Did MLK Write the Church of the Brethren?

I am looking for something that I’m not sure exists.

I want to say that, years ago, I saw a Facebook post from the Church of the Brethren Historical and Library Archives that featured a letter that Dr. Martin Luther King, Jr. wrote to Brethren pastors. It may have actually been a telegram. King spoke of the Brethren’s reputation for peaceful resistance and social justice. On account of this mutual ethos, he requested that they’d show up at some event.

Maybe this is a figment of my imagination. “Archive fever” is real folks.

Fortunately for me, I know some specialists in Kingian and Brethren studies. If you have thoughts, please let me know.
