A constitutional monarch of the United Kingdom, who must by law be a faithful Protestant, carries the titles “Defender of the Faith” and “Supreme Governor of the Church of England.” The oil used for the sacramental anointing of King Charles III was consecrated at the Anastasis, the Church of the Resurrection, by the Orthodox Patriarch of Jerusalem and the Anglican Archbishop. This ritual act placed the king within a subtle and complex set of historical and sacral relationships that link the British monarchy to the Orthodox monarchies of Russia and Greece and, through them, back to Byzantium and to Rome.
