The American Bishop who became the star of the Royal Wedding with his powerful sermon says he had no idea how much of a hit it would be and that he initially thought his invitation was an April Fool’s joke.

Reverend Michael Curry, whose 14-minute speech became an internet sensation but raised eyebrows among some members of the royal family, has since returned to the US following Saturday’s grand event in Windsor.

Speaking of how he thought his sermon went, which was the most-tweeted about moment of the royal wedding, he said: ‘I have to admit I had no idea… I really didn’t.

‘When I sat down from the sermon I remember thinking to myself, I hope that was OK.’

At the service in St George’s Chapel, the bishop opened his emotional 14-minute speech entitled The Power of Love with the words of civil rights leader Martin Luther King Jr.

The bishop, the first African-American presiding bishop and primate of the Episcopal Church, said: ‘We must discover the power of love, the redemptive power of love. And when we do that, we will be able to make of this old world a new world. Love is the only way.’
