A crowd of more than 600 marched through downtown Milwaukee on Wednesday to protest the Trump administration's immigration policies at the U.S.-Mexico border.

The group mostly included members of the Evangelical Lutheran Church in America and Voces de la Frontera. Protesters rendezvoused at the downtown U.S. Department of Homeland Security office, the same location of a Thursday demonstration mostly attended by Jewish protesters.

The Lutheran group carried copies of "9.5 Theses" Wednesday, which explained their position on current immigration policy.

"The well-being and safety of children, including ensuring family unity and reunification, must be a priority," one of the theses reads. "Therefore we commit ourselves to an ongoing struggle for just immigration policies."

In likeness of Martin Luther — who founded the Lutheran faith and started the Protestant Reformation with his "Ninety-five Theses," which some believe he nailed to doors of the castle church in Wittenberg, Germany — the group attempted to tape their "9.5 Theses" to the DHS office front door, but an official promptly took it down.

The protest downtown Milwaukee on Wednesday is the third large demonstration in Milwaukee in the last month against the Trump administration's immigration policies. It follows Thursday's #NeverAgainIsNow protest that blocked ICE van access to the same DHS office and another in July held by members of the League of United Latin American Citizens.

Several members of the Lutheran group who protested on Wednesday said their faith calls them to protest current U.S. immigration policies. Paul D. Erickson, bishop of the Greater Milwaukee Synod of the ELCA, noted that welcoming immigrants is ingrained in the church's history.

"We are a church that ... wants to create a country in which immigrants, refugees and asylum seekers can find a home," Erickson said.

Other ELCA members said they were called into action because Mary and Joseph — the parents of Jesus — were refugees who fled their home. One member who traveled from Washington state, Gwen McQuaig, said the couple was told that "there was no room for them" before Mary gave birth to Jesus.

Others members said they can no longer stand idly by as immigration policies unfold at the border.

"It's been kind of scary over the last few years, and I have never seen anything like this before in this country," said Marj Ellis, a protester from Ohio and an ELCA member. "I'm not one for doing much, but I have to. I've finally decided that I have to get out there. I have to start doing everything because it seems like no one is doing anything."
