Zantorzi, that is a great question, and it is a critical element in understanding Moody. 

 I am a Bible/Theology graduate of MBI.  I can confirm that the school has very strong theological commitments to Pre-tribulational, Pre-millenial Dispensationalism.  These ideas are not often communicated, nor are they openly debated at the school.  Faculty who changed their opinions on these matters have been dismissed from the Institute, and graduates are required to sign a statement confirming their adherence to this theological position, before receiving their diploma / degree. 

 Links to these would be very helpful to anyone trying to better understand this school.
