Through Acts 1-15, God (primarily through the work of Peter, Paul and James) has removed His work out of the Judaistic mold, creating the Israel of God (the church) designed to spread to the Gentiles. Though certain ceremonial and civil aspects of the law were (for a time) suspended, the Law of God was never suspended, especially as it relates to defilement of conscience or disregarding of scruples that could cause permanent spiritual damage or unwittingly place one in communion with demons. We must always conduct ourselves with the long —term spiritual interests of others paramount on our minds, being sensitive to conscience and scruples of others as we exercise our 'rights.'
After explaining the context in which Paul advocated going from house to house, John Ritenbaugh reiterates that Paul, who understands clearly that God alone calls (John 6:44), makes his initial contact with non-believers in public places (synagogue and forum), going later to private dwellings by invitation only. Chapter 15 focuses upon the Council of Jerusalem, discussing the controversial subject of circumcision and its relationship to salvation. Peter, speaking from his experience working among the Gentiles, realized that some aspects of the ceremonial laws (including circumcision) were not obligatory to Gentiles for salvation, but that the entire Law of God (given by Jesus Christ), far from done away, is to be kept in a more responsible spiritual sense (respecting the boundaries or constraints of conscience) by both Jews and Gentiles. It had become apparent to the apostles gathered at Jerusalem that God had made a parallel visitation and calling to the Gentiles as He had originally concluded with Israel. The new spiritual tabernacle (the Israel of God) would be composed of Gentiles as well as people of Israel.
John Ritenbaugh focuses upon the intent or purpose of the scripture in Deuteronomy 23:2 prohibiting offspring from illegitimate unions (often carrying psychological baggage and irreversible physical damage) from holding offices of responsibility in physical Israel for ten generations. Acts 14 begins with the people of the Lycaonian cities of Lystra and Derbe mistaking Paul for Hermes and Barnabas for Zeus. When Paul convinces the crowds that he and Barnabas were not gods, they were treated with contempt rather than adoration. The church, it seems, has always been forced to live in hostile environments. At the beginning of chapter 15, the question is posed whether a Gentile must undergo circumcision in order to be saved or keep the law in order to become justified. Lawkeeping in the present does not justify past sins, nor is it intended to be a vehicle for salvation. This understanding does not do away with God's law, which must be kept in the spirit. Following the Council of Jerusalem, God now begins His spiritual work through the church, taking His Word out to the nations.
