It would be a poor self-conceit in the framers of _The Book Annexed_, that should prompt them to resent as intrusive any criticism whatsoever. What we all have at heart is the bringing of our manual of worship as nearly as possible to such a pitch of perfectness as the nature of things human will allow. The thing we seek is a Liturgy which shall draw to itself everything that is best and most devout within our national borders, a Common Prayer suited to the common wants of all Americans. Whatever truly makes for this end, it will be our wisdom to welcome, whether those who bring it forward are popularly labelled as belonging to this, that, or the other school of Churchmanship. To allow party jealousies to mar the symmetry and fulness of a work in which all Churchmen ought to have an equal inheritance would be the worst of blunders. By all means let the raiment of needlework and the clothing of wrought gold be what they should be for such sacred uses as hers who is the daughter of the great King, but let us not fall to wrangling about the vats in which the thread was dyed or the river bed from which the gold was gathered. In a later paper the present writer intends to venture upon a task similar to that undertaken by the Maryland Committee. He will do this largely in the hope of encouraging by example other and more competent critics to busy themselves in the same way. Meanwhile a few observations may not be amiss with respect to the sources of liturgical material, and the methods by which they can be drawn upon to the best advantage.
