John Myes wanted to know if the hagia in Hagia Sophia is related to the hagios in our Good Word hagiography. Hagia Sophia is the name of the museum in Istanbul that was once the seat of the patriarch (= pope) of Eastern Orthodoxy. Indeed, Greek hagia “holy” is the feminine form of hagios, which is also the word for “saint”, so Hagia Sophia means “Saint Sophia”. (We find the same relation in saint, which was originally Latin sanctus “holy”.)
I always thought it interesting that the patron saint of the Roman Catholic Church was a man, St. Peter, the Rock, while the patron saint of the Eastern Orthodox Church (once a part of the Roman Church), was a woman, St. Sophia, also the Greek word for ”Wisdom”.
The several historical attempts to (re)marry these two faiths have failed. They would seem to be incompatible despite all their common interests.
