In Book 3, Chapter 38 of The Imitation of Christ, Christ says, “You must diligently make it your aim, that in every place and in every action or outward employment, you be inwardly free and master of yourself, and that all things be under you and not you under them, that you may be the Lord and ruler of your actions and not a slave or bondsman, but rather a free man.”
Fr. Robert Nixon comments, “This is a great call to freedom of soul. Freedom is something which perhaps we tend to think of in political terms as something associated with liberalism and so forth. But in fact, freedom of soul, true freedom, is one of the foundational values of Christianity.”
