The purpose of the Order consists in seeking and worshiping God, as well as working in the service of the people of God: together with one heart, and in fraternity and in spiritual friendship. As the rule admonishes us: the main purpose for our having come together is to live harmoniously in the house "intent upon God in oneness of mind and heart".

Nuns by reason of the sanctity of their calling aim to be for the Christian people and for the world "a source of heavenly grace" by the testimony of their lives, their prayers and all other forms of service proper to contemplative Augustinian life.St. Augustine writes: "If you love God, win all others to his love. Win as many as you can, exhorting, bearing up with them, praying, discussing, giving reasons, but gently, calmly: win them for love".
