Nick Glowers has A Theology of Running Away, based largely on Athanasius:
The flight of the saints therefore was neither blameable nor
unprofitable. If they had not avoided their persecutors, how would it
have come to pass that the Lord should spring from the seed of David?
Or who would have preached the glad tidings of the word of truth? It
was for this that the persecutors sought after the saints, that there
might be no one to teach, as the Jews charged the Apostles; but for
this cause they endured all things, that the Gospel might be preached.
This is one means of defense that should be acceptable to all. Unfortunately, it is not completely effective, for Israel had to fight too.
