Martin Luther King, Jr. – Letter from a Birmingham Jail

Dated April 16, 1963, Martin Luther King wrote a letter from jail in Birmingham during the non-violent campaign there. In the letter, he defended the strategy of non-violence used in the Birmingham campaign.
One of the striking elements of the letter is King’s disappointment with the white clergy in the South. Here is a key passage:

Currently, white and black evangelicals are divided in obvious ways as we observe another MLK, Jr Day. For instance, African American Baptist churches are leaving the Southern Baptist Convention as white leaders there take aim at Critical Race Theory while yawning at Christian nationalism. White evangelicals as a group find themselves in much the same place as when King, Jr. wrote in 1963. I long for a change. I long for an end to concern for ideological purity and a striving for relational purity.
