Kai Höss walks to the podium every Sunday at a small church in Germany to share a message of salvation and God’s grace and forgiveness. 

He’s the lead pastor at the Bible Church of Stuttgart, a non-denominational church that serves the English-speaking international community as well as U.S. service members and their families who are stationed in the area.

He’s also the grandson of former Auschwitz Commandant Rudolf Höss, a Nazi official who oversaw the mass murder of an estimated 1.1 million people, the majority of them Jews, at the notorious extermination camp in southern Poland.

Höss spoke with Fox News Digital from his home in Germany to share his thoughts on antisemitism today and how he reconciles his Christian faith with what his grandfather did nearly 80 years ago.

He was raised in a non-Christian home with non-believing parents, but his Grandma Caroline was a believer who «understood Christ» and the Gospel. 

«I thought she was really weird,» Höss admitted.

He graduated from school, trained as a chef, joined the military and then studied hotel tourism management. He worked abroad for roughly 20 years, spending most of his time with big-name hotel chains like Sheraton and Shangri-La.

«I was a young urban professional full of myself, in love with myself, you know, Rolex, golden Amex, Mr. Cool, going to clubs, out every night. That was my life,» he said.

It wasn’t until a medical operation went wrong that he turned his life around. He found a Bible in the hospital room, initially telling himself that he wasn’t going to read it, but continued book by book.

He was saved in Singapore in 1989. «God saved a wretch like me, you know? And that’s what he does. And it never stops. His grace abounds,» Höss said. 

The father of four openly speaks about his family’s past and his salvation and goes to schools to share his story and speak out against antisemitism.

Höss was in sixth or seventh grade when he discovered that Rudolf Höss was his grandfather, which left him feeling deeply ashamed.

«I didn’t go around telling people, ‘Hey, you know, I’m the grandson of the greatest mass murderer in human history,’» he told Fox News Digital. «So, I just kept it quiet.»

After he became a Christian, he felt compelled to share his grandfather’s dark legacy and share a message of forgiveness, grace and reconciliation. He shared his testimony at a U.S. military retreat in Germany, where he was embraced by a Jewish military officer whose family had been murdered in Auschwitz.

«I started thinking, ‘How can I give something back? How can I do something to’ – I know I can’t make it undone. I can’t reverse history, but I thought, you know, I can do something. I can just love them and what I can do, I can proclaim the truth from God’s word to Christians,» Höss said. 

Through Jesus Christ, he believes God’s grace is able to redeem even the darkest past. 

When speaking to students in Germany, Höss addresses antisemitism by drawing connections between the past and the present, specifically referencing World War II, his grandfather’s role and the power of hate.

He explains the concept of social Darwinism, which was used by the Nazis to justify their belief in racial superiority. He explains how Darwin’s theory of evolution was misapplied to humans, leading to the idea that certain races were «stronger» and more «superior» than others and thus had the right to dominate or eliminate «weaker» races.

Höss emphasized that this false ideology fueled much of the hatred against Jews, along with other marginalized groups, during World War II.

He connects his presentations to social media platforms today and how TikTok, for example, can be highly influential, especially with its short, emotionally charged clips. He warns students about the danger of being swayed by superficial or biased content, emphasizing the importance of thinking critically and not simply swallowing information «hook, line and sinker» without considering the deeper truths or questioning the narrative.

«One of my friends called it TikTok mentality, TikTok brains, you know, you get these endorphins, you get these, you know, little hormone boosts every time you see a little clip. Boom, boom, boom, boom, boom. And then it gets so addictive, right? And people get filled with the wrong idea. They don’t look for deeper truth. They don’t analyze,» he told Fox News Digital.

Höss reacted to anti-Israel protests that erupted on U.S. college campuses after Hamas’ Oct. 7 attack on southern Israel, noting how much of the support for violence on campuses comes from people acting emotionally, often without a full understanding of the historical and political complexities of the situation.

Julia Wax, a Georgetown University law student, told «Fox & Friends» in the wake of Oct. 7 that college campuses are a «hostile environment» for Jewish students. 

«People are scared to go to class. You have to sit next to classmates who are posting antisemitic rhetoric, who are promoting rallies that spew antisemitic rhetoric. People are scared, and the universities are not doing their part, and they’re not stepping up, and they’re staying silent,» Wax said.

Höss told Fox News Digital he hears people chanting «From the river to the sea,» but if you ask them what that river or sea is, «they have no idea.» «They want to be part of something. They feel good about it. They get the basic message, the narrative. They’ve never really questioned both sides of the coin, so they don’t really have the full information. They’re not really interested because, again, it’s emotional. It’s an emotional response.»

He critiqued how people, driven by ideologies or emotional narratives, can turn hatred into action, leading to harm and violence against others.

«We get infiltrated by ideas, ideologies, thoughts, emotions. And then we start going all for it. We go right out there, and we turn these thoughts into actions. And one of them is hatred and hatred turning into bloodshed. And that’s exactly what we see on the campuses. We see people are willing to go out for this idea and do bad things. I mean, [they] don’t realize that this Jewish person there is just, you know, a normal person like they themselves,» Höss said.

«He’s made of flesh and blood, right? He’s a student. He’s just a normal person. And here I hate someone because of something a government did somewhere on the other side of the planet, you know? And is everything that happened right? Perhaps not, you know, in that whole conflict there,» he added, referring to the Israel-Hamas war. «I hope they’re going to come to a point now where this whole thing sort of slows down and people can help.»

Höss and his father traveled to Auschwitz three years ago when they were filming the HBO documentary «The Commandant’s Shadow.» They met with Holocaust survivor Anita Lasker-Wallfisch in her home and came to terms with Rudolf Höss’ murderous past. 

«We pray for her,» he added. «And I feel so privileged and thankful, humbled that we were allowed to go there and my dad and I and just see her and spend time with her. A person that had suffered so much under my grandfather’s cruel, cruel system in that concentration camp.»

Höss has plans to speak at a synagogue in Freiburg, Germany, in January as part of the commemoration services for the 80th anniversary of Auschwitz’s liberation. 

«[It’s] an amazing opportunity to speak up and to be part of something like that,» he told Fox News Digital.
