1997 interview with Robert Schuller on the Hour Of Power tv ministry. Maybe I'm mistaken about the same views he had in the 60s, but I could have swore I saw that somewhere. Here's the transcript, pasted from somewhere else.
Schuller: Tell me. What do you think is the future of Christianity?
Graham: Well, Christianity and being a true believer, you know I think there is the body of Christ, which comes from all the Christian groups around the world, or outside the Christian groups, I think everybody that loves Christ or knows Christ whether they are conscious of it or not they are members of the body of Christ. And I don´t think that we are going to see a great sweeping revival that is going to turn the world to Christ at anytime. I think the apostle James answered that in the first council of Jerusalem when he said that God´s purpose of this age is to call out a people for His name. And that´s what God is doing today; He´s calling the world for His name. Whether they come from the Muslim world or the Buddhist world, or the Christian world, the non-believing world, they are members of the body of Christ because they have been called by God. They may not even know the name of Jesus, but they know in their heart that they need something that they don´t have, and they turn to the only light that they have, and I believe that they are saved, and that they are going to be with us in Heaven.
Schuller: What I hear you saying is that it´s possible for Jesus Christ to come into a human heart and soul and life, even if they´ve been born in darkness and have never had an exposure to the Bible. Is that a correct interpretation of what your saying?
Graham: Yes it is. Because I believe that. I´ve met people in various parts of the world, in Tribal situations, that they have never seen a Bible, or never heard a Bible, and never heard of Jesus, but they believed in their heart that there was a God and they tried to live a life that was quite apart from the surrounding community in which they lived"¦
Schuller: (interrupting) Fantastic! I´m so glad to hear you say that. There is a wideness in God´s mercy.
Graham: There is. There definetly is.
