Can. 603 §1. In addition to institutes of consecrated life, the Church recognizes the eremitic or anchoritic life by which the Christian faithful devote their life to the praise of God and the salvation of the world through a stricter withdrawal from the world, the silence of solitude, and assiduous prayer and penance.
§2. A hermit is recognized by law as one dedicated to God in consecrated life if he or she publicly professes in the hands of the diocesan bishop the three evangelical counsels, confirmed by vow or other sacred bond, and observes a proper program of living under his direction.
One of my favorite things about the Franciscan life is that it is expressed in every state of life: secular and religious, lay and cleric, and every shade and combination among them.
