"It’s been remarkable and very surprising," Curry said today on "Good Morning America" of the reaction to his sermon.
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.
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."
"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."
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.'"
