Ontological equality relates to equality with respect to being. Joe and Frank are ontologically equal in that they are both human. In this sense, The Father and the Son are ontologically equal in that they are both God. Economic equality relates the roles one takes in the world. Joe is the head of Frank because Joe is Frank's boss. In this sense, the Father and the Son are not economically equal because the Father is the head of Christ.
I am aware that TRINITARIANS believe ever since the second Person of the Trinity assumed a human body that the second Person of the Trinity is NOT economically equal to the first Person of the Trinity.
But my questions concern BEFORE the second Person of the Trinity assumed a human body...
1) Was the second Person of the Trinity economically equal to the first Person of the Trinity BEFORE he assumed a human nature?
2) Was the second Person of the Trinity economically equal to the first Person of the Trinity BEFORE the foundation of the world?
I think TRINITARIANS will say No and No, but I would like confirmation.
Are you able to provide an overview of what you believe? Here is mine...
For this creation, YHWH God (the only one who transcends all creations) determined to create a universe with a kingdom of redeemed humans (living souls) for his glory where he would reign as a living soul himself. The Scriptures describe how God would accomplish his plan. In an instant, transcendent God (called God the Father) created the supernatural and space-time of this universe and also became immanent as a spirit (called the Spirit of God) and in the form of a living soul (called the Word of God) with a glorious body. God the Father then created all things within the universe by the power of the Spirit of God commanded by the Word of God. But whereas God created a human spirit and soul for each of us, God himself as the Word became the human spirit and soul of Jesus. At his conception, Jesus' glorious body was changed to a mortal body to be made like us so he could make reconciliation for our sins. At his resurrection, Jesus' mortal body was changed back to a glorious body and he will also give each of his elect a glorious body when he returns to reign in his kingdom forever.
