Vain Cities Of God

Dolosa autem doctinae est haereticorum, sub nomine Dei blasphema, sub praetextu religionis impia, sub veritatis specie fallex: quorum in animo et cogitatione solum contentionis studium persistit. Nihil ad salutem hominum laborant, nihil ad spem acquirunt, nihil pacificum cogitant, ut omnis his in contentionibus labor sit, et pugnam meditentur. isti infelices animas exstinguunt, et in vanum ecclesias sibi congregant: quas civitates Dei, secundum propheticam evangelicamque consuetudienm, nuncupari frequens et plurima auctoritas est. Hoc ergo significatur his dictis: Viri sanguinum declinate a me. Quia contentiones in cogitatione, accipient in vanum civitates suas.Viri sanguinum sunt, propter deperditarum animarum reatum: declinare jubentur, quia contentiones in cogitatione sunt. Hi in vanum civitates Dei accipiunt, infructuosarum ecclesiarum coetus per schismatum dissidia reddentes. Sanctus Hilarius Pictaviensis,Tractatus super Psalmos, Tractatus in Psalmum CXXXVIII Source: Migne PL 9.815

Grievous are the teaching of heretics, blasphemy beneath the name of God, impiety beneath the pretext of religion, a lie beneath the appearance of truth, whose soul's only desire is to persist in contention of thought. They do not labour for the salvation of men, nor do they acquire hope, nor do they consider peace, but all their labour is in dispute and all their thoughts of strife. They extinguish unfortunate souls, and they gather their churches in vain, which are the cities of God according to the prophetic and evangelical custom, frequently to be called and great is  their power. And this is signified in these words: 'Men of blood begone from me,' 1 and 'Because they are contending in their thought they will receive their cities in vain.' 2 Men of blood they are on account of the guilt of their ruin of souls, and they are commanded to begone because they are contentious in thought. In vain they receive their cities of God, the dissidence of schism producing a gathering of fruitless churches. Saint Hilary of Poitiers, Homilies on the Psalms, from Psalm 138 1 Ps 138. 19 2 Ps 138.20
