The Queen and the Duke of Edinburgh were this week celebrating their diamond wedding anniversary.
Dr Rowan Williams, the Archbishop of Canterbury, praised the couple's 60 years of marriage saying it was a faithful and creative one that had been maintained in the "full light of publicity."
Some 2,000 people at Westminster Abbey were in attendance to hear the Archbishop's sermon, reports the Times.
Princess Elizabeth married Lieutenant Philip Mountbatten on Thursday 20th 1947 and she is the first British sovereign to celebrate a diamond wedding anniversary.
Dr Rowan said: "Every marriage is a public event, but some couples have to live more than others in the full light of publicity.
"We are probably more aware than ever these days of the pressures this brings. But it also means that we can give special thanks for the very public character of the witness and the sign offered to us by this marriage, and what it has meant to nation and Commonwealth over the decades.
"And part of what it has meant has had to do precisely with the sense of unqualified commitment that has been so characteristic of every aspect of this reign: the faithful and creative personal partnership at the centre of everything else has been a sign of creative faithfulness to a task, a vocation, the creative faithfulness that secures the trust, love and prayerful support of millions."
