"An Examination of the Testimony of the Four Evangelists, by the Rules of Evidence Administered in Courts of Justice" by Simon Greenleaf is a Christian apologetic work published in 1846. A Harvard Law School professor applies legal standards used in courtrooms to evaluate the Gospel accounts of Jesus's death and resurrection. Greenleaf treats the evangelists as witnesses in a trial, examining their credibility through tests of honesty, ability, consistency, and circumstantial evidence. He concludes that the Gospel writers qualify as reliable witnesses under the same rigorous cross-examination applied in human tribunals.
