The Trinity is the central mystery of the Christian faith. The term describes the inner life of God, who is an eternal communion of Persons and a Family whose life is love. Is the concept of the Trinity a Christian invention, derived from Greco-Roman pagan ideas? Or do we already find hints of the Trinity in the Hebrew Bible and in Jewish sources?
The Trinity is a distinctively Christian idea, but it articulates the concept of G-d implicit in the Jewish as well as the Catholic experience of G-d, for Jews, like Catholics, know G-d as Father (Source), as Son (Shekhinah), and as the Holy Spirit (His Love).
