Saint Domingo Henares – Minh was born on December 19, 1765, in the village of Baena, Diocese of Cordoba, Spain. He was raised in a wealthy family, but his pious mother educated him to love the poor and not let money control him.

At age 16, he asked to enter the Dominican Monastery in Niebla, later moving to the Monastery of the Holy Cross in Granada, and received the Dominican habit on August 30, 1783. After one year as a novice, he asked the novice master to let him go to the Philippines to fulfill his desire to do missionary work in the Far East. Arriving in Manila, he continued his studies in theology and was ordained a priest on September 20, 1789. The Monastery Director wanted to keep the newly ordained priest in Manila, but he still held onto his ambition to spread his wings to distant missionary lands.

The ship docked at Macau harbor. There, Bishop Delgado – Y and two other Dominican missionaries were waiting for him. All four missionaries set foot in Bắc Hà (Northern Vietnam) on October 29, 1790. In just six months, missionary Henares could speak Vietnamese and received the Vietnamese name Minh. He was appointed Director of the Tiên Chu Seminary, also serving as professor of Ascetical Theology and Latin. In 1798, Bishop Delgado – Y appointed him as the Ecclesiastical Superior (Vicar General).

On September 9, 1800, Pope Pius VII appointed him Coadjutor Bishop to succeed Bishop Ignacio Delgado – Y. His episcopal consecration took place on January 9, 1803, in the parish of Phú Nhai.

Bishop Jeronimo Hermosilla – Liêm reported to the Sacred Congregation for the Propagation of the Faith about Bishop Henares – Minh as follows: "He had a pure life, great zeal for saving souls, a longing to die for the faith, ready to go out even in the middle of the night to carry out his pastoral duties; a profoundly holy soul, diligent in prayer and devoted to reading the Church Fathers; a life of poverty in the true spirit of the Gospel, very generous to the unfortunate; one could call him the father of the poor."

While traveling to avoid persecution, Bishop Henares – Minh and Thầy Chiểu (Catechist Chieu) were on a boat from Quất Lâm planning to go out to sea when they encountered a fierce storm. A pagan villager, finding the boat suspicious, invited the two "father and son" to take shelter in his home until the storm passed. But that night, he went and reported them to a high-ranking mandarin to receive a large reward.

Bishop Henares – Minh was arrested, locked in a cage, and escorted to the Nam Định public court on June 11, 1838. The mandarin interrogated him to force the Bishop to reveal the hiding places of other priests, but he remained absolutely silent. The Governor-General Lê Văn Đức ordered the Bishop to step on a cross. The Bishop said: "Would a mandarin have the heart to let a son trample on the body of his own parents? How could I dare step on the image of the Lord, who created heaven and earth, whom all people must revere and adore? Yet you mandarins tempt me to trample on the Holy Cross; even if my bones are crushed and my flesh torn, I cannot commit such an evil act."

Arriving at the execution ground on June 26, 1838, Bishop Henares – Minh stepped out of the cage, called out the Most Holy Name of Jesus three times, and asked for a few moments of silence to pray. He knelt on the ground, his eyes looking to heaven, and inclined his head for the executioner to carry out the sentence. The Bishop was 73 years old, having spent 48 years as a missionary in Vietnam, and 38 years in the ministry of a diocesan bishop.

Saint Bishop Domingo Henares – Minh was beatified on May 27, 1900, and canonized on June 19, 1988.
