This three-stamp commemorative issue from Vatican City (1973) honors St. Nerses Shnorhali (1102–1173), the revered Armenian Catholicos, theologian, and poet known for promoting unity among Christian churches. The set features three symbolic designs: an ornate Armenian cross (L.90), the historic Santa Hripsime Church (L.25), and a portrait of St. Nerses himself (L.180). Printed by the Vatican’s I.P.S. Roma press, the stamps showcase intricate line engraving and traditional Armenian Christian motifs. The issue reflects the Vatican’s recognition of Armenian spiritual heritage and ecumenical dialogue. A meaningful addition for collectors of religious, Vatican, and Armenian history themed philately.
