Francis Schaeffer

One of the most influential Christians of recent times, Francis Schaeffer pioneered modern apologetics. Converted from agnosticism, Schaeffer went on to study at Westminster Theological Seminary under Cornelius Van Til. Throughout his life Schaeffer countered the philosophy of relativism by defending the existence of absolute truth. In his biography Colin Duriez describes Schaeffer's teaching as being able to "deeply and personally influence people of every age and position… in a way that few others have."
