There seems to be a fair bit of theological humor circulating today. David Opderbeck shared a link to The Semi-Pelagian Narrower Catechism. To find it funny, you have to be familiar with both a certain brand of American conservative Evangelicalism and also with one ore more classic catechisms.
I also had pointed out to me this article on “Coffee as a Means of Grace.” Coffee is, of course, no laughing matter, but the article is admittedly amusing.
