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).
The Golden Arrow prayer
Sister Mary stated that Jesus told her that the two sins which offend him the most grievously are blasphemy and the profanation of Sunday. He called this prayer the "Golden Arrow", saying that those who would recite it would pierce Him delightfully, and also heal those other wounds inflicted on Him by the malice of sinners. Sr. Mary of St. Peter saw, "streaming from the Sacred Heart of Jesus, delightfully wounded by this 'Golden Arrow,' torrents of graces for the conversion of sinners.
This prayer appears in the book “The Golden Arrow”, the autobiography of Sr. Marie of St Peter. In her book she wrote that in her visions Jesus told her that an act of sacrilege or blasphemy is like a "poisoned arrow", hence the name “Golden Arrow” for this reparatory prayer.
