In all humility I must say that God has not inspired me to feel good about the Church's practices regarding Negroes.... when my wife and I went to San Francisco Ward's bishop to renew our temple recommends, he told us that anyone who could not accept the Church's stand on Negroes as a divine doctrine was not supporting the General Authorities and could not go to the temple. Later, in an interview with the stake president we were told the same thing: if you express doubts about the divinity of this 'doctrine' you cannot go to the temple.
