Bishop Michael Curry was without a doubt one of the standout moments of Prince Harry and Meghan Markle's grandiose royal wedding. 

Curry's bold sermon Saturday set social media ablaze for its passionate words and unapologetic blackness, which likely left the royal family a little shook, too.  

Invoking the words of civil rights icon, Dr. Martin Luther King Jr., Curry preached in St. George’s Chapel at Windsor Castle about the importance of love in all things that we do. 

“Set me as a seal upon your heart, as a seal upon your arm; for love is strong as death, passion fierce as the grave. Its flashes are flashes of fire, a raging flame. Many waters cannot quench love, neither can floods drown it," he said to the royal wedding attendees. “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.” 

The Chicago native, who rose up the ranks as a preacher to become the leader of the Episcopal Church in the United States, took the royals, Hollywood celebrities, and politicians off guard when he went on to mention slavery in his sermon as well. 

“I’m talking about some power. Real power,” he continued. “Power to change the world. If you don’t believe me, well, there were some old slaves in America’s antebellum South who explained the dynamic power of love and why it has the power to transform. They explained it this way: They sang a spiritual, even in the midst of their captivity. It’s one that says there is a balm in Gilead, a healing balm — something that can make things right. There is a balm in Gilead to make the wounded whole.”

There was definitely no avoiding the looks on the royal wedding guests' faces upon this unexpected portion of Curry's speech.

The English played an instrumental role in the slave trade. The wealth that the British royal family enjoys today likely comes from the revenue made by enslaved West Africans toiling away in the New World for free. Curry's sermon reminded the chapel that those slaves' faith — their love for God — kept them alive.

Twitter took notice of how important Curry's words were at this moment, too. 

After his words rang throughout the chapel, the Kingdom Choir full of black Brits sang a rendition of Ben E. King's "Stand By Me."
