Ascent And Jerusalem

Pervenit itaque vir iste ad tertium ascensionis gradum, id est in desiderium coelesis Hieusalem ad quam spe ascendere se gaudebat, licet adhuc hic in terrenis laboraret; ideo ait: Laetatus sum in his quae dicta sunt mihi, in domum Domini ibimus. Laetatus sum in prophetis, laetatus sum in apostolis, imo et in omnibus sanctis, qui mihi dicunt: In domum Domini ibimus; qui dicunt, currite, festinate in domum Domini, id est, in coelestem Hierusalem properate. Stantes erant pedes nostri in atriis tuis, Hierusalem. Stantes, id est permanentes; pedes nostri, id est, praemia bonorum operum: in atriis tuis, Hierusalem, id est, in coelestibus habitationibus. Atria dicit plurali numero, ipsa Veritate dicente: In domo Patris mei multae sunt mansiones. Quasi iste amator quaerat, quae sit ista Hierusalem, dictum est ei: Hierusalem quae aedificatur ut civitas, cujus participatio ejus in idipsum. Hierusalem, quae ex vivis lapidibus construitur; quae aedificatur ut civitas, non terreni regis, sed coelestis; non temporalis, sed aeterna Hierusalem. Cujus participatio ejus in idipsum. Quod semper idem est, idipsum est. Quis est, qui semper idem est, nisi Deus, qui dixit: Ego sum qui sum; qui descendit, ut ascenderemus; qui participavit nostrae mortalitati,nam Verbum caro factum est et habitavit in nobis, ut participare possemus suae aeternitati. Nam de plentitudine ejus omnes accepimus. Qui sunt autem qui ascensuri sunt in istam civitatem, ad istem participationem, consequenter exposuit, dicens, Illuc enim ascenderunt tribus, tribus Domini, testimonium Israel ad confitendum nomini Domini. Non tribus terrae, de quibus dicitur: Et plangent eum omnes tribus terrae, sed tribus Domini, quae duodecim apostoli judicaturi erunt, secernetnes eos ab illis quae sunt tribus diaboli: harum enim testimonium in Israel, id est, in illis qui vident Deum. Ad quid ascendunt? Ad confitendum nomini tuo, Domine: sicut dictum est: Confessio et pulchritudo in conspectu ejus. Alcuinus, Expositio in Psalmos Graduales, Psalmus CXXI Source: Migne PL 100.622c-623a

He comes to the third step of the ascent, that is, to the desire for the heavenly Jerusalem, in which hope of ascending to it he rejoices in himself, though he yet labours on the earth, and therefore he says, I rejoiced in those things that were said to me, we shall go into the house of the Lord. 1 I rejoiced in the prophets, I rejoiced in the apostles, and in all the saints, who say to me 'we shall go into the house of the Lord,' who say, run, hurry into the house of the Lord, that is, make haste to go into the heavenly Jerusalem. Our feet were standing in your courts, O Jerusalem. Standing, that is established, our feet, that is, in the rewards of good works, in your courts, O Jerusalem, that is, in the heavenly dwellings. Courts is in the plural, with the Truth Himself saying, 'In the house of my father there are many mansions.' 2 Then as if this lover asked what this Jerusalem might be, it was said to him, Jerusalem which is built up like a city closely fitted together, whose fellowship is united. Jerusalem, which is built up of living stones, 3 which is constructed as a city, not as some terrestrial kingdom, but a heavenly one; not a temporal but a heavenly Jerusalem. Because it is always the same, it is united. What is it that is always the same unless God, who says, 'I am who I am,' 4 who descended that we might ascend, who partook of our mortality, for 'the Word was made flesh and dwelt among us,' so that we might be able to participate in His eternity? For from His fullness we have received everything. 5 And who they are who ascend into this city, to this participation, he then explains, saying, From there the tribes went up, the tribes of the Lord, witness of Israel, to take joy in the name of the Lord. Not the tribes of the world, concerning whom it is said, 'And all the tribes of the earth cried out to Him,' but the tribes of the Lord, of whom the twelve Apostles will be the judges, separating them from those who are of the tribes of the devil. 6 For from these is the witness of Israel, that is, in those who see God. And to what do they ascend? To taking joy in your name, O Lord, as it has been said. 'Confession and beauty before Him.' 7 Alcuin of York, Commentary on the Gradual Psalms, from Psalm 121 1 Ps 121.1 2 Jn 14.2 3 1 Pet 2.5 4 Exod 3.14 5 Jn 1.14,16 6 Apoc 1.7, Mt 19.28 7 Ps 95.6
