The other day in house group we studied Phil 1.1-11. One thing we didn't touch on was the interesting variant in v11: EIS DOXAN QEOU KAI EPAINON EMOI (P46; it/ar). Here is a picture of P46 at this point:
Considering this is the earliest manuscript (by far), and the most difficult reading, I wonder whether this could make sense as the original/Pauline reading. On this basis EPAINON here would refer to approval or recognition received from God (as generally in Rom 2.29; and specifically in connection with apostolic ministry in 1 Cor 4.5, BDAG has other refs). The general thought would reflect Paul's conviction that his own eschatological reward is connected with the perseverance of his churches (as e.g. 1 Thess 2.19f: 'For what is our hope or joy or crown of boasting before our Lord Jesus at his coming? Is it not you? For you are our gory and joy.'). The same idea (with quite different language) is present in Phil 2.16. So on this basis it seems possible to conceive of this reading as Pauline - not egotistical but eschatological. The righteousness of the Philippians comes through Jesus Christ, it brings glory to God, and it results (also) in eschatological reward for Paul. Silva pretty much accepts this view of things, but is rather cautious about adopting a reading on the basis of a single witness.
