The traditional Roman calendar associated this day with the Holy Name of Jesus -- that is, unless on a Sunday between the first and sixth of the month, don't ask me why. Historically, the observance of this feast has been all over the place until nearly one hundred years ago. The circumcision of a newborn male under Jewish law must take place eight days after the child's birth, at which time he is given his name. Small wonder, then, that the Gospel readings for both feasts in the traditional Roman calendar are the same. Some Western traditions, such as Anglican and Lutheran, celebrate both on the first of January. This year, for reasons mentioned above, the feast occurs today on the traditional calendar -- but tomorrow on the reformed calendar. Again, don't ask me why.
Once I heard a comedian pose this important theological question: “If Jesus was Jewish, why did He have an Hispanic name?” That occasion aside, it gives us occasion to consider that the name "Jesus" was not an uncommon one in His day. Brian Palmer writes for Slate:
Many people shared the name. Christ's given name, commonly Romanized as Yeshua, was quite common in first-century Galilee. (Jesus comes from the transliteration of Yeshua into Greek and then English.) Archaeologists have unearthed the tombs of 71 Yeshuas from the period of Jesus' death. The name also appears 30 times in the Old Testament in reference to four separate characters -- including a descendant of Aaron who helped to distribute offerings of grain (2 Chronicles 31:15) and a man who accompanied former captives of Nebuchadnezzar back to Jerusalem (Ezra 2:2) ...
How would Christ have been addressed by those around him? Well, certainly not as "Mister Christ." In fact, "Christ" was not a name, but a title, from the Greek Khristós or "anointed one." The Hebrew word was Moshiach or "Messiah." He would have been known by His given name, and the name of His father -- Yeshua bar Yehosef or "Jesus Son of Joseph." In later centuries (or in present-day Iceland), He might have been addressed as "Jesus Josephson," but that's just a hunch. We know that He eventually left Nazareth of Galilee, the town of His childhood, for other parts of that country, as well as Samaria and Judea. In those places, He would have been just as likely addressed as Yeshua Nasraya or "Jesus of Nazareth." We know from Scripture that such was the inscription on the Cross, which gave both His name and His offense, in three languages: "Jesus of Nazareth, King of the Jews" (actually, "Iesus Nazarenus Rex Iudaeorum" in Latin, "Ihsoûs ó Nazoraîos ó Basileùs tôn ’Ioudaìov" in Greek, and "Yeshua HaNazarei v Melech HaYehudim" in Hebrew). After all, a guy from a hick town like that would have been rather conspicuous in a high-falutin' place like Jerusalem, especially outside of the High Holydays.
Or so I've read.
Devotion to the Holy Name has also been the inspiration for the National Association of the Holy Name Society. HNS chapters have been the basis for men's clubs in Catholic parishes for generations.
