Today is the fiftieth anniversary of King's speech during the March on Washington. Martin Luther King, Jr. is commemorated on the Church's calendar on April 4 (or January 15 alternatively). The Collect for his remembrance is:
Almighty God, by the hand of Moses your servant you led your people out of slavery, and made them free at last: Grant that your Church, following the example of your prophet Martin Luther King, may resist oppression in the name of your love, and may secure for all your children the blessed liberty of the Gospel of Jesus Christ; who lives and reigns with you and the Holy Spirit, one God, now and for ever. Amen.
