Openly gay Mo Rocca played a critical role in Pope Francis' Mass at Madison Square Garden in New York City.

Rocca, a former Daily Show correspondent and current CBS Sunday Morning reporter, delivered the first reading at the Mass in Spanish.

Rocca's reading at Francis' first public Mass in the United States was from the Old Testament.

“I am deeply grateful and humbled to have delivered a reading at a Mass celebrated by @Pontifex,” Rocca tweeted.

The response on social media was overwhelmingly positive.

“Seriously, what an amazing statement that the Pope has openly gay Mo Rocca give the first reading. A not-subtle message. Bravo,” messaged Steve Safran (@steviesaf).
