Mentioning Aphia as an addressee of the Letter to Philemon is an important part of considering women’s duties in the early Christian communities. It turns out, that in spite of the role as housewives and mothers frequently assigned to them, some of them became also close and important co-workers of St. Paul. Therefore, contrary to certain opinions of feminist theologians, the Apostle of Nations seems to be the least chauvinist writer of his age. In addition to Apphia, who undoubtedly played an important role in the life of community gathering at Philemon’s home, it is also necessary to mention Priscilla (Acts 18 : 1 ff.), Lydia (Acts 16 : 11–14 ff.) and Phoebe (Romans 16 : 1 ff.). They were St. Paul’s closest collaborators. The service of these women shows that thanks to Christianity, contemporary social divisions had been overcome. The divisions have completely lost their significance or have changed their character, due to overworking them in the spirit of Gospel.
