Holy Lance
A Holy Lance is conserved in Vagharshapat (previously known as Echmiadzin), the religious capital of Armenia. It was previously held in the monastery of Geghard. The first source that mentions it is a text "Holy Relics of Our Lord Jesus Christ", in a thirteenth-century Armenian manuscript. According to this text, the spear which pierced Jesus was to have been brought to Armenia by the Apostle Thaddeus. The manuscript does not specify precisely where it was kept, but the Holy Lance gives a description that exactly matches the lance, the monastery gate, since the thirteenth century precisely, the name of Geghardavank (Monastery of the Holy Lance).
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.
