Samaritan's Purse CEO Franklin Graham on Tuesday openly asked, "Why has the Democratic Party turned its back on God?"

And then he answered with, "Many politicians don't want God in any part of their politics or our country's business because His standards condemn their sin."

The judgment came on Graham's Facebook page: "Yesterday the New York Times reported that since gaining the majority, Democrats have been making changes to House traditions, including sometimes omitting the words 'So help me God' from the swearing-in oath. Rep. Steve Cohen of TN said, 'I think God belongs in religious institutions: in temple, in church, in cathedral, in mosque – but not in Congress.

"I would say to Rep. Cohen and other politicians, basically what Rep. Garret Graves of LA said – We need more of God, not less! What Rep. Cohen is suggesting is just what Communism did in Eastern Europe and is still doing in places around the world like Cuba. Communism only allows worship inside approved churches," Graham wrote.

"God is our Creator and the maker of the universe. He is present everywhere; He is not limited to churches or temples. Back to my initial question. The root of the issue is that many politicians don’t want God in any part of their politics or our country’s business because His standards condemn their sins."

The New York Times reported Rep. Diana DeGette, D-Co., chairman of the Energy and Commerce oversight subcommittee, was dictatorial when the reference to God was left out.

"This is the oath we use," she stated, "and that's the oath we’re going to use today."

Rep. Liz Cheney, R-Wyo., denounced the move, telling Fox News that House Democrats "really have become the party of Karl Marx."

The Times claimed that DeGette was "reading from the same committee decorum rule book that her Republican predecessor, Rep. Gregg Harper of Mississippi, had used."

Clint Cooper wrote in a commentary at the Times Free Press that the Democrats' agenda isn't complicated.

"Invoking God would mean the existence of an entity more powerful than the federal government. And that's not what Democrats want to consider," he wrote.

He explained, "The words, according to an article in the William & Mary Law Review, are 'an abbreviated form of the oath, 'So may God help me at the judgment day if I speak true, but if I speak false, then may He withdraw His help from me.'

"No God, no conscience, then no need for truth," he said.

It's far from the only time the Democrats have had issues with God.

At their 2012 national convention, God was left entirely out of the party's platform. When Gov. Ted Strickland moved to restore the reference, the delegates voted him down.

Listen to the exchange:

Graham has been busy schooling politicians this presidential election season about faith.

One lesson this week was addressed to Democratic presidential hopeful Cory Booker, who complained in an interview that the idea of "thoughts and prayers" helping someone is just "bull----."

"Democratic presidential candidate Cory Booker obviously doesn’t know the power of prayer," Graham wrote on Facebook.

"He said that thoughts and prayers after gun violence is BS. That couldn't be farther from the truth. When people have lost loved ones, they need the comfort and strength that can only come from God."

He explained: "The solution for the problem in this country is much deeper than more laws. The Bible says, '…out of the heart proceed evil thoughts, murders, adulteries, fornications, thefts, false witness, blasphemies …' (Matthew 15:19). Jesus' words are true, and only He can transform the human heart. I'm sorry that some of our politicians have turned their backs on God. I'm going to continue to pray for victims of violence and their loved ones, and I'm going to continue to urge others to pray for them when these tragedies occur. Unless our nation calls on God and turns our heart toward Him, violence of all types will only continue to escalate."

The Blaze describedBooker's comments as a "passionate rant about gun control where he mocked those offering 'thoughts and prayers' with an expletive."

"So, when I'm president of the United States, I'm taking the fight to this issue like folks will never seen before because we're better than this as a country. It's a uniquely American problem, no other country have this kind of carnage," Booker stated. "More people in my lifetime have died in this nation, uh, due to gun violence than in all the wars and revolutionary wars to now. We're not gonna give thoughts and prayers, which to me is just b------- and I'm sorry to say that as a man of faith, but I was taught that faith without works is dead."

Cory Booker says thoughts and prayers are "bulls***" The Democratic Party has gone from mocking us for "clinging to guns or religion" to saying we will take your guns and your religion is "BS."

Graham previously rebuked Democratic presidential hopeful Pete Buttigieg, the mayor of South Bend, Indiana, for his perspective on homosexuality.

Buttigieg has caught Graham's attention twice, the first time for attacking Vice President Mike Pence's faith.

Then Graham responded on Facebook to Buttigieg's claim that God doesn't favor one political party over another.

"Presidential candidate and South Bend Mayor Pete Buttigieg is right – God doesn't have a political party. But God does have commandments, laws, and standards He gives us to live by. God is God. He doesn't change. His Word is the same yesterday, today, and forever," Graham wrote.

"Mayor Buttigieg says he is a gay Christian and he wants to unite people behind him. I'm sure there will be many people who will want to follow. But as a Christian I believe what the Bible says. God's Word defines homosexuality as sin, something to be repentant of, not something to be flaunted, praised, or politicized. The Bible defines marriage as between a man and a woman – not two men, not two women.

Graham noted Buttigieg also declared "the core of faith is regard for one another."

"We are definitely to support and help each other – no question," Graham said. "But that does not come above believing and being obedient to what God says is truth. Without that foundation, we really can't help anyone in a way that impacts their eternity. The core of the Christian faith is believing and following Jesus Christ, who God sent to be the Savior of the world – to save us from sin, to save us from hell, to save us from eternal damnation."

And in January, Graham urged Roman Catholic Cardinal Timothy Dolan of New York to take a stand against abortion by excommunicating New York Gov. Andrew Cuomo for signing a bill allowing abortion in any stage of pregnancy.

On Facebook, Graham noted Dolan told Fox News on Monday that Cuomo is "not going to be moved by this, so what's the use?"

"I call on my friend Cardinal Dolan to take a moral stand. Whether it moves the governor's calloused heart or not, it will have a great impact on not only the church in New York, but on the church worldwide," wrote Graham, also the CEO of Billy Graham Evangelistic Association.

"My question would be – if the church loses their moral voice, then what's the use? It's about standing for right over wrong, good over evil."
