Our purpose as baptized members of Christ's Church is to respond in faith to the call of the Holy Spirit through the Gospel and unite together to preach the Word, administer the Sacraments, and carry out the work of God's kingdom. The work of the kingdom includes calling others to Christ and helping those in need.
Romans 15:5-7
May God who gives patience, steadiness and encouragement help you to live in complete harmony with each other, each with the attitude of Christ toward the other. Then all of us can praise the Lord together with one voice, giving glory to God, the Father of our Lord Jesus Christ. So warmly welcome each other into the Church, just as Christ has warmly welcomed you; then God will be gloried.
