Lewis, the son of Alabama sharecroppers, played an instrumental role in the passage of the landmark Voting Rights Act in 1965 and went on to serve more than three decades in Congress representing the 5th Congressional District of Georgia.
Lewis died on July 17 at 80 after a months-long battle with pancreatic cancer.
In some of his final words, Lewis wrote about the current climate of America and the need to keep fighting for justice in an op-ed for The New York Times, which was to be published on the day of his funeral.
"Though I may not be here with you, I urge you to answer the highest calling of your heart and stand up for what you truly believe," Lewis wrote. "In my life I have done all I can to demonstrate that the way of peace, the way of love and nonviolence is the more excellent way. Now it is your turn to let freedom ring."
Here is how the service developed. All times Eastern.
2:36 p.m.: Lewis' casket brought out of church
The casket of Rep. John Lewis was brought out of the Ebenezer Baptist Church and will head to its final resting place.
Lewis will be buried at South View Cemetery in Atlanta, Georgia.
2:06 p.m.: Obama delivers eulogy
President Barack Obama delivered the eulogy for Rep. John Lewis, remembering his accolades that changed the course of history and looking forward to the world the congressman fought for.
"So many Americans owe a great debt to John Lewis and his forceful vision of freedom," Obama said.
He specifically noted that Lewis' desegregation campaign in Nashville was the first successful one in any major city in the South and that Lewis led the march from Selma to Montgomery.
"America was built by John Lewises," Obama said. "He, as much as anyone one in our history, brought this country a little bit closer to our highest ideals, and someday when we do finish that long journey towards freedom, when we do form a more perfect union, whether it's years from now or decades or even if it takes another two centuries, John Lewis will be a founding father of that fuller, fairer, better America."
Obama noted the severe injuries Lewis and many others suffered at the hands of troopers during the Selma-to-Montgomery march.
"I imagine initially that day the troopers thought they'd won the battle," he remarked.
But Lewis returned, as did more marchers who were able to pass through, Obama noted. The message of the marchers eventually made it to the White House, and President Lyndon B. Johnson passed the Voting Rights Act.
While Obama lauded the accomplishments, he also urged people to know the fight is far from over.
"George Wallace may be gone, but we can witness our federal government sending agents to use tear gas and batons against peaceful demonstrators," he said, referring to the former governor of Alabama who ordered troopers to use violence against the marchers.
Obama added that while "we may no longer have to guess the number of jelly beans in a jar in order to cast a ballot," there are "those in power who are doing their darnedest to discourage people from voting by closing polling locations and targeting minorities and students with restricted I.D. laws and attacking our voting rights with surgical precision. Even undermining the postal service in the run-up to an election that's going to be dependent on mail-in ballots so people don't get sick."
Though Obama did not explicitly name President Donald Trump, his comments come hours after Trump suggested delaying the election in a tweet because of the false notion that mail-in voting would amount to fraudulent votes.
Obama ended his speech by saying that Lewis was hopeful after seeing the recent protests against police brutality and systemic racism in the United States.
Lewis "could not have been prouder" of young people "standing up for equality and protecting the right to vote," Obama said. He remarked he told Lewis, "John, those are your children."
Obama said the protests showed the courage that Lewis taught -- courage that came from turning towards others, not away from them.
"What a gift John Lewis was," Obama concluded. "We are all so lucky to have had him walk with us for a while and show us the way. God bless you all. God bless America. God bless this gentle soul who pulled it closer to its promise."
1:39 p.m.: Let's not give up,' Lewis' niece urges
Sheila Lewis O'Brien remembered Rep. John Lewis not only as a revered civil rights icon and congressman, but as a family man.
Calling him "Uncle Robert," she said she wanted to pay tribute "to a man who was larger than life."
"For the last 60 years as a nonviolent civil rights activist, he was a voice for those who couldn't speak, the feet for those who couldn't walk and the champion of injustice for those that couldn't fight," O'Brien said.
She said it was clear why Lewis' life had been so celebrated in the past few days and urged Americans to continue her uncles' fight.
"Let's continue this celebration of life by taking up the baton he has now laid down and endeavored to get into trouble, good trouble, necessary trouble. Let's not give up."
1:29 p.m.: Lewis remembered as a boss by deputy chief of staff
Rep. John Lewis broke down barriers in the workplace and created a family among his employees, his deputy chief of staff said.
"We were a little family, a little enclave," Jamila Thompson said. "A lot of drama, a lot of fun and so much love."
Thompson said Lewis made each staff member feel "special" and "worthy" while working for him.
"He allowed us to be our true and authentic selves, just the very best version," she said.
Thompson, like others, also encouraged the American people to vote in November to honor Lewis.
"Be the best version of yourself. Be informed. Stay engaged. Even though the work is hard," Thompson concluded. "If you are of age and eligible, for the love of God, please vote."
12:59 p.m.: Xernona Clayton recalls Lewis' love story, urges kindness
Xernona Clayton, the founder of the Trumpet Foundation, spoke of the love story between Rep. John Lewis and his late wife Lillian Miles Lewis.
Clayton said she had set the two up. Though both were initially hesitant, Clayton said when they finally had the chance to spend time together, their bond was clear.
"Lillian and John stayed married. I put it together, but it lasted 43 years," she said warmly. "That's not a bad record, is it?"
Clayton also spoke of their son, John Miles Lewis, who is her godson, saying through their love, the couple showed him love.
Clayton also urged those who want to honor Lewis, not just to listen to his praises but to "do something about the man he asked us to be in ourselves, and that is to be kind to everybody, to love everybody."
She ended her speech with a clear message: "I want to advise you and admonish you, to really give meaning to the John we love: Vote."
Bill Campbell, the former mayor of Atlanta, similarly encouraged Americans to vote in November to truly honor Lewis.
12:40 p.m.: 'Black lives matter,' Rev. James Lawson says in powerful speech
Rev. James Lawson Jr., a mentor for Rep. John Lewis and nonviolent activist, said the only way to honor the late congressman's life is to ensure equality.
"We need the Congress and president to work unfalteringly on behalf of every boy and every girl, so that every baby born on these shores will have access to the tree of life," Lawson, 91, said. "That's the only way to honor John Robert Lewis. No other way."
Lawson also had a simple message for the congregation: "Black lives matter."
He said that while Lewis was shaped by his early preachings as a boy, he was also shaped by "the malignancy of racism in Troy, Alabama," where Lewis was born.
"There formed in him a sensibility that he had to do something about it," Lawson said.
Lawson said he, like Lewis and others, such as civil rights pioneer C.T. Vivian, who also recently died, had a similar experience.
"I maintain many of us had no choice to do, but we tried to do, primarily because at an early age we recognized the wrong under which we were forced to live," he said, "and we swore to God that by God's grace we would do whatever God called us to do in order to put on the table of the nation's agenda this must end."
12:27 p.m.: Crowd gathers outside church
A crowd of about 100 people gathered outside the church where Rep. John Lewis' funeral was underway.
Because of the coronavirus pandemic, only about 240 people were allowed in the Ebenezer Baptist Church.
12:18 p.m.: Pelosi says Lewis' mission was ''nonviolently insisting on the truth'
House Speaker Nancy Pelosi spoke of her friend and colleague Rep. John Lewis, honoring his life and remembering his legacy.
"When John Lewis served with us, he wanted us to see the civil rights service and the rest through his eyes," Pelosi said, noting he took members of the House to Selma for two decades. "He wanted us to see how important it was, how important it was to understand the spirit of nonviolence."
Pelosi also spoke about Lewis' legacy and mission, invoking the Sanskrit word "satyagraha."
"It means nonviolence, and it means insistence on the truth. And that is what John Lewis was all about: nonviolently insisting on the truth," Pelosi said.
Through tears, she told fellow mourners that he always worked toward a "more perfect union," with many messages specifically to young people.
Pelosi ended her speech with an image of a double rainbow, saying that on his last night at the Capitol, one appeared, despite it not having rained.
"He was telling us, 'I'm home in heaven,'" Pelosi said. "We always knew he worked on the side of the angels, and now he is with them."
12:03 p.m.: Clinton calls for all to 'salute, suit up and march on'
Former President Bill Clinton said Rep. John Lewis left the world with "marching orders" to "keep moving," referencing his op-ed in the New York Times, which was published on the day of his funeral.
"I just loved him. I always will, and I'm so grateful that he stayed true to form: He's gone off yonder and left us with marching orders," Clinton said. "I suggest -- since he's close enough to God to keep his eyes on the sparrow and us -- we salute, suit up, and march on."
Clinton also recalled Lewis' ability to make "good trouble," as well as his "uncanny ability to heal troubled waters."
The former president also spoke about Lewis' insistence for nonviolence, saying Lewis would rather keep moving in the right direction "without hatred in his heart" and with open hands rather than "clenched fists."
Clinton highlighted the humble spirit of the civil rights icon, noting that that great achievements of a share-croppers son from Troy, Alabama is a testament to the greatness of the human spirit and an embodiment of American tenacity.
"I think it's important that all of us who loved him remember that he was after all, a human being," Clinton said. "A man like all other humans born with strengths that he made the most of when many don't. Born with weaknesses that he worked hard to beat down when many can't, but still a person. It made him more interesting, and it made him in my mind, even greater."
11:46 a.m.: Bush delivers remarks
Former President George W. Bush said that while he and Rep. John Lewis had their differences, "we live in a better and nobler country because of John Lewis." Bush said that Lewis' lifelong work does not end with his death and the fight is not over.
"The story that began in Troy [where Lewis was born] isn't ending here today, nor is his work," Bush said. "He will live forever in the hearts of Americans who act justly, love mercy and walk humbly with their God."
Bush was the last president to re-authorize the Voting Rights Act. Wearing a picture of Lewis on his lapel, Bush thanked the late congressman's family for inviting him to the funeral.
11:28 a.m.: Rev. Dr. Bernice King invokes words of MLK, says Lewis' fight for justice will continue
Rev. Dr. Bernice King, the youngest child of civil rights icon Dr. Martin Luther King Jr., honored the life of Lewis with her father's words.
"Death is not a period that ends this great sentence of life, but a comma which punctuates it to a lofty and higher significance," King said, quoting her father.
King thanked God for "honoring us with his presence and allowing our lives to intersect with his." She also invoked the words of Lewis, saying that those fighting for justice would continue to make "good trouble as long as [God] grants us the breath to do so."
She prayed for "good trouble" to dismantle white supremacy, protect Black bodies and ensure Black lives have equitable representation and power in every arena, and until "this nation truly becomes a compassionate nation."
11:20 a.m.: Funeral service is underway, Lewis remembered as 'true American patriot'
Funeral services have begun for Rep. John Lewis. Rev. Dr. Raphael G. Warnock, the senior pastor at Ebenezer Baptist Church, started with the welcoming remarks, remembering Lewis for his lifelong fight as a civil rights icon and saying he is an emblem of a true hero.
"When there is so much political cynicism and narcissism that masquerades as patriotism, here lies a true American patriot who risked his life for the hope and promise of democracy," Warnock said.
Warnock added that although the news cycle happens at a "dizzying pace" between the pandemic and protests for racial justice, "time stood still. The nation takes it time to remember him."
"He became a living, walking sermon about truth-telling and justice-making, and he loved America until America learned how to love him back," he said.
9:38 a.m.: Speakers include Obama, Bush, Clinton, Bernice King, Pelosi
Tributes for Rep. John Lewis will be delivered by former Presidents George W. Bush and Bill Clinton, as well as Speaker of the House Nancy Pelosi, according to a copy of the funeral program.
Obama, as reported Wednesday, will deliver the eulogy.
Rev. Dr. Bernice King, the CEO of the King Center and youngest child of civil rights leaders Dr. Martin Luther King Jr. and Coretta Scott King, will lead the funeral in a prayer, the funeral program showed.
Other speakers paying tribute include Bill Campbell, former mayor of Atlanta; Jamila Thompson, deputy chief of staff for Lewis; Xernona Clayton, founder of the Trumpet Foundation; and James M. Lawson, an activist.
Funeral ceremonies began last Saturday in Lewis' hometown of Troy, Alabama. On Sunday in Selma, 55 years after he and other demonstrators were beaten on "Bloody Sunday," Lewis crossed the Edmund Pettus Bridge for a final time. Where he was once met with batons, Lewis' casket saw salutes from state troopers.
