Wrong. One becomes a part of the body of Christ by putting their faith directly in Him. Nothing can be added on or taken away from the salvation that comes through Christ death, the shedding of His blood for us on the cross. We become a part of The Church which is The Body of Christ only when we come to Christ Himself for salvation.
