One of the most distinctive aspects of John's gospel is his presentation of Jesus' miracles as semeia – 'signs'. To get to the bottom of why John is so fond of semeia, Helen and Lloyd enter the time machine with leading Johannine scholar Catrin Williams. They discuss whether there are really seven signs in the gospel, how John's signs relate to scripture, and whether they are history or fiction.  

Catrin H. Williams is Professor of New Testament Studies at the University of Wales Trinity Saint David, Lampeter. A Fellow of the Learned Society of Wales, she has published extensively on the Gospel of John, including a 2025 co-edited volume The Semeia Narratives in the Gospel of John.
