The story of the word

William Penn named his city in 1682, but the name was already old. A Philadelphia in Asia Minor, one of the seven churches addressed in Revelation, had been founded by Attalus II of Pergamon, whose epithet Philadelphus was earned by declining to seize the throne while his brother Eumenes lived. The Greek compound is plain enough, and the New Testament uses φιλαδελφία for love among fellow believers rather than blood kin.
