Why does the Judeo-Christian God have such a bad temper?
Me and God frown whenever you tempt us to laugh!
Stuck in their assumption that if the Bible is literal, inerrant, absolute, unchanging and possessed of only one true interpretation, those who lead believing Christian soldiers onward cannot maintain troop discipline if humor is allowed to flourish.
Get your search engine to look for Christianity, God, humor, soberness, solemnity, etc. and you will find (I promise you) serious and earnest sermons and essays on the evil of laughter.
They may appear extreme and apologists may try to dismiss them as such, but you will find writings and sermons openly critical and condemning of popular Christian writers, speakers and pastors who use and even worse – praise – humor as part of a “godly attribute.”
This sort of thinking represents one powerful aspect of why it has been said that Christian humor is an oxymoron.
