Acts 1:3

After these points, Celsus proceeds to bring against the Gospel narrative a charge which is not to be lightly passed over, saying that “if Jesus desired to show that his power was really divine, he ought to have appeared to those who had ill-treated him, and to him who had condemned him, and to all men universally.” For it appears to us also to be true, according to the Gospel account, that He was not seen after His resurrection in the same manner as He used formerly to show Himself, publicly, and to all men. But it is recorded in the Acts, that “being seen during forty days,” He expounded to His disciples “the things pertaining to the kingdom of God.” And in the Gospels it is not stated that He was always with them; but that on one occasion He appeared in their midst, after eight days, when the doors were shut, and on another in some similar fashion. …

If, therefore, this prophetess confesses the resurrection, and does not deny the restoration of all things, and distinguishes the godly from the ungodly, it is in vain for them to deny our doctrine. Nay, indeed, they say they can show a resemblance of the resurrection, while they do not themselves believe the things they declare: for they say that there is a bird single in its kind which affords a copious demonstration of the resurrection, which they say is without a mate, and the only one in the creation. …

10. Perhaps you will say to me, When, then, did the Paraclete promised by the Lord come? As regards this, had I nothing else to believe on the subject, I should rather look for the Paraclete as still to come, than allow that He came in Manichæus. But seeing that the advent of the Holy Spirit is narrated with perfect clearness in the Acts of the Apostles, where is the necessity of my so gratuitously running the risk of believing heretics? For in the Acts it is written as follows: "The former treatise have we made, O Theophilus, of all that Jesus began both to do and teach, in the day in which He chose the apostles by the Holy Spirit, and commanded them to preach the gospel. By those to whom He showed Himself alive after His passion by many proofs in the daytime, He was seen forty days, teaching concerning the kingdom of God. …

9. That this number, then, is a sign of that laborious period in which, under the discipline of Christ the King, we have to fight against the devil, is also indicated by the fact that both the law and the prophets solemnized a fast of forty days, that is to say, a humbling of the soul, in the person of Moses and Elias, who fasted each for a space of forty days. And what else does the Gospel narrative shadow forth under the fast of the Lord Himself, during which forty days He was also tempted of the devil, than that condition of temptation which appertains to us through all the space of this age, and which He bore in the flesh which He condescended to take to Himself from our mortality? After the resurrection also, it was His will to remain with His disciples on the earth not longer than forty days, continuing to mingle for that space of time with this life of theirs in the way of human i …

74. Luke next proceeds with his narrative in the following terms: “And as they thus spake, Jesus Himself stood in the midst of them, and saith unto them, Peace be unto you: it is I; be not afraid. But they were terrified and affrighted, and supposed that they had seen a spirit. And He said unto them, Why are ye troubled? and why do thoughts arise in your hearts? Behold my hands and my feet, that it is I myself: handle me and see; for a spirit hath not flesh and bones, as ye see me have. …

84. At the same time, all is not recorded, as John plainly declares. For He had frequent intercourse with His disciples during the forty days which preceded His ascension into heaven. He had not, however, showed Himself to them throughout all these forty days without interruption. For John tells us, that after the first day of His resurrection-life, there elapsed other eight days, at the end of which space He appeared to them again. The appearance which is identified [in John] as the third, namely, the one by the sea of Tiberias, may perhaps have taken place on an immediately succeeding day; for there is nothing antagonistic to that. And then He showed Himself when it seemed the proper time to Him, as He had appointed with them (which appointment had also been conveyed in the previous prophetic announcement) to go before them into Galilee. …

32. Now, in the generations which Matthew enumerates, the predominant number is forty. For it is a custom of the Holy Scriptures, not to reckon what is over and above certain round numbers. For thus it is said to be four hundred years, after which the people of Israel went out of Egypt, whereas it is four hundred and thirty. And so here the one generation, which exceeds the fortieth, does not take away the predominance of that number. Now this number signifies the life wherein we labour in this world, as long as we are absent from the Lord, during which the temporal dispensation of the preaching of the truth is necessary. For the number ten, by which the perfection of blessedness is signified, multiplied four times, because of the fourfold divisions of the seasons, and the fourfold divisions of the world, will make the number forty. …

13. By all means there is a sense, a true and strong sense, if somehow we can grasp it, in which “the Father judgeth not any man, but hath given all judgment to the Son.” For this is said because none will appear to men in the judgment but the Son. The Father will be hidden, the Son will be manifest. In what will the Son be manifest? In the form in which He ascended. For in the form of God He was hidden with the Father; in the form of a servant, manifest to men. Not therefore “the Father judgeth any man, but all judgment hath He given to the Son:” only the manifest judgment, in which manifest judgment the Son will judge, since the same will appear to them that are to be judged. The Scripture shows us more clearly that it is the Son that will appear. …

13. It may be also understood in this way: “The poor ye will have always with you, but me ye will not have always.” The good may take it also as addressed to themselves, but not so as to be any source of anxiety; for He was speaking of His bodily presence. For in respect of His majesty, His providence, His ineffable and invisible grace, His own words are fulfilled, “Lo, I am with you alway, even to the end of the world.” But in respect of the flesh He assumed as the Word, in respect of that which He was as the son of the Virgin, of that wherein He was seized by the Jews, nailed to the tree, let down from the cross, enveloped in a shroud, laid in the sepulchre, and manifested in His resurrection, “ye will not have Him always.” And why? Because in respect of His bodily presence He associated for forty days with His disciples, and then, having brought them forth for the purpose of beholding …

1. It becomes us, dearly beloved, to keep in view the orderly connection of our Lord’s words. For after having previously said, but subsequently to Judas’ departure, and his separation from even the outward communion of the saints, “Now is the Son of man glorified, and God is glorified in Him;”, whether He said so as pointing to His future kingdom, when the wicked shall be separated from the good, or that His resurrection was then to take place, that is, was not to be delayed, like ours, till the end of the world; and having then added, “If God is glorified in Him, God shall also glorify Him in Himself, and shall straightway glorify Him,” whereby without any ambiguity He testified to the immediate fulfillment of His own resurrection; He proceeded to say, “Little children, yet a little while I am with you.” To keep them, therefore, from thinking that God was to glorify Him in such a way t …

6. On this point, also, in reference to what has been said above, I think we may get a still better understanding of the words, “A little while, and ye shall no more see me: and again a little while, and ye shall see me.” For the whole of that space over which the present dispensation extends, is but a little while; and hence this same evangelist says in his epistle, “It is the last hour.” For in this sense also He added, “Because I go to the Father,” which is to be referred to the preceding clause, where He saith, “A little while, and ye shall no more see me;” and not to the subsequent, where He saith, “And again a little while, and ye shall see me.” For by His going to the Father, He was to bring it about that they should not see Him. …

12. “Forty years long was I very near unto this generation, and said, It is a people that do always err in their hearts; for they have not known My ways” ( ver. 10 ). The forty years have the same meaning as the word “always.” For that number forty indicates the fulness of ages, as if the ages were perfected in this number. Hence our Lord fasted forty days, forty days He was tempted in the desert, and forty days He was with His disciples after His resurrection. On the first forty days He showed us temptation, on the latter forty days consolation: since beyond doubt when we are tempted we are consoled. For His body, that is, the Church, must needs suffer temptations in this world: but that Comforter, who said, “Lo, I am with you alway, even unto the end of the world,” is not wanting. …
