The Devotionary is the official prayer book composed by Blessed Justino Russolillo to regulate the life of community prayer of the religious of the Society of Divine Vocations. And it is also used among various members of the Vocationalist Family throughout the world, especially for those who want to work for their own sanctification and for all souls. In the Devotional, there is a whole spirituality for the Ascension of the soul (person) to the Divine Union.
