As ruler of everything, God has a plan of salvation. This idea of a plan of salvation is especially developed by Ignatius. In his letter to the Ephesians, he speaks of the “economy towards the new man.” This is a. wonderful summary of the Christian message: economy towards the new man. Economy means “building a house.” But this word is used in our culture for what we call economic production. It is used in the Greek period for the structure of God and world, in their relationships. There is an economy of the Trinitarian thinking: Father, Son, and Spirit. They only together are God. There is an economy of salvation, the building of the different periods which finally led to the new man. This idea of the new man, or new creature, or new being, as the aim of the history of salvation, is an important contribution of these theologians.
