By religious university, I am assuming you mean you would be studying to become a preacher or pastor? I would not attend unless I had been "called" to go into that field by the man above. Hopefully, that is true for everyone.
No, I meant a private university where the college students choose to attend due to religious preference. There are plenty out there. You can study a wide range of subjects, not just religious studies. For some schools, it's a requirement to attend the church services there as well. One example is Pepperdine in Malibu, CA which has an association with the Church of Christ.
