Expulsion And Excommunication

Et nunc, inquit Deus, ne aliquando extendat manum, et sumat de ligno vitae, et edat, et vivat in aeternum. Et dimisit illum Dominus Deus de paradiso voluptatis operari terram, ex qua sumptus est. Superiora verba Dei sunt; hoc autem factum propter ipsa verba secutum est. Alienatus enim a vita, non solum quam fuerat, si praeceptum servasset, cum Angelis accepturus, sed ab illa etiam quam ducebat in paradiso, felici quondam corporis statu, separari utique debuit a ligno vitae: sive quod ex ipso illi subsisteret felix ille ipse status corporis, ex re visibili, virtute invisibili, sive quod in eo esset et sacramentum visibile invisibilis sapientiae; alienandus inde utique fuerat, vel iam moriturus, vel etiam tamquam excommunicatus: sicut etiam in hoc paradiso, id est Ecclesia, solent a Sacramentis altaris visibilibus homines disciplina ecclesiastica removeri. Sanctus Augustinus Hipponensi, De Genesi Ad Litteram, Liber XI, Caput XL Source: Migne PL 34.451

And now said God: 'Lest at some time he reach out his hand and take from the tree of life and eat and live forever. And God sent him from the paradise of delight to work the earth from which he came.' 1 The words of God above are that this was done on account of what had happened. For he was estranged from life, not only from what he would be, if he had kept the commandment, that he would be received with angels, but even from how he was in paradise, that once happy state of body, and thus he was separated from the tree of life, whether because he subsisted on it for his happy state of body, from a thing visible, virtue invisible, or that by it was the visible sacrament of invisible wisdom; thus he was estranged, as now already dead, or as one excommunicated, as even in this paradise which is the Church, they are accustomed by ecclesiastical discipline to remove men from the visible sacraments of the altar.   Saint Augustine of Hippo, On Genesis To The Letter, Book 11, Chap 40 1 Gen 3.22
