Ultimas manus : being letters between Mr. John Humphrey, and Mr. Samuel Clark, in reference to the point of justification : written upon the occasion of Mr. Clark's printing his book upon that subject, after Mr. Humfrey's book entituled The righteousness of God, and published for vindication of that doctrine wherein they agree, as found, by shewing the difference of it from that of the Papist, and the mistakes of our common Protestant : in order to an impartial and more full understanding of that great article, by the improvement of that whereto they have attained, or correction of any thing wherein they err, by better judgments : together with animadversions on some late papers between Presbyterian and Independent, in order to reconcile the difference, and fix the Doctrine of Christ's satisfaction.
