We feel that other churches must accept, as the pre-conditions of fellowship, such changes as will bring them into conformity with ourselves in matters which we regard as essential, and that a failure to insist on this will involve compromise in regard to what is essential to the Church's being. But for precisely the same reason, we cannot admit a demand from others for any changes in ourselves which would seem to imply a denial that we already possess the esse of the Church.
