Daniel José Camacho writes:
Cone’s statement that “God is black” has always been grounded in Jesus’ Jewishness and the biblical narrative which presents God as being in solidarity with the oppressed. As he has clarified on numerous occasions, it is a symbolic statement and not a statement of biology or literal skin color. At the same time Christianity has said “God is white”—in deeds if not in exact words—for the past 500 years. That some hear God’s blackness as a zero-sum statement is a mistake.
In an interview this past January, Cone told HuffPo’s Paul Rauschenbush:
“God is red. God is brown. God is yellow. God is gay…I don’t use blackness as a way to exclude anyone.”
