Christ the Lord - Out of Egypt
Ann Rice of Interview with the Vampire fame has written a book based on Jesus’ Egyptian boyhood. There is nothing on this in the gospels, other than an indication that Joseph fled to Egypt with his family and stayed there until after the death of Herod the Great. (Matthew 2:13-15) Rice made it all up, subject to what her research revealed about the time and place.
A greater constraint, if she was to be faithful to the gospel accounts, was to faithfully render what the Incarnate God would have been like when he was seven years old — or when his human nature was seven. Two blog reviews are of interest here, one because Ann Rice herself commented on the review, the other because it reviews the book in the context of Christianity’s relationship to the arts.
