A final answer to the editor of Benj. Ben Mordecai's Letters; (and in particular to his eighth letter, called "an inquiry into the opinions of the learned Christians" &c.) in which, The eternal Generation and divine Nature of the Word that was made Flesh and suffered for the Sins of Mankind, is Asserted and Proved, By conclusive Arguments, both from Scripture and Reason; and his vain Objections, and those of all other Unbelievers, Fully Refuted, By the author of "the harmony of the truth."
