Even Years: St. Irenaeus, Treatise against heresies, Book 4, ch. 20, #4-5

Εἷς οὖν ὁ Θεός, ὁ Λογῳ καὶ Σοφίᾳ ποιήσας καὶ ἁρμόσας τὰ πάντα	There is one God, who by his Word and Wisdom made and ordered all things.
Ἔστι δὲ οὗτος ὁ Λόγος αὐτοῦ ὁ Κύριος ἡμῶν Ἰησοῦς Χριστός, ὁ ἐν ἐσχάτοις καιροῖς ἄνθρωπος ἐν ἀνθρώποις γενόμενος, ἵνα τὸ τέλος συνάψῃ τῇ ἀρχῇ, τουτέστιν ἄνθρωπον Θεῷ.	His Word is our Lord Jesus Christ who in these last times became man among men, that he might unite the end with the beginning, that is, Man with God.
Καὶ διὰ τοῦτο οἱ προφῆται, παρὰ τοῦ αὐτοῦ Λόγου τὸ προφητικὸν λαβόντες χάρισμα, προεκήρυξαν αὐτοῦ τὴν ἔνσαρκον παρουσίαν, δι᾿ ἧς ἡ σύγκρασις καὶ κοινωνία Θεοῦ τε καὶ ἀνθρώπου κατὰ τὴν εὐδοκίαν τοῦ Πατροός ἐγένετο, ἀπ᾿ ἀρχῆς προμηνύσαντος τοῦ Λόγου ὅτι ὀφθήσεται ὁ Θεὸς τοῖς ἀνθρώποις καὶ συναναστραφῆσεται αὐτοῦς ἐπὶ τῆς γὴς καὶ συνομιλήσεται καὶ συμπαρέσται τῷ ἰδιῳ πλάσματι, σῴζων αὐτὸ καὶ χωρούμενος ὑπ᾿ ἀυτοῦ καὶ ῥυόμενος ἡμᾶς ἐκ χειρῶν πάντων τῶν μισούντων ἡμᾶς, τουτέστι παντὸς παραβατικοῦ πνεύματος, καὶ διδοὺς λατρεύειν αὐτῇ ἐν ὁσιότητι καὶ δικαιοσύνῃ πάσας τὰς ἡμέρας ἡμῶν, ἵνα συμπλακεὶς ὁ ἄνθρωπος τῷ Πνεύματι τοῦ Θεοῦ εἰς δόξαν χωρῇ Πατρός	Therefore the prophets who received from this same Word their prophetic gift, proclaimed his advent in the flesh, by which was effected the mingling and uniting of God and man according to the Father's pleasure. For the Word of God foretold from the beginning that God would be seen by men and would live with them on earth and converse with them; that he would be present with his creatures to bring salvation to them and to be perceived by them; that he would free us from the hands of those who hate us, that is, from the whole spirit of transgression; and would make us serve him all our days in holiness and righteousness; that man, taking to himself the Spirit of God, would pass to the glory of the Father.
Προεμήνυον οὖν οἱ προφῆται ὅτι ὁραθήσεται ὁ Θεὸς ὑπὸ τῶν ἀνθρώπων, ὁς καὶ ὁ Κύριός φησιν· Μακάριοι οἱ καθαροὶ τῇ καρδίᾳ, ὅτι αὐτοὶ τὸν Θεὸν ὄψονται.	The prophets therefore indicated beforehand that God would be seen by men; as the Lord also says, Blessed are the pure in heart, for they shall see God.
Ἀλλὰ κατὰ μὲν τὸ μέγεθος αὐτοῦ καὶ τὴν ἀνεξήγητον δόξαν οὐδεὶς ὄψεται τὸν Θεὸν καὶ ζήσεται, ἀχώρητος γὰρ ὁ Πατήρ· κατὰ δὲ τὴν ἀγάπην καὶ τὴν φιλανθρωπίαν καὶ τὸ δύνασθαι αὐτὸν πάντα, καὶ τοῦτο ἐνδίδωσι τοῖς ἀγαπῶσιν αὐτόν, τὸ ὁρᾶν Θεόν, ὅ δὴ καὶ πορεφήτευον οἱ προφῆται, διότι τὰ ἀδύνατα παρὰ ἀνθωώποις δυνατὰ παρα τῷ Θεῷ.	I grant that in respect of his greatness and marvellous glory, no man shall see God and live, for the Father is incomprehensible. But in respect of his love and kindly mercy, and of his infinite power, he grants even this to such as love him, I mean, to see God, as the prophets also foretold. Because the things which are impossible with men are possible with God.
Καὶ γὰρ ὁ μὲν ἄνθρωπος ἀφ᾿ ἑαυτοῦ οὐκ ὄψεται Θεόν· ὁ δὲ Θεὸς βουλόμενος ὀφθήσεται ἀνθρώποις, οἷς βούλεται καὶ ὁπότε βούλεται καὶ καθὼς βούλεται. Δυνατὸς γὰρ ἐν πᾶσιν ὁ Θεός, ὀφθεὶς μὲν τότε διὰ τοῦ Πνεύματος προφητικῶς, βλεπόμενος δὲ καὶ διὰ τοῦ Υἱοῦ υἱοποιήτως, ὀφθησόμενος δὲ καὶ ἐν τῇ βασιλείᾳ τῶν οὐρανῶν πατρικῶς, τοῦ μὲν Πνεῦματος προκατασκευάζοντος τὸν ἄνθρωπον εἰς τὸν Υἱὸν τοῦ Θεοῦ, τοῦ δὲ Υἱοῦ προσάγοντος τῷ Πατρί, τοῦ δὲ Πατρὸς ἀφθαρσίαν χαριζομένου καὶ αἰώνιον ζωήν, ἥτις ἐκ τοῦ βλέπειν τὸν Θεὸν περιγίνεται τοῖς ὁρῶσιν αὐτόν.	Man does not see God by his own powers; but God of his own will appears to men, to whom he wills, and when he wills, and as he wills. For God can do all things: he was seen in former times prophetically through the Spirit, he is seen in the Son by adoption, and he will be seen in the kingdom of heaven as Father. The Spirit prepares man for the Son of God, the Son brings him to the Father, and the Father bestows on him incorruptibility for eternal life, which comes to everyone from his beholding God.
Ὥσπερ γὰρ οἱ βλέποντες τὸ φῶς ἐντός εἰσι τοῦ φωτὸς καὶ τῆς λαμπρότητος αὐτοῦ μετέχουσιν, οὕτως οἱ βλέποντες τὸν Θεὸν ἐντός εἰσι τοῦ Θεοῦ, μετέχοντες αὐτοῦ τῆς λαμπρότητος· ζωοποιοῦσα δὲ ἡ τοῦ Θεοῦ λαμπρότης· ζωῆς οὖν μεθέξουσιν οἱ ὁρῶντες Θεόν.	As those who see the light are in the light, and partake of its splendour, so those who see God are in God, partaking of his splendour. But God's splendour gives life; those therefore who see God will partake of life.

Odd Years: Hilary of Poitier, On Psalm 60, 5-6 (CSEL 22, 205-207)

Dedisti hereditatem timentibus nomen tuum. dies super dies regis adicies, annos eius usque in dies generationis et generationis. permanet in aeternum in conspectu Dei.

Haec enim hereditas sancti est, uita et incorruptio et regnum et coaeterna Deo habitatio. Non Israel tantum haec hereditas scripta est, sed timentibus Dei nomen. Dies enim aeterni sunt regis, siue quia sancti, qui peccati serui non erunt, reges sunt secundum illud apostoli: Iam sine nobis regnastis et utinam regnaretis, ut et nos uobis cum conregnaremus, siue quia hic idem etiam rex sit propheta, siue quia aeternum regnum consedentem a dextris oportet regnare, donec ponat inimicos suos sub pedibus suis, non ut rex ipse tum non sit, sed cum tradiderit regnum Deo Patri, conregnabit his ipsis qui reges sunt.

Ex quo mihi uidetur haec nunc ratio seruata, ut usque in dies generationis et generationis adicerentur super dies dierum anni eius, in conspectu autem Dei maneat in aeternum, ut tempus illud, quo eum regnare, donec inimicos suos sub pedibus suis ponat, oportet a generatione usque in generationem sit comprehensum, quia generationem hanc spiritalis natiuitatis generatio ex mortuis consequetur, aeternitatis autem suae exceptio, dum in aeternum in conspectu Dei est, praedicetur. Est autem ipse primogenitus ex mortuis.

Sed huius regenerationis Dominus ad apostolos ita meminit: Amen dico uobis, quod uos, qui secuti estis me, in regeneratione, cum sederit filius hominis in sede maiestatis suae, et uos sedebitis super duodecim thronos iudicantes duodecim tribus Israel. Huius igitur generationis tempus ostendit et usque in hanc super dies dierum anni regis augentur. Ceterum ipse in conspectu Dei manebit aeternus, iam omnibus quos redemit in reges caelorum et coheredes aeternitatis adsumptis, tradens eos regnum Deo Patri.

Et quia comparticipes et concorporales et conformes eius effecti sint iam in his, nec corruptione nec morte dominante, cum in omnem plenitudinem Dei repleantur, subiecit spiritus prophetiae: Misericordiam et veritatem eivs qvis reqviret eorvm? Non inopes iam misericordiae ueritatis que eius hae scilicet generationes erunt, quas in se ex mortuis regenerauit ad uitam quae que in spe gloriae Dei manserint, tum cum in regnum traditae Deo Patri suscipientur in reges, consummata in omnes eius misericordia ac ueritate, per quem redemptas se gratulentur ad uitam sit que omnibus adcessus ad Patrem. Post quod nihil misericordiae ac ueritatis requiratur a Domino, cum in Dei plenitudinem impleantur.
