An eloquent statement of the argument for the resurrection from the analogies of nature occurs in Tertull. De Resurr. c. xii. That it was not unknown to Cyril, seems probable from the concluding sentence: “And surely if all things rise again for man, for whom they have been provided—but not for man unless for his flesh also—how can the flesh itself perish utterly, for the sake and service of which nothing is allowed to perish.” Tertullian himself was probably indebted, as Bp. Lightfoot suggests, to Clemens. Rom. Epist. ad Corinth. xxiv. Cf. Lactant. Div. Inst. vii. 4.
