Below is St. Paul's teaching on the sacredness of the Holy Name of Jesus:
 For let this mind be in you, which was also in Christ Jesus:
 Who being in the form of God, thought it not robbery to be equal with God:  But emptied himself, taking the form of a servant, being made in the likeness of men, and in habit found as a man.  He humbled himself, becoming obedient unto death, even to the death of the cross.  For which cause God also hath exalted him, and hath given him a name which is above all names:  That in the name of Jesus every knee should bow, of those that are in heaven, on earth, and under the earth:
 Emptied himself: exinanivit, made himself as of no account.
 And that every tongue should confess that the Lord Jesus Christ is in the glory of God the Father.
Jesus Christ, the second person of the Blessed Trinity, is to revered in the Most Blessed Sacrament, and when announced audibly, even in casual conversation. It is customary for Catholics to strike their breasts when the Holy Name of Jesus is announced, whether it's in Church or not. The Sign of the Cross is supposed to be made by a Catholic when passing by a [traditional] Catholic Church. (If you are the driver, you obviously can't sign without getting into an accident!) Every time we pass by the Blessed Sacrament, we genuflect on our right knees. When Jesus is exposed in the monstrance, then we kneel on both knees. (Likewise, when the bishop passes by, we genuflect on the left knee.)
Sadly, in today's post-concilliar period, Our Lord has been removed from the high altar and placed in a side chapel in all parish churches. There is no such thing as the high altar in many places, and they have been replaced with a "presidential chair", just like a masonic lodge. But worse, many parishes have closed, seminaries closed, convents empty, professed religious abandoning their vows, Catholic school have closed with the remaining ones Catholic in name only, etc. All this is because of the lack of respect for the Holy Name.
