Born in 1579, John Ogilvie belonged to Scottish nobility. Raised a Calvinist, he was educated on the continent. Exposed to the religious controversies of his day and impressed with the faith of the martyrs, he decided to become a Catholic. In 1596, at age seventeen he was received into the Church at Louvain. Later John attended a variety of Catholic educational institutions, and eventually he sought admission into the Jesuits. He was ordained at Paris in 1610 and asked to be sent to Scotland, hoping some Catholic nobles there would aid him given his lineage. Finding none, he went to London, then back to Paris, and finally returned to Scotland. John’s work was quite successful in bring back many people to the Faith. Some time later he was betrayed by one posing as a Catholic. After his arrest he was tortured in prison in an effort to get him to reveal the names of other Catholics, but he refused. After three trials, John was convicted of high treason because he converted Protestants to the Catholic Faith as well as denied the king’s spiritual jurisdiction by upholding the Pope’s spiritual primacy and condemning the oaths of supremacy and allegiance. Sentenced to death, the courageous priest was hanged at Glasgow in 1615 at the age of thirty-six. His feast day is March 10.
