Saint Dominic Henares lived between 1764 and 1838 and was born in Spain to a poor family. In 1790 he was ordained a priest in the Dominican Order. He was sent as a missionary to the Far East ten years after and went to Mexico the Philippines and then to North Vietnam. In 1804 he became a Bishop of Phunhay, Vietnam. However, the Vietnamese emperor prohibited Catholicism in 1841 and persecuted the Church where villages were sent to exile and priests tortured and then killed. People who assisted in catching priests were also rewarded. On June 25, 1848, Bishop Henares was arrested and beheaded in Nam Dinh. The soldiers and villagers who helped in his arrest received great compensation. The estimated amount of Catholic martyred in Vietnam between 15th and 20th centuries is between 130 000 to 300 000, which Saint Dominic Henares was one. Pope St. John Paul II canonised them in 1988. The collective memorial for 117 of the Vietnamese Martyrs is on November 24.
