Traditionally, sermons at royal weddings are given by senior clergy from the Church of England.
"I'm thrilled that Prince Harry and Meghan Markle have asked Bishop Michael Curry to preach at their wedding," Archbishop of Canterbury Justin Welby, the leader of the Church of England and spiritual head of the Anglican Communion wrote on Twitter. "@PB_Curry is a brilliant pastor, stunning preacher and someone with a great gift for sharing the good news of Jesus Christ."

"They thought he was crazy!" Curry said during the 2012 sermon. "And he was! He is!"
