I skip most of the article because I'm only interested in the part that makes the least bit of sense:
While Peter is speaking, he is interrupted by the Holy Spirit pouring into the Gentiles in Cornelius’ house. The Jewish companions of Peter are amazed at what is happening. Arnold explains:The Torah-observant Jews recognize the remarkable significance of this event. God is now accepting Gentiles on the same basis that he did the Jews—on the sole basis of believing in Jesus Christ for the forgiveness of sins. These Gentile believers will not be required to be circumcised, offer sacrifices, observe the Jewish festivals, or keep Jewish dietary laws as a means of entering or maintaining their position in the new people of God.
Say what? How can acceptance of Gentiles at this point in Peter's life in Acts 10-11 be anything close to "epoch", when the 4 canonical gospels make clear that Jesus did a substantial amount of preaching among Gentiles? It is my contention that somebody is lying: If Jesus really had such a Gentile ministry, Gentile salvation would not have been regarded as a new theological development to Peter or the rest of the church as late in the game as Acts 10-11, so either a) the gospels are lying and Jesus preached only to Jews, or b) Acts is lying and painting Peter and the church as nearly universally Jew-oriented.Seeing this, Peter commands his companions to baptize these Gentiles in the name of Jesus Christ. Darrell Bock, in Acts, Baker Exegetical Commentary on the New Testament, summarizes:God directs an epoch-making event in which Gentiles are accepted in fellowship and receive the gospel.
Their faith leads to the gift of the Spirit, the sign that the new era has arrived. In addition, they are not circumcised and yet table fellowship and full hospitality between Jews and Gentiles ensues.
The Trinity is quite active here (Gaventa 2003: 173–74). God takes the initiative. Jesus Christ is at the center of the plan. The Spirit confirms that all of this is God’s work. The actions that take place represent the act and will of God working in harmony. The church does not lead here but follows God’s leading, thereby learning a great deal about how God views people.
