The Divine Economy reveals the unique role of the Father, Son, and Holy Spirit in bringing about God's plan for the world, while also operating as one and the same operation. It showcases the beauty and simplicity yet mystery of God’s work in the world.
The divine economy reveals both the specific characteristics of each divine person and their shared divine nature. The mission of the Son's incarnation and the gift of the Holy Spirit demonstrate these properties within the divine economy.
In paragraph 258 of the Catechism, the unique yet unified role of the Father, Son, and Holy Spirit in the divine economy is explained, and how they bring their life to us in the world. The prayer of Blessed Elizabeth of the Trinity is also mentioned as a beautiful example of devotion to the Holy Trinity.
