Graham (1918-present) was raised in a branch of the Presbyterian Christian Church, and was anti-evangelistic in his early years, but after attending an evangelist revival meeting led by Mordecai Ham, he became a believer in the Gospel, and later, America's most famous Evangelist. He stressed a personal, positive relationship with God, or more specifically, with Jesus, using the Bible as his only authority. He said that he wanted to transcend all class and ethnic divisions. This universal message, delivered with Graham's charismatic preaching power, made him one of the most admired men of the 20th century. His great influence extended to all the Presidents of his time.
