The Mason Temple Church of God in Christ is is the international sanctuary and central headquarters of the Church of God in Christ. It was first built in 1941 in order to replace the main "Tabernacle" for the COGIC Holy Convocations that burned down in the late 1930s. After its completion, it was named after the founder of the COGIC, Bishop Charles Harrison Mason. Not too long after its dedication, the street it was on, formerly known as 5th Street, was renamed East Mason Street, in honor of Bishop Mason. In 1961, Bishop Mason was emtombed in a marble crypt in the basement of the church. On April 3, 1968, Martin Luther King, Jr. delivered his final speech "I've Been to the Mountaintop" in the sanctuary of Mason Temple. Bishop C.H. Mason was the first and only pastor of the church from 1941 to 1961. After his demise, Bishop O. T. Jones, Sr. made a proclamation saying, "No member of the clergy or any minister shall assume the position of Pastor of the Mason Temple Church of God in Christ...for the church shall serve as a "museum" of Church of God in Christ history."
