Sometime ago, it became rather fashionable to identify oneself as a "red-letter" Christian. The implication was that the words of Jesus should give us the clearest direction when it comes to being his disciple. (Often times the designation was used as a foil against those who mindlessly follow Paul's instructions, ["I am of Christ, You are of Paul,"] as if Paul and Jesus were not on the same page--which is another topic altogether.)
To be sure, Jesus said some amazingly challenging, provocative, and transformational things (the parables!). But, merely parroting what he said (we eventually discover) seems to do more harm than good. We can argue over the Sermon on the Mount (did he really teach that we shouldn't defend ourselves?), quoting the "red-letter words" back to one another like weapons, as if the war of words will settle the matter. Fighting over "what Jesus really meant" seems to be our holy occupation, especially in the blogsphere.
But, the more I think about it, the more I want to become a "black-letter" Christian, known by what I do more than what I say. Indeed, the way Mark saw it, the black letters (works of Jesus) were more important to his gospel story. And, I hope the "black letters" of my life are more important to the gospel story too.
In other words, pay no attention to these words.
