The Big TentBilly Graham was a well-known evangelist of the 20th century, who became famous not only for the content of his sermons, but also because of his close relationships with notorious politicians and Famous leaders of that era helped him become the symbol of evangelism by "making evangelicalism the dominant American faith" (The Big Tent 31). Graham's religious beliefs evolved from the fundamentalism in which he was raised to an open and liberal conception of faith, resulting in what is called the New Evangelical Approach to Religion, a more moderate and tolerant way of interpreting the message of God. As he described himself, he was “a theological conservative but a social liberal” (The Big Tent 28). Much like Graham, throughout the 20th century the religious beliefs of the people moved from one extreme to the other, passing through a more moderate expression of these beliefs, accompanying the social and political events taking place at the same time. Around 1900, general religious belief was based on certain principles considered the foundation of true faith: the Bible is the only truth, the divinity of Jesus Christ born of the Virgin, the bodily resurrection of Christ and the existence of biblical miracles . At the same time, Darwin's theory of evolution initiated a different approach to religion that placed greater emphasis on the humanity of Christ and questioned the divine quality of creation. Although in 1918 there were other religious tendencies (such as Baptists, Methodists and Presbyterians) which differed among themselves and all shared a common orthodoxy, Darwin's theory changed this scenario by paving the way for a new expression religious beliefs: modernism, which favors the concept that God can be seen in the evolution of man on earth. As a result, some Presbyterians and Baptists began practicing practices based on the new liberal approach to Christian orthodoxy, while their opponents (now called fundamentalists) claimed that liberal theology was a false religion that could not exist in parallel with what they called true religion. faith (as theologian J. Gresham Machen argued). Soon these arguments led to a modernist controversy outpacing the success of Christian missions, and by 1940 fundamentalism was no longer as popular as before. The fundamentalists began to divide even within their own group, giving rise to what were called the Separatists, who were the most radical believers..
