The same ambiguity exists in English! Let's get back to the Greek, shall we? Here's what the
Expositor's Greek Testament comments on Ephs 2:20:
"The gen. is variously understood as (1) the gen. of apposition = the foundation which is or consists in the Apostles; (2) the gen. of originating cause = the foundation laid by them; (3) the possess. gen. = “the Apostles’ foundation”—in the sense of that on which they built (Anselm, Beza, etc.), or as = that on which they also were built (Alf.). The choice seems to be between (1) and (2). The former has been the view of many from Chrys. down to Von Soden and Abbott, and is favoured so far by
Revelation 21:14. But the second has the suffrages of the
majority of modern exegetes (Rück., Harl., Bleek, Mey., Ell., etc.). It is more in accordance with
1 Corinthians 3:10 (although it is the worth of teachers that is immediately in view there), and more especially with
Romans 15:20, where the Gospel as preached by Paul appears to be the “foundation”. Here, therefore, it seems best on the whole to understand the Gospel of Christ as preached by the Apostles to be the “foundation” on which their converts were built up into the spiritual house."
That's an authoritative source. According to the above:
(1) The majority of Greek scholars side with MY reading of the verse, not yours.
(2) My reading best fits with the OTHER statements Paul made about "foundation". And that was my argument. Any unclear passage should be understood in terms of those more clear. So I addressed the clear verses - and you simply ignored them. How convenient.
At what point will cessationists admit that Cessationism is just a cover-up for the embarassment that the church, historically, has failed to reproduce apostolic success. Jack Deere - a famous cessationist scholar who later turned continuationist - later confessed, "I was a cessationist because there were no miracles in my life and I needed an excuse to explain away my lack of NT spirituality" (that's a paraphrase because I don't have his exact quote handy).
