Christian Church: It's Origin
The Christian Church was a "mystery" hidden throughout the Old Testament of the Bible. Later, Jesus first prophesied the coming of the church when He spoke to Peter and declared, "On this rock I will build My church" (Matthew 16:18). Here, Jesus is making a play on words, since he earlier changed Peter's name from Simon to Peter, which means "rock." The traditional view of when the Christian Church actually started was the Day of Pentecost (50 days after the Passover during which Jesus was crucified). It was at this time that Peter gave his great sermon, and in response, "about 3,000 souls were added to them [the apostles]" (Acts 2:41). This group of believers was first called "the church" in Acts 2:47, as "God added to the church daily those who were being saved."
