In 1609 he succeeded Lancelot Andrewes in the prebend of St. Pancras in St. Paul's, which made him rector and patron, as well as vicar, of Chigwell.
Fenton was one of the Second Westminster Company of translators of the King James Bible, dealing with the Epistles of the New Testament.
In 1652 there appeared a tract by Robert Filmer[2] The author states in his preface that George Downame, Fenton and Andrewes are the noted opponents of usury, in England, but (he continues) 'I have made choice of Dr. Fenton's treatise to examine because it is latest, and I find little of any moment but is in him.'
Like the English treatise Of Usurie this Latin document consists of the resolution of three disputed questions on the subject of the work.
Fenton was a popular preacher of the day; one of his sermons, 'Of Simonie and Sacriledge,' was published in 1604, from which it appears that he was at that date chaplain to Sir Thomas Egerton, the lord chancellor.
Utie prefixes a dedication of his own to Sir Francis Bacon, in which he calls the treatise 'the Posthumus [image] of Doctor Fenton', but says that it lacked final revision.
