After he had spent at least five years at Oxford, his parents, who were Catholics, took him from the university and sent him to France, where for a short time he settled in the English College at Reims.
He was sent on 8 March 1585 to the English College, Rome, where he spent six years in studying philosophy and theology, and was ordained priest.
In 1593 the college moved to Douai, where Weston lectured in divinity for about ten years.
He maintained a correspondence with Cardinal Robert Bellarmine, who held similar political views.
[1] Later he was made canon of the collegiate church of St. Mary, Bruges, where, according to Hippolyte-Romain-Joseph Duthillœul, he died in 1635.
