John Warner was born in Warwickshire and died at James II's court-in-exile at St Germains in Paris on 2 November 1692. He was educated for the Roman Catholic priesthood in Spain, and became Professor of Philosophy and Divinity at the Catholic College of Douai. In 1663 he entered the Jesuit order, becoming Professor of Theology at their College in Liège, where English priests received their training. After some years on the English Mission, he was recalled to Liège as rector in 1678. In 1679 he was appointed Principal of his order, which he represented at the twelfth general congregation of the Society of Jesus in Rome in 1682. From 1683 until 1686 he was rector of St Omer's College, then in 1686 James II chose him as his confessor, a post of considerable influence and – given the suspicion in England of Catholics in general and Jesuits in particular – no little danger. He was twice arrested during the Revolution, but managed to escape, rejoining James in France and then accompanying him on the abortive Irish expedition.
