Read canonically, the New Testament gives us reason to affirm that God is solely revealed in Christ, who with the Holy Spirit, share God’s exclusive right of receiving worship. Whereas some Second Temple texts blur the line between a wide range of heavenly mediators and God, the canonical account is that there are no others who can be identified with God in this way. Though some Second Temple texts show reverence, on rare occasions nearing cultic worship, to heavenly mediators, the entirety of the New Testament liturgical practice is marked by trinitarian forms suggesting that proper worship involves Father, Son, and Spirit. Because Christ, the mediator of God, is identified with him in worship, we have laid an exegetical foundation for the doctrine of consubstantiality. Whereas angels are mediators who reveal a God that is other, meaning that they cannot rightly accept worship, the New Testament account drives us toward what modern systematicians have called God’s self-revelation and self-communication. In some sense, that is the entire dogmatic purpose of consubstantiality: demonstrating that when Jesus reveals the Father, he is also revealing his own nature.
