THE BODY OF CHRIST only has one sole mission, and it is a Soul Mission!  Based on the calling of Peter and Andrew, who were fishermen by trade, and were called by Jesus Christ to become Fishers of Men! 
Matthew 4:18-20 18
As Jesus was walking beside the Sea of Galilee, he saw two brothers, Simon called Peter and his brother Andrew. They were casting a net into the lake, for they were fishermen. 19 “Come, follow me,” Jesus said, “and I will send you out to fish for people.” 20 At once they left their nets and followed him.
