A village close to Aranda de Duero is Quintanarraya, in the province of Burgos and Diocese of Osma, Constantine Miguel Moncalvillo was born on April 12, 1913. He was the son of Agustín Miguel, a day laborer, and Candida Moncalvillo, who already had five children when Constantine was born. He received the Sacrament of Baptism in the parish Church of St. Peter the Apostle on April 16th. In the same parish of St. Peter the Apostle, he received the Sacrament of Confirmation on May 6, 1920, from the Bishop of Osma.
At school he distinguished himself by his behavior and application to his studies. His teacher, Don Deogracias Navas placed him as a role model for the other students and present his notebooks for them to emulate, with its cleanliness and composition. In the parish he was an altar boy. One of his favorite passtimes was to catch crabs with nets. He helped his mother, by carrying water to their home from a source outside of the village. His vocation seemed to be awaken while attending a misión presented by a Claretian and by a cousin who was already living in Alagon.
When he was fourteen years old, he entered the Congregation on August 14, 1927. The Postulancy was in Alagon, so he went with another student from the neighboring town, whose father accompanied them to their destination. In his first two years of Humanities, he seemed to excel and enjoy the seminary. The remaining years of the program would take place in Cervera. During these years, his Prefect was Fr. José Ribe. He completed his studies in Humanities in the summer of 1931 with excellent marks. So the next step was to move on to Vic for the Novitiate. On August 14th, he would begin the year of studies, prayer and tests. With approval, he made his First Profession on August 15, 1932.
Two days later he left for Solsona to study Philosophy. In August 1935, he was in Cervera to begin the studies of Theology. With the Marxist Revolution, he was only able to complete one year of the Theology program.
He was a very bright young man. He devoted himself and seemed to excel in mathematics. He exhibited good characteristics but at times could be somewhat stubborn and possessed an energetic temperament, which he worked at controlling. There was also a part of him which was humble and pietistic.
On July 21, 1936, all of the Claretian Missionaries were expelled from the convent of the former University of Cervera by the Reds. The only option that he had was to join his classmates and take the journey to Solsona. He couldn’t complete the journey because they were not allowed to travel through the town of Tora. At this point, the only option was to take refuge in the Mercedarian Convent of San Ramon. Two days later, he and the other students went to Mas Claret. Here he remained helping on the farm until his death on October 19, 1936. Many young Claretians would be shot as they gathered for a photo. His body was cremated along with the other and buried on the property.
