The Church is all those earth and in heaven who have been called by God, through Jesus Christ, to be His people, and who share the unity that the Spirit gives. The Spirit guides the Church, and equips its members with varied gifts, so that they may support one another, encourage one another and serve their neighbours with joy. The universal Church takes the form of local congregations, where the message of Christ received through the apostles is preached, where God is glorified in the celebration of the sacraments and other acts of worship, and Christians share the Christian life.
