A key difference

 A reader asked me what the correct pronunciation is of St. Malachi, the simple, beautiful Roman Catholic church tucked away in Londonderry Township. She had heard it pronounced both "Mala-KEY" and "Mala-KAI."
So I asked a friend who is a church member, and she told me it should be pronounced "Mala-KEY," after the Irish saint of the same name. "Mala-KAI" was a prophet and is the last book of the Old Testament.
