A fellow American who shares Meghan Markle's African-American heritage, Curry is also a moderniser who has publicly resisted the populist and nationalist agenda of Donald Trump.
According to Kensington Palace, the duo have asked The Most Reverend Michael Bruce Curry, the 27 Presiding Bishop and Primate of The Episcopal Church, to attend their wedding and give an address.
Curry does not know the couple personally, said Neva Rae Fox, a spokesperson for the Episcopal Church, but he will meet them before the ceremony.
The Most Reverend Michael Bruce Curry will travel from his home in Chicago, Illinois to attend the service next Saturday. "The bishop is honored and thrilled to be participating".
She is understood to have chosen to join the Church of England out of respect for the role Harry's grandmother Queen Elizabeth II has as supreme governor of the Anglican Communion's mother church.
Curry is the son of the late-Rev.
This story has been corrected to show that Curry has served as a bishop in North Carolina, not Chicago. He has often drawn parallels between the black and LGBT civil rights movements. The archbishop of Canterbury, Justin Welby, said at the time that such a decision "will cause distress for some and have ramifications for the Anglican Communion as a whole, as well as for its ecumenical and interfaith resolutions".
But what's particularly of interest is that Curry often speaks on marriage equality. "And this conjures that up again, and brings pain".
The couple will officially tie the knot at noon in the United Kingdom, meaning if you want to catch the royal wedding live, you're going to need to wake up bright and early for a 7:00 am EST viewing party (unless you live on the east coast, which means you'll need to have your TV on at 4 a.m. PST!) The archbishop, the reverend and the US bishop will lead the couple in an hour-long wedding ceremony that will take place at St. George's Chapel at Windsor Castle. " @PB_Curry is still a brilliant pastor, magnificent preacher and somebody else using a wonderful gift for sharing that the fantastic news of Jesus Christ".
