Reflecting on vocations again, St. Albert writes this in the Rule he proposed for "B. and the other hermits under obedience to him, who live near the spring on Mount Carmel."
Rule of St. Albert
Many and varied are the ways in which our saintly forefathers laid down how everyone, whatever his station or the kind of religious observance he has chosen, should live a life of allegiance to Jesus Christ--how, pure in heart and stout in conscience, he must be unswerving in the service of his Master.
"In allegiance to Jesus Christ" is the Carmelite motto. But it is uniquely Carmelite. Every Christian must live a life in allegiance to Jesus Christ, or risk being overwhelmed by the world. How one finds the proper bonds of allegiance and what outward manifestation that might have will vary. But it is not only the Carmelites who must live in allegiance with Jesus Christ, but everyone.
Also, it would be well to consider the origin of the term allegiance before it is dismissed as too light a bond.
