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").
Protevangelium
In Romans 16:20, there is perhaps the clearest reference to the Protevangelium in the New Testament, "And the God of peace shall bruise Satan under your feet shortly. The grace of our Lord Jesus Christ be with you. Amen." Here the seed of the woman is identified as "the God of peace" and yet the Church is identified as the feet that will bruise Satan's head. From the masculine singular Hebrew pronoun in Genesis 3:15, we see that the seed of the woman is a man, and yet in Romans 16:20 he is called the God of peace, which identifies him as the Lord Jesus Christ.
