Wheaton College, an evangelical Christian institution, has disciplined a professor who put on a head scarf in solidarity with Muslims and said they worship the “same God” as Christians.

The private liberal arts college in Wheaton, Ill., said in a statement on Tuesday that Larycia Hawkins, an associate professor of political science, had been placed on administrative leave over “significant questions regarding the theological implications” of recent remarks she made about the relationship between Christianity and Islam.

“As they participate in various causes, it is essential that faculty and staff engage in and speak about public issues in ways that faithfully represent the College’s evangelical Statement of Faith,” the statement said.

The college president, Philip G. Ryken, emphasized in a statement on Wednesday that Dr. Hawkins’s words, not her appearance in a scarf, were the issue. He said Wheaton had “no stated position on the wearing of head scarves as a gesture of care and concern for those in Muslim or other religious communities that may face discrimination or persecution.”
