Nerses IV the Gracious

Nerses IV the Gracious (; also Nerses Shnorhali, Nerses of Kla or Saint Nerses the Graceful; 1102 – 13 August 1173) was Catholicos of Armenia from 1166 to 1173. During his time as a bishop and, later, as Catholicos of the Armenian Church, Nerses worked to bring about reconciliation with the Eastern Orthodox Church and convened a council with emissaries selected by the Byzantine emperor himself to discuss how they might be able to reunite the two churches. The terms the emperor offered were, however, unacceptable to both Nerses and the Armenian Church, and the negotiations collapsed. Nerses is remembered as a theologian, poet, writer and hymn composer. He has been called "the Fénelon of Armenia" for his efforts to draw the Armenian church out of isolation, and has been recognized as a saint by the Catholic Church, which holds his feast on August 13, and by the Armenian Apostolic Church, who celebrate him in mid October on the Saturday of the Fourth Week of the Holy Cross.

Nerses was born in approximately 1100 into the noble Pahlavuni family. Nerses was the name he adopted upon ordination as a priest; his birth name is unknown. According to some sources, he was born in the castle of Dzovk in the province of Tluk in Cilicia, However, other sources claim that Nerses was born in his family's fortress, also called Dzovk, in the historical province of Sophene in Armenia, Nerses moved to Dzovk in Cilicia, named after their original home, with his brother, the future Catholicos Gregory III, after the death of their father in 1111. (a cousin of Nerses) placed them under the tutelage of the monk Stepanos Manouk, a highly regarded scholar and theologian. Nerses' epithet Shnorhali, which may be translated as 'graceful' appears to have been an honorary title given to the graduates of Karmir Vank, although others have suggested that he received this title for the grace of his person, speech and written works

In 1165, hostilities broke out between Thoros II, Prince of Armenia and Oshin of Lampron, the two strongest Armenian princes of Cilicia. and one prayer in particular, Havatov Khostovanim (I Confess with Faith), is currently available in 36 languages. In James R. Russell's view, Nerses' poetry emphasizes "the imagery of fire and light in a manner at once redolent of Hesychasm and consonant with the Zoroastrian substrate of Armenian Christian culture." One work of Nerses which has since been lost is a commentary on the Book of Genesis. In that work, he related the story he received from some Armenian monks who came to visit him during his time as Catholicos to tell him of how they were able to see the Garden of Eden from a distance. In one painting of the scene, the vegetation of the Garden appear as colored gemstones. Unfortunately, the angel with a sword appointed to guard the garden would not allow the monks to take one of the blossoms with them.

In the Roman Catholic Church he is venerated as St. Nerses Glaietsi, Nerses Clayatsi alongside his nephew, St. Nerses of Lambron, both being considered champions of Church unity.
