My opinion is that a Christian man should always treat women with the utmost respect and propriety. Even Jesus treated Mary Magdalene, the prostitute in a very dignified and compassionate manner. How much more should a woman of God or a woman of good moral character be treated? 1 Timothy 5:2 ESV says "Older women as mothers, younger women as sisters, in all purity."
