This book is not controversial. In these days of unbelief we are only too glad to recognize believers in Christ, whatever degree of faith they may have attained. By whatever name nonconformist and sectarians call themselves, we recognize all baptized and faithful followers of Christ as Christians. The sins of former generations which rent us apart will not make us guilty of schism if we do not refuse enlightenment and seek for reunion. We recognize, on the other hand, the Orthodox Churches of the East and the Roman Catholic as portions of the Church of Christ and their members as our fellow churchmen. They are most potent agencies in the preservation of the Christian religion. In the devotion of their members we recognize a zeal we might well emulate. We gladly welcome all acts of Christian recognition on their part and are ready to reciprocate them. Our Church accepts their orders and places no barriers in the way of intercommunion.<br><br>Our purpose in writing is to offer some help, if by God's grace we can do so, to any who, as they say, wish to believe but cannot; or, believing in God and Christianity, are for any cause in doubt as to their duty respecting church membership. There are, we know, many such.
