Heaven And The Church

Coelum spiritualiter Ecclesia est, quae in hujus vitae nocte sanctorum virtutibus, quasi claritate siderum, fulget. Pluraliter autem colei nomine sancti omnes, vel angelis intelligeuntur. Siquidem per coelos etiam prophetas et apostolos accipere debemus. De quibus scriptum est: Coeli enarrent gloriam Dei; utique quod ipsi adventum et mortem, ipsi quoque resurrectione Christi et gloriam mundo annuntiaverunt. Sanctus Isidorus Hispalensis, De Natura Rerum, Caput XII Source: Migne PL 83.981b-983a

Spiritually heaven is the Church, which in the night of this life shines with the virtues of the saints as with the brightness of the stars. But in the plural all the saints and angels are understood by the name of heaven, and likewise we should take the heavens as the Prophets and Apostles, of whom it is written, 'The heavens tell of the glory of God,' 1 since these announced to the world the coming and the death and the resurrection and the glory of Christ. Saint Isidore of Seville, On The Nature Of Things, Chap 12 1 Ps 18.2
