the American story not through the lens of politics or tribe. They saw it as it surely looked to John Winthrop and every weary traveler who has ever approached American shores—rocky, imperfect, and unknown, but expansive, limitless, and defiantly hopeful.

Since the beginning, immigration has been an affirmation of our success, not a threat to it. People risk everything to reach this land because they believe in our greatness—our fair laws, our good values, our promises and possibilities. We should not worry when the striving and suffering arrive on our shores; we should worry when they stop coming at all.

Today that legacy—our legacy—is being threatened, by the same chorus that met President Kennedy when he had the boldness to tackle the racialized quota system. Their voices sound familiar: Immigrants will flood our cities and towns. They will take our jobs. They will threaten our culture. They aren’t from here. They aren’t like us.

Fifty years later, those voices still have not updated their talking points. Fifty years later, our broken immigration system is still a source of oppression, of anguish, and of loss.

As I write this, thousands of immigrant children remain separated from their parents on American soil. They showed up at our border terrorized, desperate, and afraid. And in an act of unimaginable brutality, our government responded with terror of its own—taking infants and toddlers out of their families’ arms.

This is the human wreckage of American immigration policy. This is the trauma and torture that dark forces of nativism, supremacy, and prejudice have brought to bear in a land that staked its name on brighter, better things: equality, dignity and freedom.

This is the work that lies ahead, daunting and dangerous, but familiar, as President Kennedy reminds us in the pages that follow. We have been here before. We have spent generations battling those who would make America sharp and small and scared. We have risen, we have challenged, we have dragged ourselves toward a more perfect union.

We have done that by seeing a little of ourselves, our history, and our experience in others’ eyes. By choosing compassion and mercy and grace—not just because they are right, but because they are smart. Because we are richer and stronger and freer when we aim for less suffering, less trauma, less poverty, less prejudice.

There’s a great story that makes its way around Irish-American quarters here in Boston. In the midst of the Great Hunger in Ireland, the Choctaw Indian tribe of Oklahoma heard about the plight of the Irish; read about starving women and children dying along the roads, their mouths stained green with the grass they ate in desperate search of nourishment.

They collected $170 and sent it to Ireland for famine relief, mindful of their own struggles and the Trail of Tears that had led them less than 20 years earlier to their new home in Indian Territory. From the painful lessons of their own past, they were called to help people they didn’t know, who looked different, spoke different, were different.

But who suffered just the same.

Today we summon that example. We summon the feelings of fear, loss, desperation, and isolation that visit each of us in different ways no matter our privilege or protection. In that shared humanity we find our empathy. We find our strength. We find the proud and dusty pages of our story that prove ours is a country unafraid to open, extend, and expand. We find our voices—like the hundreds of thousands of Americans who have risen up in response to the current immigration policies and said: No. Not on my land. Not in my name.

They have donated money and time and skills to reunite broken families. They have fostered young children left alone on our shores. They have taken to the streets and the courts, state legislatures and halls of Congress, to demand something better, fairer, kinder, and stronger from the government that represents them.

President Kennedy would be proud. It is the call not just to action but to decency that echoes through these pages. It is the confident, charismatic country he believed in. Most important, it is the simple Gospel he knew would bind us to each other through time and space and generations—no matter creed or country, color or class.

“For I was hungry and you gave me food, I was thirsty and you gave me drink, I was a stranger and you welcomed me.”
