One of the highlights of the Coronation ceremony in Westminster Abbey on 2 June 1953 was the Coronation Oath made by The Queen. Read The Queen's Coronation Oath (from the Order of Service for the Coronation)
The Queen having returned to her Chair, (her Majesty having already on Tuesday, the 4th day of November, 1952, in the presence of the two Houses of Parliament, made and signed the Declaration prescribed by Act of Parliament), the Archbishop standing before her shall administer the Coronation Oath, first asking the Queen,
Madam, is your Majesty willing to take the Oath?
And the Queen answering,
I am willing.
The Archbishop shall minister these questions; and The Queen, having a book in her hands, shall answer each question severally as follows:
Archbishop. Will you solemnly promise and swear to govern the Peoples of the United Kingdom of Great Britain and Northern Ireland, Canada, Australia, New Zealand, the Union of South Africa, Pakistan, and Ceylon, and of your Possessions and the other Territories to any of them belonging or pertaining, according to their respective laws and customs?
Queen. I solemnly promise so to do.
Archbishop. Will you to your power cause Law and Justice, in Mercy, to be executed in all your judgements?
Queen. I will.
Archbishop. Will you to the utmost of your power maintain the Laws of God and the true profession of the Gospel? Will you to the utmost of your power maintain in the United Kingdom the Protestant Reformed Religion established by law? Will you maintain and preserve inviolably the settlement of the Church of England, and the doctrine, worship, discipline, and government thereof, as by law established in England? And will you preserve unto the Bishops and Clergy of England, and to the Churches there committed to their charge, all such rights and privileges, as by law do or shall appertain to them or any of them?
Queen. All this I promise to do.
Then the Queen arising out of her Chair, supported as before, the Sword of State being carried before her, shall go to the Altar, and make her solemn Oath in the sight of all the people to observe the premisses: laying her right hand upon the Holy Gospel in the great Bible (which was before carried in the procession and is now brought from the Altar by the Arch-bishop, and tendered to her as she kneels upon the steps), and saying these words:
The things which I have here before promised, I will perform and keep. So help me God.
Then the Queen shall kiss the Book and sign the Oath.
The Queen having thus taken her Oath shall return again to her Chair, and the Bible shall be delivered to the Dean of Westminster.
