As a Religious Studies major as an undergrad, and a Theology student in grad school, I kind of think I am qualified to tell you -- they aren't the same.
Religious Studies is typically the study of religion, and there are hundreds of religions and an infinite number of types of religious experiences. Theology is the study of God, typically under the umbrella of one specific religion or academic discipline.
Further, Religious Studies can legally be offered at a state school, Theology cannot.
Are you attending a Baptist college?
