Holy Lance
The name of the soldier who pierced Christ's side with a "lonchē" is not given in the Gospel of John, but in the oldest known references to the legend, the apocryphal Gospel of Nicodemus appended to late manuscripts of the 4th century "Acts of Pilate", the soldier is identified as a centurion and called Longinus (making the spear's Latin name "Lancea Longini").
Circumcision of Jesus
The second chapter of the Gospel of Luke records the circumcision of Jesus: 
However, this account is extremely short, particularly compared to Paul the Apostle's much fuller description of his own circumcision in the third chapter of his Epistle to the Philippians. This led theologians Friedrich Schleiermacher and David Strauss to speculate that the author of the Gospel of Luke might have assumed the circumcision to be historical fact, or might have been relating it as recalled by someone else.
