Quoting Blessed Titus Brandsma
from At the Fountain of Elijah
So the contemplative prayer of the Carmelite is also the strength of the active apostolate. The influence of the contemplative soul is not withheld from the apostolate. . . . So there is no opposition of the contemplative life to the active. The former is the great support of the latter. The mystical life is in the highest sense apostolic.
Titus believed in the seamlessness of the Christian life--prayer and work were parts of the whole. Whenever he was called from silence and solitude to help someone he would say that he was leaving God for God.
In the Lay Carmelite life, prayer should find its expression in service in the world. We go to prayer to meet God and in meeting God we are given our work to do. It is a fine balance--making time for prayer and for the service that springs from it, while actively serving our families and our Churches.
But the apostolate of the Lay Carmelite is not merely contemplative prayer, but showing how contemplative prayer "works-in" with an active life. We are blessed and nourished by our prayer and our example, when lived according to the Rule and in accordance with the disciplines of the whole Catholic Church, allows others to see the integration of the contemplative and active that may occur in every person. One of the primary messages of Carmel is that contemplative prayer is for everyone. The way of Carmel is a special call, a vocation; however, contemplative prayer is available to all outside of Carmel. A person who is part of no lay order is invited every bit as much as one who has joined. God wants intimacy with all of His children. Lay Carmelites demonstrate that it is possible to live an active life of service fueled by contemplation--Martha tempered by and informed by Mary. Perhaps it is not the highest or best calling--that is reserved for those whose entire vocation is contemplation. But we don't really want all the best gifts, but rather the gifts most suitable for us as God sees us.
Thus Blessed Titus shows us that leaving our prayer to help a friend, or leaving our prayer to feed the poor is leaving God for God. In this life of apostolic contemplation and service we can never really leave God.
