“Could this Artemis problem also be related to such things as
1 prayers for a quiet life 2:1,2 (in contrast to the riots of Acts 19)
2 Jesus is the one mediator v5 in contrast to the temple priestesses
3 Anger, fighting, disputing v8 ?”

I suspect much of this has to do with the heresies of gnosticism and the heresies of the Ephesus temple of ??? (forgot the name). Even verses 2:13-15 hint at correcting gnostic false teachings.
