Some have asked that I summarize my earlier post defending eternal generation and arguing against ERAS, and do so by sticking primarily to exegetical and biblical theological arguments. I want to say at the outset that none of what I say below is without deep, deep roots in the historical tradition, nor is it my own ingenuity (not a shock to those that know me well). It is, rather, reliance on the history of interpretation without the footnotes. See my earlier post for those. I should also say that this will be relatively brief; all of the harder stuff has been covered for 1600 years. In any case, here it goes.
1. One God in Three Persons
We have to take a step back before jumping right in to eternal generation and/or eternal submission to see how we get to affirming the Trinity in the first place. The twin biblical affirmations that there is one God (Deut. 6:4) and that the Father, Son, and Spirit are each equally God because they share titles (Lord, God, Almighty, etc.), attributes (power, wisdom, etc.), and actions (creation, salvation) have to be reconciled. When we couple this with the radical distinction we see in Scripture between Creator and creature, there is no “mediatorial” option for Son and Spirit. Because they equally share in divine titles, actions, and attributes, and because there is no such category as a mediatorial being in the biblical worldview, the Bible demands acknowledging that these three are equally God while also acknowledging that there is only one God.
2. John 5:26 and “Life in Himself”
The question at this point, of course, is exactly how these three persons are distinct persons while also being one God. The testimony of Scripture is that they share equally in the essence of God – what makes God God is his essence, which is his authority, power, will, goodness, mercy, holiness, etc. So, for instance, Father and Son share equally in the creation and therefore in their authority over that creation (e.g. Col. 1:15-18). How, then, are they distinguished? Texts like John 5:26 give us a good start. The Father has life in itself, and gives the Son life in himself.
It is clear from the context that the Son is speaking of his equality with the Father in his divinity (namely in the actions of judging and raising the dead). Even if, though we want to say that he is expressing in this context how these characteristics work themselves out in his incarnate state, John 5:26 is set within the larger context of comparing the Father and the Son’s divinity. Further the phrase “life in itself” is hard to maneuver toward the incarnation. If this were referring to the incarnation, the text would be saying that the same kind of life the Father has, is now given to the Son in his becoming incarnate. How is that so? What exactly would it mean for the Father’s divine life to be the same as the Son’s incarnate life? It would make more sense, especially given the context, to say that the Father has life in himself – a characteristic that is only true of God – and has given the Son life in himself. The Father here communicates what it means to be God to the Son.
3. Proverbs 8 and the Father’s Begotten Wisdom
Proverbs 8:22-31 is notoriously difficult, especially for modern readers. But when we think canonically, it becomes a bit clearer. Christ is clearly identified as the Wisdom of God (1 Cor. 1:24) and, synonymously, the Word or Logos of God (John 1:1-13). He is the one through whom the Father creates (Col. 1:15-18). For Prov. 8:22-31 to be speaking of anyone but the Son, therefore, would make little sense of this New Testament usage. Further, for the Father in Proverbs 8 to have some wisdom other than the Son would make little sense, either. We thus have to deal with Proverbs 8:22-31 that makes sense of how God can “birth” his Wisdom before time began and therefore before he actually creates anything. Now, with John 5 and Proverbs 8, we have two texts that give us “generating” language to speak of the relationship between Father and Son.
4. Names: Father, Son, and Spirit
Perhaps even more importantly than individual texts is the pattern of texts we see throughout Scripture, a pattern that consistently names these three as Father, Son, and Spirit. This points not only to their triunity but to the way that triunity exists, namely through a Father-Son-Spirit relationship. Now here we have to make a choice. What does it mean for their to be a Father-Son relationship? And this really is the rub. Does it mean, as the tradition has consistently argued, that the Father begets, or generates the Son? Certainly this is true of the analogy the language is using, human fatherhood and sonship. A son is typically a son through receiving his human essence via the father’s generation. But, on the other hand, another characteristic of many father/son relationships is that of authority and submission (so, today’s ERAS camp). So, how do we choose between the two? While I could give you the historical logic here (which, btw, did not include ERAS as an option), I’ll stick with my biblical guns and go to a particular text.
5. Phil. 2:5-11 and the “Form of God”/Form of a Servant” Pattern
Phil. 2:5-11 gives us explicit language with which to deal with not only passages that seemingly subordinate the Son, but also with how to adjudicate what Father/Son means by ruling out the ERAS option. This passage begins by noting that Jesus, prior to his incarnation, was “in the form of God.” This is not saying the Son was some sort of demigod, or lesser than God, but that he was in his essence, his form, truly God. Prior to his economic work of salvation as most fully seen in his incarnation, the Son is to be spoken of as in the “form of God.” But when he becomes incarnate, he takes on the “form of a servant.” Notice here that the point at which the Son becomes a servant – becomes submissive -to the Father, is at the incarnation.
Now, we have to of course deal with the eternal decree and, perhaps, the pactum salutis, but if we think of these as conditional, and not necessary, actions in God’s life – in other words, God didn’t have to save us and so his choice to do so is not fundamental to his eternal nature – then it is clear that the submission of the Son belongs to God’s life in the economy of salvation, his action of redemption, and not prior to it. There is no submission of the Son prior to his work of redemption. Therefore when we see texts that talk of Christ’s (or, in 1 Cor. 15:28’s unique case, the Son’s) submission (e.g. 1 Cor. 11:3), Paul in Phil. 2:5-11 gives us the exegetical key. These passages are not, according to the “form of God”/”form of a servant” pattern in Phil. 2:5-11, speaking of the Son’s eternal life with the Father but of his submission to the Father in the economy of salvation.
There are of course more issues that need to be discussed here. I’m not trying to cover them all; Luke and I have attempted some of that in the many posts we’ve written over the last three weeks. But that’s about as succinct a summary I can give for the biblical case for eternal generation (and against ERAS).
