Thanks for all your prayers! I wrote for about 90 min, felt comfortable, and handed in the exam. It was two questions, one about "can it be said that canonical Christianity was established in the late second century?" referring to the array of sects vying for the title "The Orthodox" and the other was a question about St Justin Martyr's theory of the logos spermatikos. Actually these are the two I chose, as there were options which I greatly appreciated.
