"And it is he who gifted some to be apostles, others to be prophets, others to be evangelists, and still others to be pastors and teachers, to perfect the saints, to do the work of ministry, and to build up the body of Christ until all of us are united in the faith and in the full knowledge of God's Son, and until we attain mature adulthood and the full standard of development in Christ." (Ephesians 4:11-13)
