Christian tradition has always looked on heaven under the analogy of a city. Coelestis urbs Jerusalem.[…] It is a city compact like a single house; a close-knit society, gathered like one family under a singe roof […] but at the same time extended to the uttermost.[…] Among those who are received within this heavenly city there is a more intimate relationship than subsists among the members of a human society, for among them there is not only outward harmony, but true unity […], the very consummation of unity, both the image and the result of the unity of the Divine Persons among themselves.[…] The Christian mysticism of unity is trinitarian. The likeness, which in every created soul must be the completion of the divine Image, is not that of a Spinozist God; it is that of a God of Love, of the God whose being is Love.

To seek sincerity above all things is perhaps, at bottom, not to want to be transformed; it is to cling to yourself, to have a morbid love of yourself, just as you are, that is to say, false. It is to refuse release.
