I'm not judging Protestants who sought to escape tyranny, just in terms of doctrine their weird acceptance of some Catholic doctrine and tradition certainly suffers on this subject. "Theosis" is just a label for the doctrine, just like other labels used like
[Edit: I just now read the rules that bans discussing the Trinity, excuse me]. Coined from ancient patristic statements like;
- "God... became what we are in order to make us what he is", St Irenaeus of Lyons (130 A.D. Grant, Irenaeus of Lyons 1997, 164)
- "God became man, so that we might be made gods", St Athanasius of Alexandria (295 A.D. On the Incarnation of the Word 54)
What is called theosis / divinization / deification: i.e., is what the Bible describes as the partaking of and sharing in divine nature of the Lord as St. Peter once wrote (2 Pet. 1:4) by invitation, by adoption, by gift. Human persons are called to be transformed and transfigured (meta-morphed) from a fallen nature and "changed into the same image from glory to glory" into the same glory as the Lord (2 Corinthians 3:18). John taught “we are the sons of God, and it doth not yet appear what we shall be: but we know that, when he shall appear, we shall be like him; for we shall see him as he is.” (1 John 3:2). Tell me how this is not theosis, that we can become like God?
Indeed, the "Scripture cannot be broken" as you quote Jesus saying, when he used Psalm 82:6 in John 10:34
1. Jesus’ prefaced his quotation by asserting that he and the Father were one (10:30).
2. This claim was regarded as blasphemy in that Jesus was making himself out to be God (10:33).
3. Jesus quoted Psalm 82:6 to establish he is justified; the law doesn't forbid his claim.
The common consensus of this quotation is that Jesus was arguing the law doesn't forbid calling a human a god, as Psalm 82 says humans are gods, thereby the law allows him to claim to be a god on the basis of Psalm 82:6. Irenaeus and Athanasius comport with a Biblically oriented theology based on ancient Israelite scriptures, such as Psalm 82.
Justin Martyr,
- "Let the interpretation of the Psalm be held just as you wish, yet thereby it is demonstrated that all men are deemed worthy of becoming “gods,” and of having power to become sons of the highest.... (Dialogue with Trypho)
Irenaeus of Lyon:
- "For we cast blame upon Him, because we have not been made gods from the beginning, but at first merely men, then at length gods; although God has adopted this course out of His pure benevolence, that no one may impute to Him insidiousness or grudgingness. He declares, “I have said, Ye are gods; and ye are sons of the Highest.” (Against Heresies, Bk. IV, ch. 38, sec. 4)
Clement of Alexandria:
- "Accordingly this grace is indicated by the prophet, when he says, “I said that ye are gods, and all sons of the Highest.” For us, yea us, He has adopted and wishes to be called the Father of us alone, not of the unbelieving." (Protreptikos 12)
- "Being baptized, we are illuminated; illuminated, we become sons; being made sons, we are made perfect; being made perfect, we are made immortal. “I,” says He, “have said that ye are gods, and all sons of the Highest.” (Paedagogus, Bk. I, ch. 6)
Clement of Alexandria uses Psalm 82 to show that our Biblical "sonship", in Christ, is synonymous with our becoming god. Hence, what it means to be a son of God, “we are the sons of God, and it doth not yet appear what we shall be: but we know that, when he shall appear, we shall be like him; for we shall see him as he is.” (1 John 3:2).
While Protestant Reformer Martin Luther, there is no separation of God’s person from his gifts. When he grants us the righteousness of Christ, he grants us Christ himself. When Luther speaks of our union with the divine, when Christ indwells us, there are traces of deification found in Luther passages that seem to support the Finnish Lutheran claim that deification as the exchange of our natures is at the center of Luther's theology.
In the Christmas sermon of 1514:
- "Just as the Word became flesh so is it necessary that the flesh become the Word. For the Word becomes flesh precisely so that the flesh can become Word. In other words, God became man so that man may become God. Thus power becomes powerless so that weakness may become powerful. The Logos put on our form and manner, image and likeness, so that he might clothe us with his image, form and likeness. Therefore, wisdom became foolish, so that foolishness might become wisdom. And so with regard to all other things that are in God and us, in everything he assumes ours, so that he might confer onto us his …"
From a 1525 sermon:
- "And so we are filled with “all the fullness of God.” This phrase, which follows a Hebrew way of speaking, means that we are filled in all the ways in which God fills; we are filled with God, and he pours into us all his gifts and grace and fills us with his Spirit, who make us courageous. He enlightens us with his light, his life lives in us, his beatitude makes us blessed, and his love causes love to arise in us. Put briefly, he fills us in order that everything that he is and everything he can do might be in us in all its fullness, and work powerfully, so that we might be divinized throughout"
In a 1526 sermon:
- “God pours out Christ His dear Son over us and pours Himself into us and draws us into Himself, so that He becomes completely humanified (vermzenschet) and we become completely deified (gantz und gar vergottet, “Godded-through”) and everything is altogether one thing, God, Christ, and you.”‘ (Martin Luther, D. Martin Luthers Werke. Kritische Gesamtausgabe, 58 volumes (Weimar, 1883- ), 20:229,30 and following, cited in Werner Elert, The Structure of Lutheranism, volume 1 (Saint Louis: Concordia Publishing House, 1962),175-176)
