Concerning MLK, a thought occurred to me. I had always been somewhat ambivalent about the holiday controversy. Recalling all the arguments about whether or not he should be honored with a national and/or state holiday (this blew up in AZ over a decade ago), all the positives and negatives - and there were definite negatives (adultery) - how do you categorize the man?
The daily readings in the Church now come from the kingdom books and involve King David. A man after God's heart. A man who also committed an adulterous rape then murder.
"I would sin like David, if only I could repent like David"
I categorize MLK as more positive than negative. He was also a plagiarist and (some say) a communist fellow-traveler.
OTOH, he was a non-violent guy, evidently learned in Scripture and understanding of Right Order.
All in all, a human being.
