The biblical epic by the Spanish priest Juvencus is the first great piece of Christian literature in Latin. Heinsdorff provides a commentary on Christ's conversations with Nicodemus and with the Samaritan woman (John 3 and 4) from this biblical epic. In addition to providing an explanation of the theological statements in the text, the author also presents philological observations, which show the presence of both traditional epic elements and specifically Christian features in the language. The appendix gives a statistically evaluated collection of material which shows the strong European influence on the Latin text of the Bible.
