Michael Bossman

As Vice President of Campus Operations, I am accountable to insure every campus around the world successfully accomplishes everything that the Lord expects from them. I am responsible to develop an infrastructure that will serve Ratio Christi as a world class operation, rivaling the best college ministries while setting the standard for Christian Apologetics, optimally delivered to young people around the world.

This system must insure that each Chapter Director on campuses around the globe has the tools necessary to facilitate proficiency in Christian Apologetics, allowing them to effectively multiply apologists through discipleship, training, mentoring, and developing a core group of students on their campus to become mature and capable apologetic leaders who impact their university and influence society with Christian values as they go on to establish careers. Success is measured as each RC Apologetic Club matures and this core team begins training other students, who then train other students, creating a ripple effect of intrinsic systemic growth.

There has never been a time in human history when there has been more scientific, philosophical, archeological and historical evidence supporting Christianity than today. Scripture provides an elegant and intellectually satisfying solution to modern scientific conundrums. The reasons for investigating the truth claims of Christianity have never been more compelling, necessitating a rigorous intellectual discussion at the university.

If we train just 2 university students in 1 year, and each of those students each train 2 more the following year, and we do this at every university where Ratio Christi has a club, in 10 years we will have an army of 1 Million apologetically trained young adults defending Christianity around the world!

We hope to ignite the next Great Awakening by initiating a Renaissance of Christian thinking in the University and we intend change the culture on campus to one that respects Christians as valued intellectual pillars in the college community, rational defenders of Christianity who demonstrate personal integrity and use well-reasoned thought to defend and uphold the truth of the Bible.

I am honored to join forces with the dedicated Ratio Christi Team. Like Caleb (Num. 13:30-14:9), I resolutely refuse to lose hope even though the land is full of "giants". Our God will deliver us! We will overcome! But we each must do our part to engage skeptics using all of our gifts and abilities in our efforts to reclaim the mind for Christ at the university.

”A person standing alone can be attacked and defeated, but two can stand back-to-back and conquer. Three are even better, for a triple-braided cord is not easily broken” Ecc. 4:12. We can be victorious together, but not by sitting on the sidelines hoping things will someday change. Our enemies hope you remain idle, comfortably watching from a safe distance; instead, break out, get involved in the struggle, join us as we claim this victory for Christ!

In 2004, he earned his J.D. from the Regent University School of Law. Tedesco is admitted to the State Bar of Arizona; the Supreme and District Court of Arizona; the District Court of Colorado; the U.S. Courts of Appeal for the 2nd, 3rd, 5th, 6th, 7th, and 9th Circuits; and the U.S. Supreme Court. He serves on the Board of Ratio Christi.

He has extensive experience litigating religious freedom for Christian students, faculty, and staff at public schools, colleges, and universities across the nation. He serves as senior legal counsel and the director of the Secondary School Project with Alliance Defending Freedom at its headquarters in Scottsdale, Ariz., directing public school litigation efforts for the Center for Religious Liberty.

Since joining Alliance Defending Freedom in 2004, Tedesco has passionately defended religious liberty, free speech, and the sanctity of human life. He currently specializes in protecting the First Amendment freedoms of students and faculty at public colleges and universities nationwide.

Tedesco has numerous courtroom victories, including Krestan v. Deer Valley Unified School District, where he prevailed in defending a Christian club’s right to publicize meetings via PA announcements. In O.T. v. Frenchtown Elementary School District Board of Education, he successfully argued that a student should be allowed to sing a Christian song during a school talent show. He obtained a favorable court ruling in Ward v. Polite on behalf of a Christian student unfairly expelled from a graduate counseling program because she was unwilling to affirm sexual relationships that are contrary to biblical teachings. He authored a friend-of-the-court brief in Van Orden v. Perry, in which the U.S. Supreme Court ruled that a carved granite display of the Ten Commandments on the Texas State Capitol grounds did not violate the Establishment Clause. He was also the primary brief writer in Arizona Christian School Tuition Organization v. Winn, where the Supreme Court ruled that taxpayers who are offended cannot make unwarranted constitutional challenges. This significant victory curtailed one of the main avenues through which “offended observers” filed lawsuits under the federal Establishment Clause despite having no personal legal injury.

A staunch pro-life advocate, Tedesco’s career path was shaped by the heated debates he had on abortion with his high school friends. After studying Roe v. Wade, he discovered a love of constitutional law and our country’s legal heritage. He continued to be an activist in college, taking on the homosexual agenda. He experienced first-hand, as do so many of his current clients, the vilification and mistreatment of Christians for expressing their faith on campus. Without a doubt, Tedesco knew he needed to pursue a law degree and defend religious freedom.

Tedesco has numerous media appearances, including numerous radio and print interviews and as a guest on Fox News Channel’s America’s Newsroom and Fox and Friends. He has also published an article in the Pepperdine Law Review.
