According to the ridiculous Acts 28 theory, invented by Charles Welch in 1908—stating that Paul's ministry to the nations did not begin until he was an old man in prison in Rome, about to be martyred—the nations did not become one with Israel until this late date. The theory, however, collapses in the face of many passages in Paul's very early letters, such as this one in Galatians 3:27-28—

"For whoever are baptized into Christ, put on Christ, IN WHOM THERE IS NEITHER JEW NOR GREEK, there is no slave nor yet free, there is no male and female, for you all are one in Christ Jesus."

The nations being made one with Israel was an early reality already built into Paul's gospel, which the apostle began heralding back in Acts 13—not two decades later in Acts 28.

A careful reading of Ephesians chapters 2 and 3 reveal that Paul is REVIEWING the era when the nations WERE "alienated from the citizenship of Israel" (past tense; Ephesians 2:12). Thus, every time Paul uses the words "yet now" in this passage, he doesn't mean the moment he is writing, but is rather describing the era subsequent to "that era" (Ephesians 2:12)—the era before Paul's gospel started—that is, the current era that began at the same time Paul's gospel began, way back in Acts chapter 13.

The Acts 28 position is a construct, an artificial line invented so as to eliminate from the body of Christ important truths from Paul's early letters, such as the snatching away of the body of Christ (1 Thessalonians 4:13-17), and the great truth that "the era is limited" (1 Corinthians 7:29).

Those clutching desperately to the Acts 28 position do so to assure themselves of living a long, full life on this earth with their families. To them, the snatching away is a threat to their family plans here on earth.

Another way of saying this is that adherents to the Acts 28 position love the current eon.  

Happy Show 2000, folks.
