Our Purpose: Advancing the Cause of Christ The purpose of Trinity Presbyterian Church is to motivate the people of God toward a spiritually mature walk with the true and living God by teaching them the doctrines of God's word—using as a guide the Westminster Confession of Faith—so that they are equipped to infiltrate the world with God's truth in every sphere of life; and so that they are equipped to communicate the Gospel and disciple converts to the end that the kingdom of God is triumphantly expanded and the kingdom of the world diminished.
