I like you're writing and your blog, and am especially interested in what you say about art being persueasive.
Does this mean that art is evangelism?
I don't know how long ago you made this comment on my blog but I just recently saw it. If it was awhile ago, sorry for the slow response.
Art is a form of communication, although not necessarily in a conceptual way. Art can be used in evangelism but not all art is evangelism.
Art can say things that words and concept can't. Science has reduced reality to concepts of thought that fits in our heads. Anything that does not fit, does not exist. Because art points to a reality that is beyond concepts of thought, I believe that art is essential to reconnected people to Christ and his Church.
