25 The history of the Church is like a mirror, which reflects the life of the Church through the ages. It proves, better far than civil and profane history, the sovereign liberty of God and His providential action on the march of events. They who study it must never lose sight of the fact that it contains a body of dogmatic facts which none may call in question. That ruling, supernatural idea which presides over the destinies of the Church is at the same time the torch whose light illumines her history. Still, inasmuch as the Church, which continues among men the life of the Word Incarnate, is composed of a divine and human element, this latter must be expounded by teachers and studied by disciples with great probity. "God has no need of our lies," as we are told in the Book of Job.(16)
