With what were Peter and John still associated in the early part of Acts?
In the early part of Acts, Peter and John were still associated with the Judaism that Christ dealt with and John the Baptist preached—the Kingdom of Heaven message of repentance and baptism. They had no knowledge of the Church, the Body of Christ, but remained linked to that earlier kingdom program.
Les explains that Peter and John did not have any knowledge of the Church, which is the Body of Christ, in the early part of Acts. Instead, they were still associated with the Judaism that Christ dealt with and that John the Baptist preached—the Kingdom of Heaven, repent and be baptized. This indicates that Peter and the eleven men were still connected to that kingdom message at that time.
