Further reaction from the World Council of Churches can be seen at Church body wants Hagia Sophia decision reversed, and the Pope has come off the diplomatic fence to express his disapproval as in Pope 'pained' by Hagia Sophia mosque decision and Pope Francis ‘pained’ by decision to turn Hagia Sophia into mosque
The comment by the Pope in his Angelus address is indicative of the importance of the Turkish move. The Papal silence on the topic until then has drawn the fire the Greeks, as in this piece from an English language Greek newspaper which can be seen at The Pope Remains Silent On The Conversion Of Hagia Sophia
Hagia Sophia has witnessed so much since the time of Justinian that this latest decision is but one more episode in a long and turbulent history interspersed with earthquakes, renovations and restorations.
To return to my opening point the fact that this story is newsworthy and that it is attracting comments from the Phanar, the Vatican, the Moscow patriarchate and the WCC points to just how important Hagia Sophia is to Christendom, to Islam and to the world of culture. That fact is something to ponder - and in doing so it might indeed bring us a glimpse of Holy Wisdom.
