"When we stood in the temple we hardly knew whether we were in heaven or on earth. For in truth it seems impossible to behold such glory and such magnificence on earth. We could not possibly relate to you what we saw in that place. But one thing we know, there God dwells among men, and all the worship of other countries is to us, forevermore, as nothing. We cannot forget that beauty which we saw. Whoever has enjoyed so sweet a sight will never be satisfied with anything else; nor will we consent to remain any longer in paganism as we are now.”
-The Russian Emissaries on their experience at the Hagia Sophia.
