I’m a simple guy so I look at it plainly. What is the church supposed to be and do? It seems like the Great Commission is the place to start:
“Go therefore and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, teaching them to observe all that I have commanded you. And behold, I am with you always, to the end of the age.”” (Matthew 28:19–20)
Disciples of Christ are to make disciples (evangelism), baptize them into the church, and teach them to learn and apply the Bible. Then the cycle repeats itself: evangelism, baptism, training.
