Greenleaf then builds a cumulative case by claiming to cross-examine the oral testimony of the evangelists in their accounts of the death and resurrection of Jesus. Greenleaf develops his case on the basis of the following tests:"The credit due to the testimony of witnesses depends upon, firstly, their honesty; secondly, their ability; thirdly, their number and the consistency of their testimony; fourthly, the conformity of their testimony with experience; and fifthly, the coincidence of their testimony with collateral circumstances" (p. 28).
