A Wisconsin-based organization has filed a complaint with Clemson University citing "serious constitutional concerns about how the public university's football program is entangled with religion."The Freedom From Religion Foundation touts itself as the “largest national organization advocating for non-theists,” and says its mission is to promote separation of church and state and educate the public on matters relating to atheism, agnosticism and nontheism.Clemson’s football program is the organization’s most recent target, but in the past they have successfully fought against nativity displays on city hall properties. In 2008, the FFRF filed a lawsuit against the U.S. government over the statute establishing the National Day of Prayer, among other actions. In March, the FFRF joined 19 other plaintiffs in a lawsuit against the U.S. Treasury Department and other government officials in March demanding that the phrase “In God We Trust” be removed from the nation’s currency.Last Thursday, FFRF sent a letter of complaint to Clemson after having filed an open records request with the university in February."Christian worship seems interwoven into Clemson’s football program," wrote FFRF Staff Attorney Patrick Elliott. "We are concerned that this commingling of religion and athletics results, not from student initiative, but rather from the attitudes and unconstitutional behaviors of the coaching staff."The FFRF complaint says Coach Dabo Swinney invited James Trapp to become team chaplain, which they say did not follow procedure that allows student groups to select their chaplain. It says Trapp is allowed access to the whole team between drills for Bible study.  It also accused Swinney of showing preference to players who believe as he does, creating a “culture of religious coercion.”The FFRF also complains that there are Bible quotes displayed and sessions on being baptized held in the athletic building. They also dislike that Trapp, as a paid university employee, “refers to himself as a minister,” promotes religion, and serves as a Fellowship of Christian Athletes representative, and keeps Bibles in his office for distribution.The FFRF also says that Swinney confirmed that the entire team would attend an FCA breakfast in December where three players would “testify,” and the team and coaches attended a church together in August 2011 and that Swinney regularly holds team devotionals that are organized by the chaplain and led by coaches.The FFRF wants Clemson to require Swinney and Trapp to stop team prayers, sermons, Bible studies and group church attendance by the team.To read the FFRF full release, click here.Clemson University Chief Public Affairs Officer, Cathy Sams released this statement:"We believe the practices of the football staff regarding religion are compliant with the Constitution and appropriately accommodate differing religious views."Participation in religious activities is purely voluntary, and there are no repercussions for students who decline to do so. We are not aware of any complaints from current or former student-athletes about feeling pressured or forced to participate in religious activities."Clemson takes very seriously its obligation to provide a comprehensive program for the development and welfare of our student-athletes – which encompasses academic, athletic and personal support, including support for their spiritual needs."We will evaluate the complaints raised in the letter and will respond directly to the organization, but we believe FFRF is mistaken in its assessment. The Supreme Court has expressly upheld the right of public bodies to employ chaplains and has noted that the use of prayer is not in conflict with the principles of disestablishment and religious freedom."After a similar FFRF complaint earlier this year, Appalachian State University, in Boone, N.C., told a coach to stop proselytizing student athletes.  The coach left ASU for unrelated reasons, but the university’s general counsel said ASU has reminded each of its coaches that the previous football coach’s behavior is "not acceptable."
