Not much of a shock that one would come out of WTS a anti-dispensationalist after that indoctrination.
About as much shock as a Dallas theological Seminary graduate leaving as a dispensationalist.
Not as many as you might think, with the overtaking of DTS by the progressive dispensationalists (aka covenant theology lite). I’m always amazed at the number of DTS grads in non-dispensational churches/positions. Many of the best and brightest.
