Things Of The Father And Of The Son

Ego pro eis rogo, non pro mundo rogo, sed pro his, quos dedisti mihi, quia tui sunt: et mea omnia tua sunt, et tua mea sunt: et clarificatus sum in eis. Qui tui sunt. Neque enim quia Pater eos Filio dedit, amisit ipse quos dedit, cum adhuc Filius sequatur ac dicat: Et mea omnia tua sunt, et tua mea. Ubi satis apparet quomodo unigeniti Filii sint omnia quae sunt Patris; per hoc utique quod etiam ipse Deus est, et de Patre Patri natus aequalis. Hoc enim dictum est de sancta et rationabili creatura, quam eligit Deus, et quae subdita est Patri et Filio, et aequaliter est Patris et Filii. Haec ergo cum sit Dei Patris, non simul esset et Filii, nisi Patri Filius aequlais. Nec fas est ut sancti, de quibus haec locutus est, cujusquam sint, nisi ejus a quo creati et santificati sunt. Ergo cum et Patris et Filii sunt, aequales esse demonstrant, quorum aequaliter sunt. Et clarificatus sum, inquit, in eis. Nunc suam clarificationem tanquam facta sit dicit, cum adhuc esset futura. 'Clarificatus sum in eis,' id est, per eorum praedicationem clarificatus sum in toto mundo. Et quia praedestinatum est ut fieret, certum voluit esse quod futurum erat. Ideo praeteriti temporis verbo usus est. Alcuinus, Commentariorum in Joannem, Lib VII, XXXIX Source: Migne PL 100.963c-d

For them I pray, not for the world, but for these whom you have given to me. For they are yours. All mine is yours, and yours is mine, and I am glorified in them. 1 'They who are yours.' For it is not that the Father gives them to the Son, and He is deprived of those He gives, since the Son continues and says: 'All mine is yours, and yours is mine.' Where it appears abundantly how everything of the only begotten Son is of the Father, by which indeed He is God, and being from the Father is equal to the Father. And this is said regarding holy and rational creatures, whom God chooses, and which are subject to the Father and the Son, and equally to the Father and the Son. These things then which are of God the Father would not be of the Son, unless the Son is equal to the Father. Is it not right that holy men, concerning which this is spoken, belong to anyone but Him by whom they are created and sanctified. Therefore, when they are of the Father and of the Son, they are revealed as equal, of whom the belongings are equal. 'And I am glorified.' He says, 'in them.' Now He speaks of His glorification as something done, when yet it is in the future. 'I am glorified in them,' that is, when by their preaching I am glorified in the whole world. And because it is predestined that it should be, certainly He wished that it was in the future. Therefore He used the past tense. 2 Alcuin of York, Commentary On The Gospel of Saint John, Book 7, Chapter 39 1  Jn 17.9-10 2 Adapted from Augustine's Tractate 107.2 on The Gospel of St John
