[1] Mocket held the rectories of Newington, Oxfordshire, and of West Tarring, Sussex, from 1614, and of Monks Risborough, Buckinghamshire, from 1615 till his death.
The authorship of a tract, upholding the obligation of the oath of allegiance, and entitled God and the King (in Latin Deus et rex), has been ascribed to Mocket; Glenn Burgess comments in the Oxford Dictionary of National Biography on the lack of firm evidence that he was the author.
This command was enjoined by the privy council of Scotland in June 1616, and by the general assembly at Aberdeen in August 1616, and the work sold widely.
[3] The content is a mixture of history (an account of Catholic intrigues against James and Elizabeth I), and religious generalities, to justify the requirement of an oath of allegiance.
It comprised: To these he added a work of his own entitled Doctrina et Politia Ecclesiæ Anglicanæ, which was a general view of ecclesiastical jurisdiction in the English church, mainly prepared for the information of foreigners.
Peter Heylyn in his Cyprianus Anglicus, while criticising Mocket's ignorance and Calvinism, was of opinion that the real offence was the omission of the first clause in the Latin text of the twentieth of the Thirty-Nine Articles, which runs: ‘The Church hath power to decree rites or ceremonies, and authority in controversies of faith.’ It was also said that Mocket's extracts from the homilies were made so as to support the views of Abbot, and that as a translator he had acted as a commentator; while James Montagu, bishop of Winchester, resented the order in which the bishoprics were enumerated.
[7] Clegg puts the incident in the context of the divisive church politics of the Netherlands—–the Calvinist-Arminian debate ahead of the Synod of Dort of 1618–9—and the tensions among bishops at court (agreeing in part with the direction of the comments in Fuller and Heylyn).
On the assumption that Doctrina et Politia was directed at overseas Protestants, the rendering of Article 20 had the misfortune to contradict the King's policy for handling the Dutch Remonstrants, by weakening the case for a conciliar solution to the theological issues under dispute.
Late in 1617 Sir Dudley Carleton reported to Thomas Lake the circulation of a Dutch book Weeg-schaal by Jacob Taurinus, contrasting King James's actions at the Hampton Court Conference to his advocacy of a council in the Netherlands.
