With Pope Leo XIV assuming his post, college football coaching legend Lou Holtz shared an important message for every Catholic around the globe. 

Holtz said he has been "Catholic all my life," serving as an altar boy as well. He urged people in the United States and around the world to be gracious to Pope Leo as he begins his leadership of the church. 

"I’m an old man, I’ve been Catholic all my life. I was taught about how the pope would be selected. The white smoke, the black smoke, et cetera," Holtz began his message. "But you never know about the pope, because he isn’t infallible. He’s infallible when everything comes to religious decisions, and we’re taught to respect him and pray for him and listen to him.

"I hope this pope will be a very, very good one, but I do know this: He is our pope. We must defend him, we must encourage him, we must pray for him, and we must help him."

Holtz continued by arguing "too many people don’t give enough to the church today," and perhaps that is due to some not believing in past papal decisions. 

"The church has financial obligations like anything else. So, whether you like the pope or not, is irrelevant. He’s our pope. You must respect him, pray for him, and care about him at the same time, accept the decisions he makes.

MEDIA POSITIONS POPE LEO XIV AS POTENTIAL 'COUNTERWEIGHT' TO TRUMP

"It’s important for us to support the pope regardless of who he is, whether we like him or not. Pray for him. Pray for the decisions that they make. I’ve been blessed to know two popes, have visits with them. Let’s make sure that we pray for the pope, follow his blessings and teachings because they’ve led us the correct way for so many years. 

"Good luck to you, and I promise you, I will pray for the pope because I know the pope’s also going to pray for me and pray for the choices he makes in the best interest of this country."

Since Cardinal Robert Prevost was elected as the first American pope last week, many wanted to learn about the new leader of the church. 

Louis Prevost, his conservative brother, pushed back on accusations that Pope Leo would be a "woke" successor to the late Pope Francis. 

"He wasn’t, like, super political," Prevost told Piers Morgan on "Uncensored." "He’s not left, he’s not right, he looks at the whole scene, takes information from both sides, and somehow finds a way to go down the middle and not ruffle too many feathers."

Prevost did, however, address Pope Leo’s previous criticism of President Donald Trump’s methods amid the migrant crisis. 

"He may take offense with the method in which they’re moving people out and comment on that," but nonetheless, "you still have to follow the rules of the law."

Holtz is a staunch Trump supporter, posting similar videos of his praise for the 47th president. 

Holtz coached for 33 years in college with six different programs, most notably Notre Dame, where he went 100-30 over his 11 years with the Fighting Irish.

Americans have mixed feelings about President Donald Trump's administration accepting a $400 million gift from Qatar, with some telling Fox News Digital that it was a "bad idea" to accept a luxury jet from a foreign government.

"I think that's a bad idea. There's no such thing as a free gift and there's some sort of strings or attachments or something else that's probably going to go along with that and that's just concerning," Karisa from Knoxville, Tennessee, told Fox News Digital.

Trump has received backlash for planning to accept the jumbo Boeing 747-8 jet from the Qatari royal family on behalf of the U.S. government since news of the gift broke on Sunday. The luxury jet, which was offered to the United States because of delays in Boeing's production of the new Air Force One fleet, will serve as a temporary method of transportation so that the current presidential plane doesn't have to be flown.

"I think it's a good idea for the country to accept that. We've accepted other gifts from other countries, including the Statue of Liberty, so I can't see a problem with that," Carrie of Kentucky, who was visiting Knoxville, said.

Another person from Detroit, Michigan, said, "That's kind of crazy."

The Boeing 747 offered to the United States by Qatar will be given to the Department of Defense, Trump said Tuesday, responding to questions about the legality of accepting a gift from a foreign power. 

The White House has pushed back against criticism of the president, saying any gift from a foreign power is always accepted in full compliance with all laws.

"If it's a gift to the U.S., that's different. But if it's a gift just to Trump, then I wouldn't be for it," John, from Houston, told Fox News Digital.

Another suggested it might be "ethically muddy" when asked about the gift.

"There's a lot of ethics that need to be discussed around that. I haven't really heard too much about it, but I would say, you know, a state accepting such a pricey gift on behalf of whatever. It might be a little ethically muddy," Krishna, from Detroit, told Fox News Digital.
