Richard Mayhue asserts, "Furthermore, never in the whole New Testament is 'Israel' ever called 'the church'" (page 82).
This is patently false. Stephen refers to Israel as the church in his sermon:
"This is the one who was in the congregation in the wilderness together with the angel who was speaking to him on Mount Sinai, and who was with our fathers; and he received living oracles to pass on to you" (Acts 7:38).
"The congregation" is the Greek word, ekklesia, which is the word for the church. Thus, Stephen calls Israel the church.
So, whenever you find yourself listening to a Dispensationalist wax eloquent about how Israel is never called the church, simply ask, "What about Acts 7:38?"
