Pope St. Clement I: God Has Pledged that We Will Rise

Let us consider, beloved, how the Lord continually proves to us that there shall be a future resurrection, of which He has rendered the Lord Jesus Christ the first-fruits by raising Him from the dead. Let us contemplate, beloved, the resurrection which is at all times taking place. Day and night declare to us a resurrection. The night sinks to sleep, and the day arises; the day [again] departs, and the night comes on. Let us behold the fruits [of the earth], how the sowing of grain takes place. The sower goes forth, and casts it into the ground, and the seed being thus scattered, though dry and naked when it fell upon the earth, is gradually dissolved. Then out of its dissolution the mighty power of the providence of the Lord raises it up again, and from one seed many arise and bring forth fruit. . . .

Do we then deem it any great and wonderful thing for the Maker of all things to raise up again those that have piously served Him in the assurance of a good faith, when even by a bird [referring to the legend of the phoenix, omitted above] He shows us the mightiness of His power to fulfil His promise? For the Scripture saith in a certain place, "Thou shalt raise me up, and I shall confess unto Thee"; and again, "I laid me down, and slept"; "I awaked, because Thou art with me; " and again, Job says, "Thou shalt raise up this flesh of mine, which has suffered all these things."

Having then this hope, let our souls be bound to Him who is faithful in His promises, and just in His judgments. He who has commanded us not to lie, shall much more Himself not lie; for nothing is impossible with God, except to lie. Let His faith therefore be stirred up again within us, and let us consider that all things are nigh unto Him. By the word of His might He established all things, and by His word He can overthrow them. "Who shall say unto Him, What hast thou done? or, Who shall resist the power of His strength?" When, and as He pleases, He will do all things, and none of the things determined by Him shall pass away. All things are open before Him, and nothing can be hidden from His counsel. "The heavens declare the glory of God, and the firmament showeth His handy-work. Day unto day uttereth speech, and night unto night showeth knowledge. And there are no words or speeches of which the voices are not heard."
