[1] Anthony à Wood says that he was dismissed the Society for accompanying the Royalist army of the First English Civil War as a military chaplain without the consent of his superiors.
After the Royalist's defeat he studied and became doctor of civil and canon law, probably at the University of Paris.
He was the most prominent opponent of Thomas White and "Blackloism", in other words appeasement of The Protectorate of Oliver Cromwell.
He had a better Latin style than Thomas White alias Blacklow, but had less ecclesiastical learning.
After the Restoration of 1660 he resided with the William Herbert, 1st Marquess of Powis, sometimes in London, and more frequently at Redcastle, in Wales.
