Of course the case of the Christian Church planted among the nations must differ, in various ways, from that of any sect forming in connection with religious awakening in a territory of professing Christianity.
The failure of Christianity in the areas west from Sicily was even greater, and was increased by the spread of Arab outlooks and influence to that area, and especially to Spain.
So I see that Christianity in believing in a Creator pulls together more facts, data, inner experience and ability than any mechanistic view could hold for me.
Christianity stands or falls as a living program, a way of life, made concrete in the life of man by the life of God through the life of the concretely living Christ.
