It is interesting if one examines Billy Graham's history of serving the Lord. His victorious battles for the Lord as well as his failure...
I wish to study this further...into the Question category:
What would make Billy Graham draw a grey line on the doctrine of christology and soteriology? Someone who has, in his earlier years, proclaimed the Gospel so fervently. What Kairos may have sparked this change in his testimony?
Perhaps his friendship with Carl Barth caused him too into Barth's theology.
