"Did you ever go to seminary?"
Short answer: no.
Long answer: No, because I went through the conversion process, spent seven weeks at a Hebrew-only ulpan at Middleburg College, and received a master's in Judaic studies (focus on midrashic literature) resulting in a depth of information greater than many likely obtain in seminary.
That leaves me with a question, however, which is: Aside from the social experiment of seminary, what else did I miss out on?
