Most, if not all, of these Justin Martyr quotes aligns with Latter-day Saint belief. (Iâd have to delve into the âunbegotten, unutterable Godâ phrasing a bit to give the 100% thumbs up.) Note that this passage says nothing about the Holy Spirit being co-equal, co-eternal with God, and also assumes that the Son is subordinate to the Father. So there are gaping Trinitarian holes in these quotes.
Note the non-Trinitarian subordinationism in this statement.
Regarding Justin Martyr, Edmund J. Fortman says the following:
On several occasions Justin coordinates the three persons, sometimes citing formulas derived from baptism and the eucharist, sometimes echoing official catechetical teaching. He worshipped the Father as Supreme in the universe; he worshipped the Logos or Son as divine but in the second place ; he worshipped the Holy Spirit in the third place. But he has no real doctrine of the Trinity , for he says nothing of the relations of the three to one another and to the Godhead . (Edmund J. Fortman, The Triune God: A Historical Study of the Doctrine of the Trinity (Philadelphia: Westminster Press, 1972), 47
Leo Donald Davis states âThough a step forward in Trinitarian thought, it is clear that Tertullianâs view is still somewhat immersed in the sensible. Spirit is for him really only attenuated matter, and imagination so pervaded his thinking that he could explain the unity of the divine substance in terms of an organic continuity and of accord within the human monarchy. His view as father and Son as of one quasi-material substance is different from the consubstantiality (homoousian) that will form the basis of Nicaeaâs pronouncements.â (Leo Donald Davis, SJ, The First Seven Ecumenical Councils, The Liturgical Press, pg 45)
âThere was a time,â he [Tertullian] said, âwhen there was no son to make God a Father.â (Leo Donald Davis, SJ, The First Seven Ecumenical Councils, The Liturgical Press, pg 45)
