The Blindness of the Sodomites

Sodmitae ergo angelos conantur violenter irrumpere, cum homines ad Deum tentant per sacri ordinis officia propinquare. Sed hi profecto caecitate percutiuntur, quia justo Dei judicio in tenebras interiores cadunt; ita ut nec ostium invenire praevaleant, quia a Deo peccando divisi, unde ad eum revertuntur ignorant. Qui enim per humilitatis, sed per arrogantiae, et tumoris anfractus ad Deum accedere gestiunt, patet profecto, quia unde ingressionis aditus pateat non agnoscunt; vel etiam quia ostium Christus est, sicut ipse dicit: 'Ego sum ostium.' Qui Christum peccatis exigentibus amittunt, quasi intrare coelestium civium habitaculum non possint, ostium non invenient.In reprobum ergo sensum traditi sunt, quia dum reatus sui pondus in propriae mentis statera non trutinant, gravissimam plumbi massam, poenarum inanium levitatem putant. Quod ergo illic dicitut: Percusserunt eos, qui foris erant caecitate. hoc Apostulus manifeste declarat, cum dicit, 'Tradidit eos Deus in reprobum sensum,' et quod illic subjungitur, 'Ut ostium invenitre non possent. Sanctus Petrus Damianus, Liber Gomorrhianus

Therefore as the Sodomites try to break in violently upon the angels, so it may be with men who attempt to draw near to sacred office. But these are certainly struck with blindness by the just judgement of God and they fall into interior darkness so they are not able to discover the door, because they are separated from God by sin, whence they are ignorant where to turn for it. Indeed those who not though humility but by arrogance and conceited twisting ways try to come near God do not know the way of access, though it certainly be obtainable, or even that Christ is the door, for as he said, ' I am the door.'  By pressing sins they have lost Christ and they are not able to enter a dwelling of the celestial city, for they have not found the entrance. Thus they are given to a depraved mind because while guilt weighs on their mind they dare not weigh the scales with such a large mass of heavy lead and they think lightly of empty punishments. Whence it is said, 'They struck those who were outside with blindness.' This also the Apostle declares openly when he says, ' God has given them over to a depraved mind' and by this they are ruled so that the they are not able to find the door. Saint Peter Damian.
