EWTN Catholic Q&A
Assembly of Satan..
Question from Larry on 11-28-2012:

Father you recently answered a question where as some one asked about the assembly of Satan mentioned in Revelation. You implied it was spiritual so i'm curious as to your answer as there was a literal place in Greece called Satan . So i always assumed John was was being told that in comparing the type of people who gathered at the place of Satan.

Answer by Fr. John Echert on 11-28-2012:

I am not aware of this geographical location in the ancient world know as Satan. I have not found reference to this among early Church Fathers. The context and other Pauline references strongly suggest a spiritual interpretation.

Thanks, Larry

Father Echert
