Did the Jerusalem apostles lose their preeminence in God's program after the early days of Acts?

Les explains that Paul, by inspiration of the Holy Spirit, was not merely getting back at the Jerusalem apostles. Scripture says these who seemed to be somewhat no longer had the kind of authority they had in the early years; it was slipping away. God accepts no man's person, so in God's view Peter was no greater than anyone else. When Scripture repeats something in short order, Les says it is for emphasis, driving home that these men no longer had the preeminence of God's dealing with the human race that they enjoyed in the earthly ministry and early days of Acts. At the conference, those who seemed to be somewhat added nothing to Paul, because they had no comprehension of the revelations he received from the ascended Lord. They knew Jesus in the flesh and during the 40 days after His resurrection, but they knew nothing of the ascended Lord in glory, from whom Paul received all his revelations.
