One of the customs we maintain at our parish is that of bowing one's head at the name of our Lord. It's nothing exaggerated, but just a sign of respect at the sound of the Name of our salvation. There are so many acts of courtesy and respect which have been lost in our everyday living, but there are things such as this that I refuse to put aside. It may seem a little thing, but I believe it is important that we pause and acknowledge the wonder of what God in Christ has done, and is doing. The very idea that the Creator of all things has such love for us that He has put on human flesh in the womb of the chosen maiden, and has taken for Himself the particular name of Jesus, and gives Himself to us daily in the Holy Sacrifice of the Mass -- that should make us want to bow our heads in wonder and praise. "For there is no other name under heaven given to men, whereby we must be saved."
Eternal Father, who didst give to thine incarnate Son the holy name of Jesus to be the sign of our salvation: Plant in every heart, we beseech thee, the love of him who is the Saviour of the world, even our Lord Jesus Christ; who liveth and reigneth with thee and the Holy Spirit, one God, in glory everlasting. Amen.
