Our Leadership

"And he gave the apostles, the prophets, the evangelists, the shepherds and teachers, to equip the saints for the work of ministry, for building up the body of Christ, until we all attain to the unity of the faith and of the knowledge of the Son of God, to mature manhood, to the measure of the stature of the fullness of Christ". (Ephesians 4:11-13)


Cornerstone is led by a pastoral staff team of four members. The pastoral staff is responsible for the preaching and teaching of the Word of God, administering the sacraments, providing missional leadership, and faithfully carrying out pastoral care and work.
