I've always liked this photo as it reminds us that King was a man of the people, as was the Lord whom he followed.
However, the Episcopal Church remembers him not in January, which is the government holiday, but on April 4th, which was the day of his assassination. It is ancient tradition that martyrs be remembered on the date of their martyrdom.
In anticipation of his feast day, and in recognition of the federal holiday [when the government honors a highly educated American by closing all public schools], the Episcopal Church readings for Martin Luther King, Jr.'s day may be found here.
And since the media occasionally forget that he was a practicing Christian and person of faith, we remember him by his title "The Rev. Dr.".
