Origin

The story of Sofia

Sofia keeps 17 September — the Martyr Sophia, remembered at Rome with her three daughters, Faith, Hope and Love.

The name is a word before it is a saint. Σοφία simply means “wisdom” — the same wisdom the great church of Constantinople, Hagia Sophia, was raised to honour.

“Wisdom.”
