"How is one to explain the contradiction illustrated by that orator? Is it because Abraham had a prescriptive right to be a great man, so that what he did is great, and when another does the same it is sin, a heinous sin? In that case I do not wish to participate in such thoughtless eulogy. If faith does not make it a holy act to be willing to murder one's son then let the same condemnation be pronounced upon Abraham as upon every other man."
