Life
Mamerto de la Ascensión Esquiú was born on 11 May 1826 in Piedra Blanca to Santiago Esquiú and María de las Nieves Medina. His mother chose the name "Mamerto de la Ascensión" in homenage to Saint Mamerto due to his date of birth being the commemoration date for Saint Mamertus while "Ascensión" comprised part of the name because the because Ascension feast fell on his birth.
Esquiú's faith came from his mother and he decided to pursue a path to the priesthood; his mother was a devotee of Francis of Assisi and from age five he himself began to cultivate a devotion and admiration for the Italian saint. He entered the Order of Friars Minor and on 31 May 1836 began his education and his period of novitiate at the Catamarca Franciscan convent in Catamarca. On 14 July 1842 he made his solemn profession into the order and was ordained to the priesthood on 18 October 1848; he celebrated his first Mass on 15 May 1849. He was committed to education being a teacher and professor at the convent for sometime and from 1850 to 1860 taught philosophical studies at a school that Governor Manuel Navarro (1791-1852) had founded.
After the ruthless and devastating Argentine civil war - and during the celebration of the Oath of the Constitution of 9 July 1853 - he preached his famous Sermon of the Constitution where he prayed for the union of all Argentine people. He became noted as a patriot for his preaching and sermons that advocated a united Argentina in accordance with the 1853 constitution. Esquiú lauded the constitution and welcomed it in the name of peace but could not finish the last sentence of his sermon because the audience burst into thunderous applause. President Justo José de Urquiza (1801-70) lauded his comments and ordered the sermon printed and distributed across Argentina.
In 1860 he settled in Paraná as the private aid to the diocese's first bishop Luis Gabriel Segura (1803-62) and remained there until the bishop's death in 1862 before moving to the Franciscan convent at Tarija in Bolivia. He was stationed there until 1867 when the Archbishop of Sucre Pedro José Puch i Solona summoned him; he remained there until 1872 and there published the newspaper dubbed "The Crusader" in response to anti-clericalism. In 1872 - while in Sucre before he left - the President endorsed him as the new Archbishop of Buenos Aires but he refused this and instead moved to Peru and then to Guayaquil in Ecuador to escape further pressure to accept the nomination. Esquiú made a trip to Rome and later to Jerusalem in 1876 and preached on the night of Good Friday to thousands of pilgrims in 1877 before returning to his hometown in late 1878.
He was appointed as the Bishop of Córdoba under Pope Leo XIII on 27 February 1880. Esquiú received his episcopal consecration on 12 December 1880 from the Cardinal Archbishop of Buenos Aires Federico León Aneiros; he later assumed possession of his new episcopal see on 17 January 1881.
Esquiú died at 3:00pm on 10 January 1883 in El Suncho and his remains lie in the Córdoba Cathedral. Before he died he was in La Rioja but returned his diocese on 8 January 1883 weakened; he felt indigestion and was nauseous and could not eat while also being unable to sleep. There is a department in Catamarca Province that is named in his honour. The house where he was born which stands facing the church of San Antonio was declared a National Historic Monument.
