With the history of the Turkish government, I doubt this would actually happen anytime, but I wanted to present a hypothetical situation.
Hagia Sophia is a museum, and probably will remain so for a long time. But what if the Turkish government decided that it could be used at certain times of the year?
For example, say they tell the Patriarchate that it can hold a service there once a year, possibly just the Paschal Liturgy. But, at the same time, they allow Muslims to hold prayer services there during Ramadan.
It is a big IF and a very unlikely hypothetical situation, but if this situation indeed arose, should we accept?
Or, say that they allow the building to be "rented" out for certain events, such as concerts or religious services, should we jump at the opportunity to celebrate Pascha in Hagia Sophia, even if other religious services and concerts are being held there, or even if we have to pay to worship there and even though the Islamic items and furnishings will remain?
