Last year, there were 762 American baby boys given the name Messiah, putting it right between old standbys Scott and Jay for popularity, according to the Social Security Administration database. As currently formulated, the magistrate’s reasoning would be a problem not only for all of them, but also for all the Americans, primarily of Hispanic ancestry, who have named their sons Jesus. There were 3,758 Americans given the name Jesus last year, putting it way ahead of Messiah.

Now, one could argue that Jesus does not necessarily refer to Jesus Christ, the one believed to be the Messiah (“Christ” is one Greek-derived translation for “messiah”). But surely that’s whom most parents have in mind. Jesús finds particular favor among Roman Catholics in Mexico and Central America, where so many recent immigrants come from. It is less popular in Spain.

“My impression,” said Ilan Stavans, who teaches Spanish literature at Amherst College, “is that there is an identification in Latin America with characters of the Passion that you don’t find in other parts of the world, including Spain.”

Yet as Mr. Stavans points out, the tradition of religious naming in Latin America goes beyond those involved in the events, known as the Passion, leading up to Jesus’ crucifixion. Many Latinos are happy to name their children versions of the word “God.”

“Adonai is also a common name among Latinos, especially Mexicans,” Mr. Stavans said. “And so is Elohim.” Those are both Hebrew versions of the word for the deity. “But neither of them,” he added, “matches the ubiquity of Jesus, closely followed by Maria, Jose and Guadalupe.”

Hebrew-derived names are particularly popular among Latinos who have become Pentecostal Protestants, according to Arlene Sánchez-Walsh, a historian at Azusa Pacific University, in Azusa, Calif. As Pentecostalism has spread in Latin America, new adherents have a “desire to connect to Old Testament prophets, Jewish dietary laws and sometimes Sabbath keeping,” Ms. Sánchez-Walsh said. It “gives Latino Pentecostals a stake in their religious heritage as non-Catholics — which is what a lot of this is about.”
