The centenary anniversary has been a time to recognize the healing and progress that has been made, he added.
"(T)he Armenians made the whole world see what it is to overcome an injustice. They gave the possibility to the world to understand what a genocide is, what the denial of a genocide is. Let's not forget that the term 'genocide' was created above all based on the study of the Armenian genocide."
The ambassador also said the year has been a time to recognize everyone who has supported the Armenians and raised awareness of the genocide, including Pope Francis, who has recognized the genocide as religiously motivated.
During Mass on Divine Mercy Sunday on April 12, 2015, Pope Francis referred to the mass killing of Armenians by the Ottoman Turks starting in 1915, as a genocide, a term used in a common declaration signed by both Saint John Paul II and Supreme Armenian Patriarch Karekin II in 2001. That day, Francis offered the Mass for faithful of the Armenian rite in commemoration of the centenary of the "Metz Yeghern," or Armenian "martyrdom," which is historically held to have started April 24, 1915.
"We are also very grateful, very grateful to the people from the smallest to the greatest, from Pope Francis, who did something historic celebrating Mass for the Armenian martyrs April 12...calling things as they are, creating another term, 'ecumenism of blood.' An ecumenism founded on blood, because the Armenians were exterminated also because they were Christians."
"Certainly Pope Francis made one of the most fundamental steps in celebrating this Mass in St. Peter's inviting the hierarchy of the Apostolic Armenian Church and of the Armenian Catholic Church, and proclaiming St. Gregory of Narek as a doctor of the Universal Church," he added.
