Union Among the Churches of the Anglican Communion - Encyclical Letter 1.6: Of Church Organization
Inasmuch as the sufficient and effective organisation of the several parts of the Church tends to promote the unity of the whole, your Committee would, with this view, repeat the recommendation in the sixth Report of the first Lambeth Conference, that those dioceses which still remain isolated should, as circumstances may allow, associate themselves into a province or provinces, in accordance with the ancient laws and usages of the Catholic Church.
[NOTE: The Lambeth Conference of 1878 did not adopt any formal Resolutions as such. The mind of the Conference was recorded by incorporating the Reports of its five Committees, received by the plenary Conference with almost complete unanimity, into an Encyclical Letter which was duly published. Recommendations embodied in the Committee Reports were evidently accorded equivalent status to formal Resolutions, and they are reproduced here as they appeared in the course of the Encyclical Letter, under appropriate reference.]
