Faithful cheer as Pope Francis arrives to celebrate Mass at Christ the Redeemer square in Santa Cruz, Bolivia, Thursday, July 9, 2015. After the Mass, Francis' main event of the day is a keynote speech to a summit of grass-roots groups whose advocacy for the poor and marginalized has been championed by history's first Latin American pope.

SANTA CRUZ, Bolivia — Burger King has long been providing quick meals. Pope Francis has now used for a quick change.

With hundreds of thousands of Catholic faithful waiting, Pope Francis needed a place to don his vestments to celebrate Mass at the Christ the Redeemer square in Santa Cruz. He had just spent more than 30 minutes in his popemobile, waving to thousands lined up on the streets as he arriving to the square for service.

Enter the restaurant known for Whoppers and fries.

The famously unpretentious pope used the fast food joint, which was closed for the morning for the papal visit, before walking to the nearby altar and beginning the Mass.

Alfredo Troche, manager of the Burger King, said the papal entourage had approached the restaurant and "asked for help because this was an appropriate place and we had closed" to customers.

Minutes later, during his homily, Francis blasted consumerism. He said that by materialistic logic, everything becomes an object that can be consumed and negotiated.

The company wasted no time in letting the world of the papal visit. Even before Mass had ended, the restaurant put a post on Facebook thanking the pope "for choosing the BK restaurant as your sacristy."

It also included an advertisement-like image showing the pope beneath a Burger King logo and the words: "There are visits that don't just bring joy to your spirit, but also feed it."
