In 1179 he attended the Council of Hromkla, in which the terms of the union were discussed. His address at this council is considered a masterpiece of eloquence and style.
Nerses was well versed in sacred and profane sciences and had an excellent knowledge of Greek, Latin, Syriac, and probably Coptic. Nerses became a zealous advocate of the union of the Greek and Armenian Churches. The union was decided upon but never consummated owing to the death of Emperor Manuel Comnenus in 1180.
Manuel"s successors abandoned the negotiations and persecuted the Armenians, who were dissatisfied with the Byzantines and turned to the Latins.
Leo II, Prince of Cilicia, desirous to secure for himself the title of King of Armenia, sought the support of Pope Celestine III and of Emperor Henry VI. The pope received his request favourably, but made the granting of it dependent upon the union of Cilicia to the Church of Rome. He sent Conrad, Archbishop of Mainz, to Tarsus, and the terms of union having been signed by Leo and twelve of the bishops, among whom was Nerses, Leo was crowned King of Armenia, 6 January 1198.
Nerses died six months afterwards, on 17 July.
