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. III. The members of the Anglican Church have the same freedom as other Catholics in the matter of theological speculation. What was done at the Reformation was not final in the sense that we are never to believe or to teach anything that is not found in Anglican formularies. The fact that a certain doctrine like that of the Invocation of Saints was omitted from the Anglican formularies is not fatal to its practice. The grounds of its omission in practice may or may not have been well judged. But the theory of it was never denied, it is indeed contained in the Creeds themselves, and change in circumstances may justify its revival in practice.
