We honor King when we try to apply his example to our times. William F. Buckley on Martin Luther King:
We read the speeches of Martin Luther King, Jr., whose life we celebrate while tending to ignore the essence of his beliefs, acclaimed by him (as by Abraham Lincoln) as the ground of his idealism. A bizarre paradox in the new secular order is the celebration of Dr. King's birthday as a national holiday acclaimed as the heartbeat of articulated idealism in race relations, conscientiously observed in our schools [think of all the colleges and public schools that ignore national holidays such as Veterans Day--but recognize the King holiday] with, however, scant thought given to Dr. King's own faith. What is largely overlooked, in the matter of Dr. King, is his Christian training and explicitly Christian commitment. Every student is familiar with the incantation, "I have a dream." Not many are familiar with the peroration. The closing words were "... and the glory of the Lord shall be revealed, and all flesh shall see it together." [speech honoring the Heritage Foundation, Oct. 20, 1999, p. 472]
The speech, from collected Buckley speeches, is available via google books.
Teaming with secular media, the Obama Administration is clearly hostile toward organized religion, in particular the Catholic Church. Would King have stood for the churches or the Obama program? Would he have joined the March for Life?
Update: The Buckley speech can also be found here, with some added commentary, as Michelle notes in the comments below. Please read Lucas Morel's comment as well--an excerpt from his MLK Day remarks.
