? So, while the possibility of glorifying Christ exists in all professions, I believe we ought to be honest and tell the artists among us that they bear a special responsibility in Christ's Kingdom.
Always more questions, but these things are so important for us to talk about and wrestle with.
Last year our youth came back pretty from the high school winter conference pretty jazzed about Pastor York's lectures, which were themed on the life of Athanasius. Several reported on this "list" of how to decide what to do and what not to do. Please read it and think about it. It bears greatly on this topic of our involvement with the arts.
