Schaeffer's life is one of compassion and orthodoxy- often a rare combination. He was lovingly determined to fight for a theologically pure church. He took a stand against modernism and Unitarianism, without neglecting to love people, serve his congregation, and have an exemplary marriage to Edith Schaeffer.
Schaeffer is better known for being a great apologist. After feeling God's call he started a work in Switzerland named L'Abri. L'Abri (french for shelter) was designed to be a non-judgemental environment for people to visit and explore questions about God and life. The centre still runs today to carry on the work and legacy of Francis and Edith for Jesus glory!
