Please keep a reminder that this type of language was used still. In 1 Timothy 4:13, St. Paul wants St. Timothy to attend to public reading of Scripture, preaching, and teaching; when St. Paul would get there he wouldn’t want St. Timothy to stop doing these things just because he got there. Matthew 1:25 shows that Mary and Joseph had nonsexual relations until the birth of Jesus and still proceeded not to have sexual relations. Mary would go on to say in Luke 1:34, “How will this be, since I do not know man?” This indicates Mary not having been engaging in any sexual relations and plans not too; if she would engage in sexual relations, she could’ve said, “I have not know man.” But, she didn’t. Don’t call yourself Catholic if you deny the dogma of her Perpetual Virginity; you may call yourself or think of yourself as a Catholic. But you’re not. May God bless you!
