Ante-Nicene Fathers, Vol I: POLYCARP: The Martyrdom of Po...
The Church of God which sojourns at Smyrna, to the Church of God sojourning in Philomelium, 420 and to all the congregations 421 of the Holy and Catholic Church in every place: Mercy, peace, and love from God the Father, and our Lord Jesus Christ, be multiplied.
Some read, “Philadelphia,” but on inferior authority. Philomelium was a city of Phrygia.
39:421
The word in the original is ποροικίαις, from which the English “parishes” is derived.
