Political order before the fall
In the first state also there would have been one political order without the division of empires introduced by sin. The first and sole lord of the circle of the earth was Adam, the second Seth, the third whoever was best among the descendants — and therefore empire was divided, because humans sinned, and divided fields and dominions, and usurped kingship. And the law of nations was introduced through iniquity, as holy Clement teaches, which is retained by permission, not by Gods command, who willed all to live in common, as the same witnesses, and Ambrose, and Chrysostom, and the better fathers. Hence also Solomon says: because of the sins of the land, many are its princes.
For in the beginning the same one would have been king and father and highest priest of the commonwealth and supreme in the whole world, depending on God, as Melchizedek. And therefore Christ recalled all princes under the empire of Himself as one shepherd, when He came to restore that age (Ezekiel 34:23; John 10:16). Nor will wars, famine, heresies, schisms, and plagues cease until all the princes of the earth, brought under one power, have one senate and live in concord. Which will plainly happen when from this warfare and pilgrimage we pass into the homeland of eternal rest and triumph. For the Chiliasts are vain who hope this on the earth of this warfare, and the papal party who violently grasp at it.
Latin
In primo etiam statu unus fuisset ordo politicus sine divisione imperiorum per peccatum introducta. Primus et unus dominus orbis terrarum fuit Adam, secundus Seth, tertius qui optimus ex descendentibus — et propterea divisum est imperium, quia peccaverunt homines, ac diviserunt agros et dominia et regnum usurparunt. Et introductum est ius gentium per iniquitatem, ut docet S. Clemens, quod retinetur ex permissione, non ex imperio Dei, qui omnes vivere in communi voluit, ut idem testatur, et Ambrosius, et Chrysostomus et meliores patres. Unde et Salomon ait: propter peccata terrae, multi principes eius. In principio enim fuisset idem rex et pater et summus sacerdos reipublicae et supremus in toto mundo a Deo dependens, ut Melchisedechus. Proptereaque Christus omnes principes sub sui unius pastoris imperium revocavit, cum ad saeculum illud restituendum venit (Ezech. 34:23; Ioh. 10:16). Nec bella, fames, haereses, schismata, pestes cessabunt, donec omnes principes terrae sub unius potestatem redacti unum senatum habeant, vivantque concordes. Id quod fiet plane, ubi ex hac militia et peregrinatione transibimus in patriam aeternae quietis et triumphi. Frustra enim sunt Chiliastae, qui hoc sperant in terra huius militiae, et pontificii, qui violenter affectant.
