From the founding of Southern (1858), all teachers were REQUIRED to adhere to the Abstract of Principles; which not only affirms the basics of the faith, but also affirms at minimum a mild form of Calvinism. The document they have been required to affirm (LONG before 2000!!), is in many ways MORE strict than the BF& M.
After liberal theologians began to take Southern over, then they began making professors sign it, because the professors were lying in order to get teaching positions.
GOOD FOR THEM. No SEMINARY should allow a teacher that denies the basic tenets of the faith. Would you allow someone to teach at a medical school, if they denied the necessity of scalpels, and asserted instead that surgeons should use butter knives??! Any professor that denies the virgin birth, or the deity of Christ, or the resurrection, should be instantly let go.
They can use whatever they want. I find it ironic/odd/funny that a member of the committee that put together the 2000 version, won't use it at the school where he is president. Special dispensation for him I guess
I would also say that the Abstract is not mildly Calvinistic, it is full blown, double predestination Calvinistic. Which, though I would disagree with it, is at least logically consistent with Calvinistic thought.
