All eyes were on Prince Harry and Meghan Markle on their wedding day Saturday, except for the nearly 14 minutes when the Most Rev. Michael Bruce Curry made history with a soul-stirring sermon at St. George's Chapel that is still generating buzz.
"It’s been remarkable and very surprising," Curry said today on "Good Morning America" of the reaction to his sermon.
The New York-based Curry, who’s the first black leader of the Episcopal Church in the United States, made history again as the first American to preach at a British royal wedding.
Curry said he was "very aware" of the gravitas of the moment.
In addition to Curry's history-making moment, Meghan, now the Duchess of Sussex, also broke ground as an American and biracial daughter of an African-American mother and white father marrying into Britain's royal family.
"The reality is ... the love between those two people, between that loyal couple, was so powerful, not only did we all show up, but it brought all these different worlds together," Curry said. "It brought different nationalities, different ethnicities, different religious traditions, people of all stripes and types, people of different political persuasions.
"Actually for a moment, we were actually together, organized around love," he continued. "Their love was a sign of God’s love and what that love can do in our lives. It brought together our African heritage, our British heritage, our American heritage."
Harry, 33, and Meghan, 36, now known as the Duke and Duchess of Sussex, wed Saturday at St. George's Chapel in front of about 600 guests and a worldwide audience of millions.
Curry said it was Meghan and Harry's decision, in consultation with leaders of the Church of England, to include him in the wedding.
"I didn’t believe it because a member of my staff called and said, ‘They’d like you to preach at the royal wedding,'" Curry recalled. "I said, ‘Get out of here; it’s April Fools. You’ve got to be kidding me.’"
Meghan and Harry's love for each other was "obvious" and could be seen on their faces, according to Curry.
"That love was a reflection of a greater love and that greater love is the love of God," he said. "I think that’s what Jesus has been talking about. That’s what he was trying to teach us. Love God, love your neighbor and you’ll be able to figure out the rest."
Curry spoke in his royal wedding address about the power of love and at one point quoted U.S. civil rights icon Dr. Martin Luther King Jr.
"We must discover the power of love, the redemptive power of love. And when we do that, we will make of this old world a new world," the bishop said Saturday. "Love is the only way. There's power in love. Don't underestimate it. Don't even over-sentimentalize it. There's power, power in love."
King's daughter, Bernice King, immediately recognized her late father's words and tweeted, "#MLK quote at the #RoyalWedding. Your life, teachings and words still matter so much, Daddy. Congrats, Harry and Meghan!"
Church officials and Harry and Meghan were aware of the "basic outline" of his sermon ahead of time, according to Curry.
He said he was able to speak to the couple "very briefly" after the wedding service, describing them as "kind and gracious."
"[It was] more just an opportunity to say hello," Curry said. "[They] just said things like, 'Thank you,' [and] 'It meant a lot.'"
