Catholic schools tend to impose rules based on the teachings of the Catholic faith.

However, when administrators at Boston College decided to crack down on student-organized workarounds to the campus’ faith-based rules on contraception, it ran afoul of one activist civil rights organization.  Eric Owens explains in The Daily Caller.

Official Roman Catholic doctrine has long stood athwart artificial contraception, yelling stop. And if you’ve ever attended a Catholic university, you know that birth control can be pretty much impossible to obtain on campus as a result.

You’ll probably have to walk up the street to a convenience store for condoms. You might even have to buy those condoms with your own money.

At Jesuit-affiliated Boston College, an unofficial campus group has been attempting to skirt the Catholic Church’s contraception doctrine, reports The group, Boston College Students for Sexual Health, has been conducting a network of “safe sites” in dorm rooms and at other on-campus locations where students can receive free condoms — and lubricant! — on the down low.

This underground condom railroad has been in operation since 2009, according to NBC News.

It’s unclear how long the administration has known about the group. However, on March 15, Paul Chebator, the dean of students, and George Arey, the director of student life, sent an email to the students behind the shadowy condom operation.

“The distribution of condoms is not congruent with our values and traditions,” the email read, according to NBC News. “We do need to advise you that should we receive any reports that you are, in fact, distributing condoms on campus, the matter would be referred to the student conduct office for disciplinary action by the university.”

Senior Lizzie Jekanowski, who chairs Students for Sexual Health, told NBC News that before the email her group had maintained an “an open and positive relationship” with school officials.

“None of our actions have changed at all in the past four years,” she said. “It came out of nowhere.”

Naturally, the American Civil Liberties Union has also inserted itself into the fray.

Sarah Wunsch, a lawyer with the ACLU of Massachusetts, maintains that the school’s actions contravene the Massachusetts Civil Rights Act.

“Our view is that Boston College has a First Amendment right to explain, advertise and persuade students of their views, but they have gone a step further by threatening these students,” Wunsch told NBC.

“BC is saying that they’re a private university, so we can do what we want,” the ACLU advocate told The Boston Globe. “But that’s actually not true.”
