Snow, the only thing “novel” about the Trinity is its name. The Bible doesn’t mention the word “Trinity” anywhere. But it can be seen throughout the Gospels. I don’t feel like looking them all up right now, but Mt 28:19 comes to mind.
Then my request of you is the same as my request of Paul.
Please cite the specific Biblical verses that demonstrate that the three persons of God are of the same ontological substance.
People say that the Trinity doctrine - the whole thing - is in the Bible but so far I have never found a single person who can name the specific verses that prove consubstantiality.
A Jesuit [Catholic] scholar says this:
“There is no formal doctrine of the Trinity in the New Testament writers, if this means an explicit teaching that in one God there are three co-equal divine persons. But the three are there, Father, Son, and Holy Spirit, and a triadic ground plan is there, and triadic formulas are there…The Biblical witness to God, as we have seen, did not contain any formal or formulated doctrine of the Trinity, any explicit teaching that in one God there are three co-equal divine persons.” Edmund J. Fortman, The Triune God: A Historical Study of the Doctrine of the Trinity (Philadelphia: Westminster Press, 1972), 32,35
“…there is no trinitarian doctrine in the Synoptics or Acts…nowhere do we find any trinitarian doctrine [in the New Testament] of three distinct subjects of divine life and activity in the same God head…These passages * give no doctrine of the Trinity, but they show that Paul linked together Father, Son, and Holy Spirit. They give no trinitarian formula…but they offer material for the later development of trinitarian doctrine…[Paul] has no formal Trinitarian doctrine and no clear-cut realization of a Trinitarian problem…in John there is no trinitarian formula.” Edmund J. Fortman, The Triune God: A Historical Study of the Doctrine of the Trinity (Philadelphia: Westminster Press, 1972), 14,16, 22-23,
“The God whom we experience as triune is, in fact, triune. But we cannot read back into the New Testament, much less the Old Testament, the more sophisticated trinitarian theology and doctrine which slowly and often unevenly developed over the course of some fifteen centuries.” Richard P. McBrian, Catholicism (Minneapolis: Winston Press, 1980), 347
“This double series of texts manifests Paul’s lack of clarity in his conception of the relation of the Spirit to the Son. Paul shares with the Old Testament a more fluid notion of personality than the later theological refinements of nature, substance, and person. His lack of clarity should be respected for what it is and be regarded only as the starting point of the later development.” J Fitzmyer, Pauline Theology: A Brief Sketch (Englewood Cliffs, New Jersey): Prentice-Hall, 1967), 42.*
