Satan In Heaven

Quadam autem die quum venissent Filii Dei, ut assisterent coram Domino, adfuit inter eos etiam et Satan. Multae sunt curiae, et aliquis Satan semper invenitur in singulis. Est autem, qui est accusator fratrum, et bonorum depravator, occultus omnium adversarius, et quasi anguis inter anguillas, legationes frequentius injunguntur, et forte quod sibi ascribitur ad gloriam, Dei judicio ei imponitur ad laborem. Mittuntur quandoque a Domino boni Angeli, missi in ministerium propter eos, qui haereditatem capiunt salutis. Mittuntur etiam mali angeli ad vexationem malorum, ut fiant, sicut Propheta dicit, immissiones per angelos malos. Mittuntur et ad probationem bonorum, ad virtutis exercitium, ad augmentum gratiae in eis, et ad gloriae incrementum. Qua vero fronte, qua audacia praesumit ille filius superbiae, ille angelus apostata inter Dei filios apparere? Sed quia per superbiam cecidit, superbiendo ascendit. Superbia, inquit, eorum qui te oderunt, ascendit semper. Superbia enim natione coelestis est, in coelo concepit dolorem, et peperit iniquitatem, atque illuc libentius tendit, unde cecidit. Ideo nec apparet Satan inter angelos Dei, ut videat vultum ejus, in quem angeli concupiscunt, cujus faciem angeli semper vident, quia homo Deum non videbit, et vivet. Ablatus est peccator, ne videat gloriam Dei, apparet ergo Satan coram Domino, ut videatur ab eo, quem videre non potest: sicut caecus, qui in radio solis est, et beneficio solis non utitur, et hoc solum videre permittitur, quod sibi reputat ad tormentum; torquetur enim invidia, immoritur angelorum felicitati, et prosperitati fidelium intabescit, juxta illud: Peccator videbit et irascetur, dentibus suis fremet et tabescet.

On a certain day the sons of God had come to stand before the Lord, and Satan was among them. 1 Many are the courts, and there is always some Satan to be found in each one. He who is the accusor of brothers, a depraver of good men, a hidden adversary of all, even like a snake among eels, most frequently joining himself with messangers, and perhaps he ascribes this to himself as some honour, that which by the judgement of God is a toil imposed on him. Whenever good angels are sent forth from the Lord, they are sent to the service of those who seek the inheritance of salvation. But evil angels are sent for the vexation of the wicked, which occur, as the Prophet says, 'through his wicked angels.' 2 And they are sent out for the proving of good men, for the exercise of virtue, for the growth of grace in them, and for an increase of glory. However with what shamelessness, with what audacity, did that son of pride, that apostate angel, presume to appear among the sons of God? Because he fell on account of pride, so in pride he rises. 'The pride of those who hate you,' it is said, 'ever rises up.' 3 Pride in the world is heavenly, in heaven it conceives sorrow and gives birth to iniquity, 4 and thus tends to willfulness, for which reason he fell. Therefore Satan does not appear among the angels of God so that he might see the face of God, on which the angels look, that face on which the angels always look, 5 because a man shall not see God and live. The sinner is cast out lest he see the glory of God; therefore Satan appears before the Lord that he might be seen by Him whom he is not able to see, as a blind man who has gains nothing from the radiance and blessing of the sun. And this alone he is permitted to see: that which he reckons to be a torment, for it is torture on account of envy for him to tarry among the joy of the angels, and the flourishing of the faithful makes him wither, on account of which it says: 'The sinner shall see and be angered, and he shall grind his teeth and wither.' 6 Peter of Blois, Compendium On Job, To Henry II Most Illustrious King Of The English, Chapter I 1 Job 2.1 2 Ps 77.49 3 Ps 73.23 4 Ps 7.15 5 Mt 18.10 6 Ps 111.10
