Worship
is at the very heart of the church's life. All that the church is and does
is rooted in worship. The community of faith, gathered in response to God's
call, is formed in its worship. Worship is the principle influence that
shapes our faith, and is the most visible way we express the faith. In worship,
through Word and Sacrament, the church is sustained by the presence of Christ.
Joined in worship to the One who is the source of its life, the church is
empowered to serve God in the world.
