For [it is] by grace you have been saved through faith, and this [is] not from yourselves, [it is] the gift of God, [it is] not from works, so that no-one may boast. For we are his handiwork, created in Christ Jesus for good works, which God prepared beforehand, so that in them we might walk. (Eph 2:8-10, my translation)
Ephesians 2:8-10 is well-known as Paul’s doctrine of salvation in miniature. Reformed Evangelicals love this passage, using it to explain what sits at the heart of the gospel—the relationship between grace, faith, and works in salvation. J C Ryle was converted simply by hearing it read in church. It’s a key passage in the popular Just For Starters: Seven Basic Bible Studies. Many of us have put together the puzzle of ‘grace’, ‘faith’ and ‘works’ from Ephesians 2:8-10. The paradigm ‘Not Saved By Works But For Works’ is a vital component of the excellent ‘Christianity Explained’ course, and rests on this passage. Indeed, the current de-emphasis on this in some circles blunts the cutting edge of the gospel.
I grew up Roman Catholic, wondering how I could be good enough for God. Then at university an MTS worker did Just For Starters with me. We opened the Bible, and in that hut at Kensington, I got God’s grace. I realised that my acceptance before God at the judgement is not based on my goodness or moral effort, but on God’s goodness and Jesus’ moral effort. I discovered that I’m saved, not by good works, but for good works. God even gave me the faith that joins me up to Jesus. God predestined the good works that he has now given me to do.
This little passage became the reason to find a Protestant church, go to beach mission, and arrogantly share the gospel of free grace. Even now, I continually return to this beautiful simplicity, because I’ve never graduated beyond my debt to grace, no matter what I think I’ve achieved. As Theodoret said, ‘I own myself wretched—aye, thrice wretched. I am guilty of many errors. Through faith alone I look for finding some mercy in the day of the Lord’s appearing.’
A Disconcerting Surprise
However, I came to discover with surprise and disappointment that many didn’t understand these verses ‘my’ way. Reading commentaries and learning Greek revealed that—in technical language—the demonstrative translated ‘this’ (v8) is neuter, but the noun for ‘faith’ is ‘feminine’. For my naive view to stand, they should agree—but they don’t. My Greek textbook declared, ‘On a grammatical level, then, it is doubtful that either “faith” or “grace” is the antecedent of [touto].’ Was this the death knell to my beloved understanding of Ephesians 2:8-10?
Further reflection yielded other questions. For example, verse 9 doesn’t say ‘good works’ but ‘works’—the adjective ‘good’ is only found in verse 10. So are ‘works’ (v9) the same as ‘good works’ (v10)? Are the works we are saved for different from those we are not saved by? Many say ‘yes’. Some limit the non-saving ‘works’ to ‘pre-baptismal’ ones, but then say that ‘post-baptismal’ works actually do save us. Or does verse 9 merely exclude from saving efficacy ‘ceremonial works’ or ‘Jewish boundary markers’? So are we saved by ‘good works’ after all?
Furthermore, in Ephesians, Paul doesn’t use the ‘justify’ words at all—although Protestants often assume it does. Is it a sound assumption? And what about the relationship between ‘not from yourselves’ (v8) and ‘not from works’ (v9)? What could it mean to say that ‘faith’ is ‘not from works’? And is it true to say that God has predestined our specific and individual ‘good works’? After all, the divine pre-preparation may simply have been God commanding them.
I don’t want to imply that I experienced some terrible existential crisis. I knew that other passages taught that our believing response to God is enabled by God if this one didn’t (see e.g. Acts 5:31, 11:18, 13:48, 16:14). But that didn’t mean I was eager to surrender a reading that had been so important to my early faith. And now I believe that there are good reasons to think that my naive understanding was right after all.
First, Classical Greek literature, the Septuagint, and the New Testament, provide evidence that ‘this’ can indeed refer to ‘faith’. There are 15 certain or highly probable examples of this rule—ten in the classical literaturę, four in the Septuagint, and one in the Greek New Testament.
Second, many ancient exegetes take it that way. As Abraham Kuyper observes:
Nearly all the church fathers […] judged that the words “it is the gift of God” refer to faith […] this was the exegesis […] of those that spoke the Greek language and were familiar with the peculiar Greek construction. 
I can confirm Kuyper’s assertion. Only a minority of ancient commentators associate ‘this’ exclusively with salvation, eight ancient exegetes specifically assert that ‘this’ refers back to a feminine noun in Ephesians 2:8-9, seven taking touto to refer to ‘faith’ (Chrysostom, Jerome, Augustine, Theodoret, Fulgentius, Œcumenius, Theophylact), and one taking it to refer to ‘grace’ (John of Damascus). These interpreters were either native Greek speakers or, in the case of Jerome and Fulgentius, Latin speakers of undoubted Greek ability, or, in the case of Augustine, the greatest extant theologian of the first Millennium.This is doubly important because the ancient Greek-speaking exegetes themselves were inclined to see faith as a human work. They thought human free-will had a controlling place in salvation, and that predestination was simply God foreseeing human virtue. Their exegetical decisions thus were generally in spite of, rather than because of, their theological commitments.In contrast with the ancients, most modern interpreters believe the ‘gift of God’ is the concept ‘salvation by grace through faith’. This is quite acceptable in terms of grammar. Calvin adopted it, and is followed by ‘the great majority of modern commentators’. Only three ‘modern’ commentators agree with the incumbent ancient understanding, and they all died last century! However, 19th century Greek grammars, steeped in the Classical literature from which Koinē Greek developed, articulate the rule that a neuter demonstrative can refer back to a masculine or feminine word. Modern commentators sometimes acknowledge this.
Expository Considerations (Ephesians 2:1-10)
The trajectory of verses 1-7 is not that humans under sin are sick and impaired but dead and enslaved. We were ‘dead’ in our ‘transgressions and sins’ (v1), and Paul includes himself with us in that plight (v5). Every human at one time has walked according to the world, the flesh, and the devil (vv2-3), and this requires that God must make us alive in Christ (v5) if we are to exercise faith (v8).
The clause ‘by grace you are saved’ explains ‘he made us alive with Christ Jesus’ (v5). So ‘making alive’ is part of God’s salvation by grace. ‘By grace you are saved’ appears again (v8), but a new, human element is introduced—‘through faith.’ This makes it more likely that the new element, ‘faith’, is the subject of verse 9. That is, Paul has already explained that clause (vv5-7). But the new element, ‘through faith’ (v8) most needed the explanation of verses 8-9. Lest his readers think faith is some independent action on the part of the subject, the Apostle puts it more starkly—‘faith’ is in one sense ‘not from ourselves’, though from another perspective, ‘faith’ is obviously from ourselves. And if ‘faith’ is the gift of God, so too is ‘grace’ and ‘salvation’. It cannot be otherwise. As Œcumenius said, ‘for us to believe [is the] gift of God, and to be saved through faith [is the] gift of God’. It is not ‘either/or’ but ‘both/and’.
The Eastern theological tradition considers that the divine cause of faith is adequately explained by God’s initiative-taking in the incarnation and gospel-preaching (Romans 10:14; Chrysostom; Œcumenius). This leaves room for free-will in the scheme of salvation, where grace is ‘fellow-worker’ (synergos) with free-will. It is synergistic.
By contrast, mature Augustinianism holds that the impulse by which we seek God is itself given to us by God. ‘[W]e receive, without any merit of our own, that from which everything … has its beginning— that is, faith itself.' Likewise, Fulgentiussays ‘and, since this faith is divinely enabled, it is without doubt bestowed by his free generosity’. It is not only the divine invitation to, but the divine enablement of, faith, that more accurately accords with faith being ‘the gift of God’.
Meanwhile, the Eastern tradition tends to take ‘not from works’ to refer to salvation—even though it takes ‘the gift of God’ to be ‘faith’. However, we might consider that ‘faith’ is ‘not from works’ in that no works merit the divine granting of faith. Works are not a condition of the gift of faith. This is how Augustine reads it: ‘And again, lest they should say they deserved so great a gift by their works, he immediately added, “Not of works, lest any man should boast”.’
What ‘works’ is Paul talking about? Barclay rightly says that the ‘works’ of verse 9 are ‘moral achievements’, and should not be limited to Jewish practices and cultural markers.  Even if we did see ‘works’ (v9) as essentially equivalent to the expression ‘works of the law’ in Romans and Galatians, the ‘works of the law’ would still be ‘good works’, as the stipulations of the law of Moses are ‘holy, righteous, and good’ (Romans 7:12). And what the law brings is not a ‘knowledge of Jewishness’ but a ‘knowledge of sin’ (Romans 3:20). ‘Works of the law’ requires human achievement, because ‘doing’ is the basis of justification by law (Romans 2:12-13, 7:10, 10:5; Leviticus 18:5). The ‘works’ promised to be rewarded at the judgement with eternal life for those who have not sinned but have done the law are ‘good works’ (Romans 2:6-7, 12-13). So ‘works’ (v9) should not be distinguished from ‘good works’ (v10), or limited to pre-conversion works, ethnic boundary markers, or ceremonial Jewish works. ‘Works’ are ‘human achievements’, ‘human effort’, ‘good works’, plain and simple. These ‘good works’ are the purpose of our creation in Christ Jesus—not its basis. Photius of Constantinople, taking ‘works’ (v9) and ‘good works’ (v10) as effectively the same, observes:
But even when we were created for good works, not only have we done nothing good, but we have even returned the very opposite […] But this, being created for good works, is at one and the same time both urging us forward to do [good deeds] and standing [us] apart from good deeds.
‘Standing us apart from good deeds’ can only be a reference to ‘not from works’ (v9). Photius thus equates ‘good deeds’ with ‘works’. Though we have been created for good works, we have done nothing good. Thus, Ephesians 2:8-10 teaches that we are not given saving faith by good works, but with the purpose that we do good works. The works that we are not saved by, these very same works we are saved for. ‘Good works are never the cause of salvation but ought to be its fruit’.
Verse 10 also teaches that God has prepared beforehand these ‘good works’. The prefix pro— is used in Ephesians 1:4, 5, 9, 11 to connote a divine decree before the foundation of the world. Giving pro— the same meaning in Ephesians 2:10, means that God predestined and prepared the specific good works to those to whom he gives faith. The good works do not derive from the believer as they are planned and purposed by God, and therefore they cannot be said to merit salvation or faith. Unsurprisingly, the word translated ‘prepared beforehand’ also appears in Romans 9:23, in a context which suggests divine predestination.
Interestingly, Paul doesn’t use ‘justification’ terminology at all in these verses. The closest we get to it is ‘seated with Christ’ in the heavenlies—clearly a positional category (v6). This is important, reminding us that ‘salvation’ is a broader idea that can encompass other teachings such as predestination, regeneration, sanctification, and rescue from punishment, whereas ‘to justify’ is a more limited forensic category meaning ‘to declare righteous’.
The elderly Bishop Augustine effectively united the majority Eastern exegesis of Ephesians 2:8-10 with a theological underpinning that gave this exegesis its natural home. Augustine’s rejection of the near universal view of predestination according to foreseen virtue and embracing of absolute predestination made him the first thorough-going monergist. His soteriology was more consonant with the interpretation of Ephesians 2:8-9 found in the East.
Regarding ‘faith’ as the ‘gift of God’ in Ephesians 2:8-9 has ample support to merit the label ‘catholic’, even if the mature Augustinian doctrine of predestination does not.
Learning these things from both the Eastern and Western exegetical traditions concerning Ephesians 2:8-10 enables us to be ‘more Calvinistic than Calvin’, who thought it an error to say that ‘faith’ was the gift here. But it is quite acceptable according to the rules of Greek syntax. Our modern grammars and commentaries should be revised to reflect that reality.
