From “The Return to the Bible” by D. Martyn Lloyd-Jones:
From the moment that philosophy was given the place of revelation in our studies and in our pulpits, things really began to go wrong. Of course, for a time, people continued to attend church and chapel in fairly large numbers, partly out of mere habit and custom, without realizing exactly what was happening, but we can be perfectly certain that the Church lost her authority and power from the moment that she ceased to believe firmly in the authority of the Word of God, and when she became doubtful and hesitant in her presentation of its doctrines to the people.
From the moment that the idea began to gain currency that the Bible was the history of the quest of mankind for God, rather than God’s revelation of Himself and the only way of salvation to mankind, the Church began to decline and to wane in her influence and in her power. From the time the Church threw overboard the great evangelical doctrines, and substituted for them a belief in the moral and spiritual evolution of mankind, and began to preach a social gospel rather than a personal salvation — from that moment church attendance really became a mere matter of form, or a merely pleasant way of gratifying one’s appetite for ceremony, ritual, oratory, and music.
