By Dewey Roberts - Posted at Vanguard Presbyterian Church: How large were the churches in the New Testament? What was the membership of the church at Corinth? Or at Ephesus? Or at Rome? Or even at Antioch or Jerusalem? Do we know? Do we have any way to know? The Scripture never really gives us that information. We know that there were 3,000 people converted to Christ at the Feast of Pentecost, but they represented many different regions and countries—from Parthia, Media, Elam, Mesopotamia, Judea, Cappadocia, Pontus, Asia, Phrygia, Pamphylia, Egypt, Libya, Cyrene, and Rome. That is a very large geographical area represented by the converts. We know that there were about 120 believers who gathered in the Upper Room after Jesus’ resurrection. There were over 500 people who saw Jesus ascend into heaven 40 days after His resurrection. There were about 5,000 men who believed as a result of Peter’s second sermon in Jerusalem. Many of those were probably Jews who lived in Jerusalem or Israel
