This the attitude of the Anglican Church of the past is its attitude to-day. The Lambeth Conference of 1920 gave voice to it:
"The Conference urges on every branch of the Anglican Communion that it should prepare its members for taking their part in the universal fellowship of the re-united Church, by setting before them the loyalty which they owe to the universal Church, and the charity and understanding which are required of the members of so inclusive a society."
Commenting upon this utterance of the Lambeth Conference the three bishops who are the joint authors of "Lambeth and Reunion" say:
The bishops at Lambeth "beg for loyalty to the universal Church. The doctrinal standards of the undivided Church must not be ignored. Nor must modern developments, consistent with the past, be ruled out merely because they are modern. Men must hold strongly what they have received; but they must forsake the policy of denying one another's positive presentment of truth. That only must be forbidden which the universal fellowship cannot conceivably accept within any one of its groups[5]."

The bishops just quoted add: "We rejoice indeed at this new mind of the Lambeth Conference." Whether it is a new mind in Lambeth Conferences we need not consider; it is certainly no new mind in the Anglican Church, but is precisely its characteristic attitude of not claiming perfection or finality for itself, but of looking beyond itself to Catholic Christendom, and longing for the time when reunion of the churches which now make up its "broken unity" will enable it to speak with the same voice of authority with which it did in its primitive and undivided state.
In attempting to decide what as a priest of the Anglican Communion one may or may not teach or practice, one is bound to have regard, not to what is asserted by anyone, even by any bishop, to be "disloyal" or "unanglican," but to the principles expressed or implied in the utterances of the Church itself. From those utterances as I have reviewed them, it appears to me that a number of general principles may be deduced for the guidance of conduct.
I. The Churches of the Anglican Communion are bound by the entire body of Catholic dogma formulated and accepted universally in the pre-Reformation Church.
The Anglican documents, to be sure, speak constantly of the "Primitive Church," but they do not anywhere define what they mean by that; and frequently, by their appeal to the "undivided Church," and to "general Councils," they seem to include in their undefined term much more than is commonly understood. In any case, the Church has no special authority because it is primitive: its authority results not from its being primitive but from its being Church. The only point of the Anglican appeal would be the universal acceptance of a given doctrine. Such universal acceptance must be taken as proof of its primitiveness, that is, of its being contained, explicitly or implicitly, in the original deposit of faith. The Anglican Church was content with the summing up of this Faith in the Three Creeds, and attempted to formulate no new Greed of her own--the XXXIX Articles are not strictly a Creed: they are not articles of Faith but of Religion. But the very history of the Creeds implies that they are not final, that is, complete, but that they are a summing up of the Catholic Religion to date. There are truths which the circumstances of the Church in the Conciliar period had not brought into prominence which later events compelled the Church to express its mind upon. Such a truth is that of the Real Presence of our Lord in the Sacrament of the Altar. This truth had attained explicit acceptance throughout the Church before the Reformation, sufficiently witnessed by the liturgies in use. It is also embodied in the Anglican liturgy. If anyone thinks the language of the Anglican Church doubtful on this point, the principles enunciated by the Church compel interpretation in accord with the mind of the universal Church. There are other truths which are binding on us on the same basis of universal consent, but I am not seeking to apply the principle in every case but only to illustrate it.
II. There is another class of truths or doctrines widely held in Christendom, which yet cannot be classed as dogmas of the faith. Such a doctrine is that of the Immaculate Conception of the Blessed Virgin Mary. This doctrine has been made of faith in the Roman communion, but has not yet ecumenical acceptance, and therefore may be doubted without sin by members of the Greek or Anglican Churches. What we need to avoid, as the Lambeth Conference has reminded us, is a purely insular and provincial attitude in relation to doctrines which have not been formally set forth by Anglican authority. The Anglican Church has tried its best to impress upon us that there is no such thing as an Anglican Religion; there is but one Religion--the Religion of God's Catholic Church. What we are to seek to know is not the mind "of the Anglican reformers," or the mind "of the Caroline divines," but the mind of the Catholic Church. Wherever we shall find that mind expressed, though in terms unfamiliar to us, we are bound to treat it with respect. We are to seek to know the truth that the truth may make us free--from all pride and prejudice, as well as from heresy and blasphemy. And we shall best come at this mind in its widest meaning by the study of the writings of the saints of all ages and of all parts of the Church. It may fairly be inferred that those who have attained great perfection in the Catholic life have achieved it by the application of Catholic truth to every day living.
