Again, I’m not saying the crozier had a pagan precursor, but even if it did, that shouldn’t bother us. The Catholic and Orthodox Churches stretch back two thousand years, so incorporation and evolution within other cultures seems more foreign to us nowaways, especially when such cultures are still expressed (say, Latin in liturgy, or Eastern iconography in a Byzantine church).
But the fact is, ALL Christian traditions do the same thing – they take things from the surrounding culture (be it music or art or symbolism or clothing or concepts or language) and incorporate it and make it Christian.
It just doesn’t seem as odd or foreign or “pagan” when the Protestant church down the street does it, because that Protestant church is likely very new.
