The month of January is for the devotion and veneration of the Holy Name of Jesus. Represented by the monogram IHS. For centuries, Christians have invoked the Holy Name, and have believed that there is intrinsic power in the name of Jesus. The reverence with which Christians have regarded the Holy Name of Jesus goes back to the earliest days of Christianity, as shown in Acts 4:10 and Philippians 2:10.
Christ's name is chosen in heaven, and the Angel Gabriel announces it when he informs the Blessed Virgin of the incarnation: "Behold thou shalt conceive in thy womb and shalt bring forth a son, and thou shalt call his name Jesus". It is a name that has marvelous implications, for it means "savior." The very name bespeaks the magnitude of His mission, His infinite love, a love that will cause Him to offer Himself up for us.
This feast is celebrated on the second Sunday after Epiphany. Our Lord Himself solemnly promises that whatever we ask the Father in His Name we shall receive. God never fails to keep His word. This feast originated towards the end of the fifteenth century, and was instituted by the private authority of some bishops in Germany, Scotland, England, Spain, and Belgium. The Office and the Mass composed by Bernardine dei Busti (d. 1500) were approved by Sixtus IV. The feast was officially granted to the Franciscans 25 February, 1530, and spread over a great part of the Church. — Excepted from the Catholic Encyclopedia
"We give honor to the Name of Jesus, not because we believe that there is any intrinsic power hidden in the letters composing it, but because the Name of Jesus reminds us of all the blessings we receive through our Holy Redeemer. So the word of St. Paul is fulfilled: "That in the name of Jesus every knee should bow, of those that are in heaven, on earth, and under the earth" (Philippians 2:10).
A special lover of the Holy Name was St. Bernard, who speaks of it in most glowing terms in many of his sermons. But the greatest promoters of this devotion were St. Bernardine of Siena and St. John Capistran. They carried with them on their missions in the turbulent cities of Italy a copy of the monogram of the Holy Name, surrounded by rays, painted on a wooden tablet, wherewith they blessed the sick and wrought great miracles. At the close of their sermons they exhibited this emblem to the faithful and asked them to prostrate themselves, to adore the Redeemer of mankind. They recommended their hearers to have the monogram of Jesus placed over the gates of their cities and above the doors of their dwelling (cf. Seeberger, "Key to the Spiritual Treasures", 1897, 102).
Because the manner in which St. Bernardine preached this devotion was new, he was accused by his enemies, and brought before the tribunal of Pope Martin V. But St. John Capistran defended his master so successfully that the pope not only permitted the worship of the Holy Name, but also assisted at a procession in which the holy monogram was carried. The tablet used by St. Bernardine is venerated at Santa Maria in Ara Coeli at Rome.
The emblem or monogram representing the Holy Name of Jesus consists of
the three letters: IHS. In the Middle Ages the Name of Jesus was written: IHESUS; the monogram contains the first and last letter of the Holy Name. It is first found on a gold coin of the eight century: DN IHS CHS REX REGNANTIUM (The Lord Jesus Christ, King of Kings). Some erroneously say that the three letters are the initials of: "Jesus Hominum Salvator" (Jesus Saviour of Men).
The Jesuits made this monogram the emblem of their Society, adding a cross over the H and three nails under it. Consequently a new explanation of the emblem was invented, pretending that the nails originally were a "V", and that the monogram stands for "In Hoc Signo Vinces" (In This Sign you shall Conquer), the words which, according to a legendary account, Constantine saw in the heavens under the Sign of the Cross before the battle at the Milvian bridge (312)."

Jesus is our all. In His name we may pray to the Father with assurance of being heard. In His name the Church administers all her sacraments. In His name she offers all her prayers and blesses homes, the fields, and the sick. In the name of Jesus she casts out evil spirits, and at the hour of our death bids us, "Go forth, Christian soul." She assures us that whoever shall call upon this name will be saved. When our soul has departed this life to seek its eternal home, the Church asks in the name of Jesus, "Eternal rest give unto him, O Lord." — Benedict Baur, O.S.B.
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.
