IHS monogram of the Holy Name of Jesus Pendant

In Christianity, the Holy Name of Jesus refers to the theological and devotional use of the name of Jesus. The reverence and affection with which Christians have regarded the Holy Name of Jesus goes back to the earliest days of Christianity.[1] The devotions and venerations also extend to the IHS christogram (a monogram of the Holy Name), derived from the Greek word IHSOUS (ΙΗΣΟΥΣ) for Jesus, or referring to Iesus Hominum Salvator, Jesus saviour of mankind, representing the Holy Name.[2][3][4] Devotions to the Holy Name of Jesus exist both in Eastern and Western Christianity.[5] The feast day is celebrated either as the Feast of the Holy Name of Jesus or as that of Circumcision of Jesus, in various Christian churches. The Gospel of Matthew provides a specific meaning and intention for the name Jesus (as the one who "saves his people from sin") and indicates that it was selected by Heavenly guidance. For centuries, Christians have invoked the Holy Name, and have believed that there is intrinsic power in the name of Jesus.
