Hi Deb. I certainly don't find it offensivem but perhaps I'm not a good guage of such things. You might point out that the Shakers, who were certainly a somewhat puritanical lot (celibacy for all - new members were orphans they took in), firmly believed that God is neither male nor female. I don't know what they did about a pronoun, but the image of God as man/male was completely eschewed.
Hope that helps and good luck. lots of love Anne
