"There should not be fear," Trump said Jan. 20. "We are protected and we will always be protected. We will be protected by the great men and women of our military and law enforcement, and, most important, we will be protected by God."
In signalling a new era for the United States, "at the bedrock of our politics will be a total allegiance to the United States of America, and through our loyalty to our country, we will rediscover our loyalty to each other," Trump said in his 15-minute address. "When you open your heart to patriotism, there is no room for prejudice. The Bible tells us how good and pleasant it is when God's people live together in unity. We must speak our minds openly, debate our disagreements honestly, but always pursue solidarity. When America is united, America is totally unstoppable."
He said Americans of all stripes harbour common hopes and dreams.
"We all enjoy the same glorious freedoms," Trump said, "and we all salute the same great American flag. And whether a child is born in the urban sprawl of Detroit or the windswept plains of Nebraska, they look up at the same night sky, they fill their heart with the same dreams, and they are infused with the breath of life by the same almighty Creator."
Much of the rest of Trump's inaugural address restated the themes he used in his presidential campaign, remarking repeatedly that the nation and its citizens would be his top priority as president.
"Today we are not merely transferring power from one administration to another or from one party to another," Trump said from the west front of the Capitol, "but we are transferring power from Washington, D.C., and giving it back to you, the people."
He added, "This moment is your moment. It belongs to you. It belongs to everyone gathered here today and everyone watching all across America. This is your day, this is your celebration, and this, the United States of America, is your country."
Trump distilled the ills he saw in the United States: "Mothers and children trapped in poverty in our inner cities, rusted-out factories scattered like tombstones across the landscape of our nation. An education system flush with cash but which leaves our young and beautiful students deprived of all knowledge. And the crime and the gangs and the drugs that have stolen too many lives and robbed our country of so much unrealized potential. This American carnage stops right here and stops right now."
The 45th president, who is a Presbyterian, said: "From this day forward, it's going to be only America first. America first. Every decision on trade, on taxes, on immigration, on foreign affairs will be made to benefit American workers and American families. We must protect our borders from the ravages of other countries making our products, stealing our companies and destroying our jobs. Protection will lead to great prosperity and strength."
Trump dwelt briefly on the United States' role in the world. "We will seek friendship and goodwill with the nations of the world, but we do so with the understanding that it is the right of all nations to put their own interests first," he said. "We do not seek to impose our way of life on anyone, but rather to let it shine as an example. We will shine for everyone to follow. We will reinforce old alliances and form new ones and unite the civilized world against radical Islamic terrorism, which we will eradicate completely from the face of the earth."
He vowed to Americans, "You will never be ignored again. Your voice, your hopes and your dreams will define our American destiny. And your courage and goodness and love will forever guide us along the way. Together we will make America strong again. We will make America wealthy again. We will make America proud again. We will make America safe again. And, yes, together, we will make America great again."
Before the swearing-in ceremonies, the Trump family attended a private prayer service St. John's Episcopal Church across Lafayette Square from the White House. Hosting the service has been a tradition for the church for at least a dozen presidential inaugurals.
At the Capitol, New York Cardinal Timothy M. Dolan was among a number of religious leaders taking part in the inauguration ceremonies. The cardinal read a passage from the Book of Wisdom.
Supreme Court Justice Clarence Thomas administered the oath of office to Vice President Mike Pence, then U.S. Chief Justice John Roberts administered the oath to Trump. Standing at the new president's side were his wife, Melania, and children Donald Jr., Barron, Ivanka, Eric and Tiffany.
