According to scripture every believer should be a part of a local assembly. As with those of like faith to be a part of the Progressive family you must first be a part of God’s family. The true church is those who have been born again. There are three modes of uniting with this fellowship. For new converts after confession of faith you may unite as a candidate for baptism (an outward expression of your union with Christ). For those who are relocating from congregation to another you may unite by letter or expression of your Christian experience.
