Well women with scarves on their heads? Catholics did that in the 5o's. No more? How come? Did the Law change? Now they go to mass on Sat night wearing shorts and jeans. Did the Law change? Call no man Father-- or Holy Father, lol
protestants did it through the 50s also, not sure why either of them stopped but in my church we don't just forget commandments...
IMHO and from what I've heard before, Father in this case means the same as Master and we're to call no man MASTER because God alone is Master. I don't know what the original language is but perhaps someone smarter than I will let us know.
