A distinction must be drawn between revision and review. Revision implies review as an antecedent step, but review is by no means necessarily followed by revision. The English book was reviewed and revised in 1662; it was reviewed but not revised in 1689. Review is tentative and advisory; revision is authoritative and final. In the present instance not an atom of power to effect binding change has been conveyed. No authority has been given to anybody to touch a line or a letter of the Prayer Book save in the way of suggestion and recommendation. Responsible action has been held wholly in reserve. Moreover, even the pathway of review was most scrupulously hedged. Applying to the resolution the legal maxim, _expressio unius est exclusio alterius_, one sees at a glance that doctrinal change is a matter left wholly on one side. The two points to which the Committee is instructed to bend all its studies are "liturgical enrichment" and "increased flexibility of use." Whatsoever is more than these is irrelevant. Accurate distinguishment between such "enrichments" as have and such as have not a doctrinal bearing is, no doubt, a delicate point, and must be set down among the difficulties to be encountered. As such it will be considered further on. For the present the fact to be noted is that the authorized reviewers are both in honor and in duty bound to keep themselves absolutely clear of controversial bias. The movement is not a movement to alter in any slightest respect the dogmatic teaching of the Church, not a movement to unsettle foundations, not a movement toward disowning or repudiating our past, but simply and only an endeavor to make the Common Prayer, if possible (and we are far from being sure, as yet, that it is possible), a better thing of its kind, more comprehensive, more elastic, more readily responsive to the demands of all occasions and the needs of "all sorts and conditions of men." Some who are deeply persuaded that only by doctrinal revision in one direction or another can the Prayer Book be made thoroughly to commend itself to the heart and mind of the American people will esteem the measure of change above indicated not worth the effort indispensable to the attainment of it. Be it so; other some there are who do think the attempt well advised and who are willing to waive their own pet notions as to possible doctrinal improvements of the book for the sake of securing a _consensus_ upon certain great practical improvements which come within the range of things attainable. Certain it is that any attempt of a body of reviewers like this to disturb, even by "shadowed hint," the existing doctrinal settlement under which we are living together, would be resented by the whole Church. There are divines among us who in the interest of a more sharply defined orthodoxy are conscientiously bent upon securing the reintroduction among our formularies of the so-called Athanasian Creed.
