Is the original pattern for the church still valid?
It was always in Jesus' plans to build His church. In the gospel of Matthew 16:18 it is recorded that Jesus said "I will build my church," However, Jesus did not personally establish congregations while He was here on earth. Rather, Jesus intended for this work to be done by the apostles after He had returned to heaven. Jesus promised to send the Holy Spirit from heaven into the apostles to guide them in this important work. In the gospel of John we read that on the very night that he was going to be arrested Jesus told his apostles, "The Holy Spirit, whom the Father will send in my name, will teach you all things and remind you of everything I have said to you (John 14:26)". The apostles established the first Christian congregation in Jerusalem approximately ten days after Jesus ascended back to heaven. This is recorded in Acts 2.
Later in the book of Acts you can read how the apostles and first Christians established more congregations in other cities and towns. The rest of the New Testament describes how these first congregations were organized, how they worshiped, what they taught and how the first Christians put their faith into practice in their daily lives. The apostle Paul wrote to the church in the city of Philippi, “join with others in following my example, brothers, and take note of those who live according to the pattern we gave you (Philippians 3:17)". Paul also wrote that, "what you have heard from me, keep as the pattern of sound teaching, with faith and love in Christ Jesus. Guard the good deposit that was entrusted to you (2 Timothy1:13-14)". And not only this, but Paul also said that, "All Scripture is God-breathed and is useful for teaching, rebuking, correcting and training in righteousness, so that the man of God may be thoroughly equipped for every good work (2 Timothy 3:16-17)". This means the Bible contains a complete message for us concerning what the church should be like and how we should live as Christians. If we follow these teachings in our personal lives, and organize our congregations in the same way that the first Christians did, we will be pleasing to God today just like the first church was.
