# Act of Supremacy 1558

The Act of Supremacy 1558 (1 Eliz. 1. c. 1), sometimes referred to as the Act of Supremacy 1559, is an act of the Parliament of England, which replaced the original Act of Supremacy 1534, and passed under the auspices of Elizabeth I. The 1534 act was issued by Elizabeth's father, Henry VIII, which arrogated ecclesiastical authority to the monarchy, but which had been repealed by Mary I. Along with the Act of Uniformity 1558, the act made up what is generally referred to as the Elizabethan Religious Settlement.
The act remained in place until the 19th century, when some sections began to be repealed. By 1969, all provisions, bar section 8 (which still remains in force), had been repealed by various acts, with the whole act repealed in Northern Ireland between 1950 and 1953.

## The act

The act revived ten Acts which Mary I had revoked, significantly clarified and narrowed the definition of what constituted heresy, and confirmed Elizabeth as Supreme Governor of the Church of England. Compared to Henry VIII's title of "Supreme Head", Supreme Governor avoided the blasphemous implication that Elizabeth was superior in rank to Jesus, whom the Epistle to the Ephesians identifies as head of the church.
The act also made it a crime to assert the authority of any foreign prince, prelate, or other authority, and was aimed at abolishing the authority of the Pope in England. A third offence was high treason, punishable by death.

### The oath

The Oath of Supremacy, imposed by the act, provided for any person taking public or church office in England to swear allegiance to the monarch as Supreme Governor of the Church of England. Failure to so swear was a crime, although it did not become treason until 1562, when the Supremacy of the Crown Act 1562 (5 Eliz. 1. c. 1) made refusal to take the oath a treasonable offence. The oath was later extended to include Members of Parliament and those studying at universities: all but one of the bishops lost their posts and a hundred fellows of Oxford colleges were deprived, as many dignitaries resigned rather than take the oath. The bishops who were removed from the ecclesiastical bench were replaced by appointees who would agree to the reforms.
Text of the oath as published in 1559:
   I, A. B., do utterly testify and declare in my conscience that the Queen's Highness is the only supreme governor of this realm, and of all other her Highness's dominions and countries, as well in all spiritual or ecclesiastical things or causes, as temporal, and that no foreign prince, person, prelate, state or potentate hath or ought to have any jurisdiction, power, superiority, pre-eminence or authority ecclesiastical or spiritual within this realm; and therefore I do utterly renounce and forsake all foreign jurisdictions, powers, superiorities and authorities, and do promise that from henceforth I shall bear faith and true allegiance to the Queen's Highness, her heirs and lawful successors, and to my power shall assist and defend all jurisdictions, pre-eminences, privileges and authorities granted or belonging to the Queen's Highness, her heirs or successors, or united or annexed to the imperial crown of this realm. So help me God, and by the contents of this Book.
This had a specific impact on English Roman Catholics since it expressly indicates that they must forswear allegiance to Roman Catholicism, inasmuch as the Church of Rome was directly a foreign jurisdiction, power, superiority and authority. However, during the early years of her reign Elizabeth practised religious clemency and tolerance, which was an attempt to harmonise the state of affairs between the Roman Catholics and the Church of England. This was necessary for Elizabeth to establish her power fully, hold off threats of invasion from France and Spain, and to counter accusations of illegitimacy that plagued her early years. In the last twenty years of her reign, as the Pope issued official encouragement to topple, and even kill, Elizabeth, as Jesuits infiltrated England, and as the threat of Spanish invasion loomed, Catholics became targets for oppression. Later, Roman Catholic power within England waned (because Roman Catholics were forbidden to take public office and were slowly deprived of their lands and fortunes) but their influence grew until they attempted the Gunpowder Plot in 1605 – whereupon they were oppressed for nearly 200 years.

### Text in force today

Section 8 still remains in force in Great Britain, and reads as follows:
   AND That suche Jurisdictions Privileges Superiorities and Preheminences Spirituall and Ecclesiasticall, as by any Spirituall or Ecclesiasticall Power or Aucthorite hathe heretofore bene or may lawfully be exercised or used for the Visitacion of the Ecclesiasticall State and Persons, and for Reformacion Order and Correccion of the same and of all maner of Errours Heresies Scismes Abuses Offences Contemptes and Enormities, shall for ever by aucthorite of this present Parliament be united and annexed to the Imperiall Crowne of this Realme: ...
The words at the end were repealed in 1641 by the Abolition of High Commission Court Act 1640 (16 Cha. 1. c. 11).
