My first instinct, when reading of the proposal that Moslems be allowed to worship in Cordoba Cathedral, on the grounds that they built it (on the site of a church which they had demolished), was: how right the Bishop of Cordoba is to refuse it. Celebrating the Eucharist in a former mosque can be a joyous experience; I remember, in Crete, many years ago, going to the Liturgy in the Church of S Titus, which still retained all the glorious architectural and decorative features of the mosque it had been (built on the site of a church). Rambling still further, I recall a superb Orthodox church on the waterfront at Rhodes, which was built by the Italians and, after the war, "purified from the dogma of the Latins" and adorned with superb murals in mid-Byzantine style. Rambling yet more inconsequentially, I remember the Hospital Chapel in Exeter; the area directly in front of the Aumbry, where the Blessed Sacrament was reserved, did additional duty as the area set aside for Moslem prayer and equipped with prayer-mats.
But then I wondered about the possibility of a world-wide game of musical chairs. Cordoba Cathedral, the Bishop of Cordoba could promise, would be handed over to the Moslems on the very self-same day when Hagia Sophia and all other sites in Constantinople originally devoted to Byzantine worship are restored to the See of S Andrew. Because that leaves us Latins rather disadvantaged ... as we so commonly seem to be ... we could be comforted by having a handful of the monasteries on Athos (where there were indeed Latin monks during the first millennium) handed over to us.
You know it makes sense.
