The thief comes not, but to steal, and to kill, and to destroy: I am come that they might have life, and that they might have it more abundantly.

Cyril of Alexandria
AD 444
While Our Saviour Christ was saying He Himself was the Door, and teaching that it was His both to admit those whom He would and to keep outside him who is unfit and quite useless for shepherd's work; and moreover, in addition to this, had denounced as thieves and robbers those who were self-appointed to an honour not given them from above; the wretched Pharisees again were taking counsel, deliberating Who this Man was that shewed so much boldness, and considering whether He ought not Himself perhaps to be numbered among those whose coming He reproved: for they thought that He too was a false shepherd and a false teacher, as merely self-consecrated by His own determination; not that being God He had been made Man, according to the ancient declaration of the inspired Scripture. And it is indeed probable that even when they had gathered a true knowledge of Him, they rejected it as something which was intolerable to their unbelief, and refused to consider anything which was not in harmony with their own pleasure and their own dear delight; and this was to be leaders of the people and to be spoken of accordingly. When therefore He knew that such were their thoughts and that they so whispered one to another, He did not wait for them to express these ideas more openly, but answered them as was fitting, and declares that the question ought to be decided by testing their actions, as to who was the shepherd, and who was the thief; saying that it would be by no means difficult to thus discriminate, if any one would consider the object and behaviour of each. For the thief cometh, He says, for the destruction of the sheep, since the desire of taking plunder undoubtedly leads to this issue; but the really good shepherd will come without bringing any harm into the sheepfold, but rather will work for their advantage, and whatever he may understand to be for their greatest good, that he will zealously labour for.
Therefore let us now pass as from another image to the truer matter to which the force of the words applies, and let us again consider the Pharisees, how they at that time were acting like false shepherds and false teachers towards such as were, cheated by them; and then let us consider what Christ came to give, and what happiness He came to bring us. They certainly never scrupled to speak falsely, and feigning themselves to be sent from God, they prophesied (according to that which is written) out of their own hearts, and not out of the mouth of the Lord; and besides these, that Theudas also, and Judas of Galilee, drawing away people after them, were destroyed together with those who had been led to join them: but Our Lord Jesus Christ came to bestow upon us eternal life, out of the love which He had towards us. And their aims being so opposite, and the manner of their coming so different, how can it be explained except that their dispositions and offices were of opposite character? Therefore by the test of their behaviour in office we ought to discern. He says, on the one hand what they were, and on the other what He was. For thus it was possible perhaps to persuade the rulers not to think unreasonably of Him any longer by supposing Him to be one of the false shepherds, or one of those who climb up some other way into the sheepfold: but that rather Christ, the Door and the Porter and the Shepherd, had come, not only that the sheep may have life, saith He, but also something more; for besides the restoration to life of those who believe in Him, there is also the certain hope of being blessed with all good things. And probably the word more refers also to this life, meaning what is more abundant or more honourable, and implying the most perfect participation of the Spirit, although very secretly. For the restoration to life is common to both saints and sinners, to both Greeks and Jews, as well as ourselves, for: The dead shall arise, and they that are in the tombs shall awake, and they that are in the earth shall rejoice, according to the sure promise of the Saviour. But the participation of the Holy Spirit is not thus common to all, being the more than life, as it were something beyond that which is common to all; and will be bestowed only upon those who are justified by faith in Christ: and the Divine Paul also will prove this to us, saying: Behold, I tell you a mystery: We shall all sleep, hut we-shall not all be changed, in a moment, in the twinkling of an eye, at the last trump: for the trumpet shall sound, and the dead shall be raised incorruptible, and we shall be changed. For indeed all shall rise from the dead, because this is granted to all nature, through the grace of the Resurrection; and in One, that is, Christ, Who was the first and foremost to break down the dominion of death and attain eternal life, the common lot of humanity was changed and made incorruptible, even as also in one, that is, the first Adam, it was condemned to death and corruption. But there will be at that time an important difference among those who are raised, and very widely distinct will be their destiny. For those who have gone to their rest with faith in Christ, and who have received the earnest of the Spirit in the appointed time of their bodily life, will obtain the most perfect grace, and will be changed to the glory which shall be given from God. But those who have not believed the Son, and have deemed such an excellent reward of no account, shall be once more condemned by His voice, and, sharing with the rest in nothing save in the restoration to life, shall pay the penalty of such prolonged unbelief. For they shall depart down into Hades to be punished, and shall feel unavailing remorse. For, saith He, there shall be the weeping and gnashing of teeth.
