TOVs provide a service to the Church by supplying a practical method for learning to pray in an orderly, varied and gradual manner, from the first steps to the depths of contemplation. The members are introduced to the prayer life, and helped to combine  prayer with engagement in ordinary temporal activities; to revive their awareness of their status and dignity as baptized Christians, and their responsibilities towards the mission of the Church in the world; to become hothouses of lay vocations to the apostolate and service of the Church in the dioceses and parishes.
