The 'Economy of Salvation' (oikonomia) refers to the works by which God reveals Himself and communicates His life to humanity (CCC 236). It is distinguished from 'Theology' (theologia), which refers to the mystery of the internal life of the Trinity (CCC 236).
The Sacramental Economy
The Church speaks of the 'Sacramental Economy,' which is the communication of the fruits of Christ's Paschal mystery through the liturgy (CCC 1076). Through this economy, Christ remains active in His Church (CCC 1076, 1091).
Frequently Asked Questions
How do Theology and Economy relate? God's works (Economy) reveal who He is in Himself (Theology), and His being enlightens our understanding of His works (CCC 236).
May the Lord bless you and keep you.
