Increased Rewards And Punishments

Valde insensates ostendebant presbyteri eos, qui ex his quae acciderunt his, qui olim Deo obtemperabant, tentant alterum Patrem introducere; e contrario opponentes, quanta Dominus ad salvandos eos, qui receperunt eum, veniens fecisset, miserans eorum; tacentes autem de judicio ejus, et quaecunque provenient his, qui audierunt sermones ejus, et non fecerunt, et quoniam expediebat eis, si non essent nati, et quoniam tolerabilius Sodmae et Gomorrhae erit in judicio, quam civitati illi quae non recepit sermones discipulorum ejus. Quemadmodum enim in novo testamento, fides hominum aucta est, additamentum accipiens Filium Dei, ut et homo fieret particeps Dei; ita et diligentia conversationis aucta est, cum non solum a malis operibus abstinere jubemur, sed ab ipsis cogitationibus, et otiosis dictionibus et sermonibus vacuis, et verbis scurrilibus: sic et poena eorum, qui non credunt Verbo Dei, et contemnunt ejus adventum, et convertuntur retrorsum, adampliata est; non solum temporalis, sed et aeterna facta. Quibuscunque enim dixerit Dominus: Discedite a me, maledicti, in ignem perpetuum; isti erunt semper damnati; et quibuscunque dixerit: Venite, benedicti Patris mei, percipite haereditatem regni, quod praeparatum est vobis in sempiternum; hi semper percipiunt regnum, et proficiunt. Sanctus Ireneaus Lugdunensis, Adversus Haereses, Lib IV Caput XXVIII Source: Migne PG 7.1061c-1062b

As men utterly lacking in sense the elders showed those who from what befell those who once obeyed God attempt to introduce another Father, opposing them with the many things the Lord did to save those who received Him, having mercy on them, all while they are silent about His judgment and those things which will come to those who have heard His words but not done them, and that it were better for them if they had not been born, 1 and that it shall be more tolerable for Sodom and Gomorrah in judgment than those of that city which did not receive the words of His disciples. 2 For as in the New Testament the faith of men is increased, receiving in addition the Son of God, that man too might be a partaker of God, so also our way of life is increased in diligence, whence we are commanded not only to abstain from evil deeds but even from such thoughts, and from idle speech, and empty talk, and scurrilous words; and so also the punishment of those who do not believe the Word of God and despise His coming and are turned away backwards is increased, being not merely temporal but made eternal. For to whoever the Lord shall say, 'Depart from me, cursed ones, into everlasting fire,' 3 they shall be damned for ever; and to whomever He shall say, 'Come, blessed ones of my Father, receive the inheritance of the kingdom prepared for you into eternity,' 4 these shall receive the kingdom forever and advance in it.   Saint Ireneaus of Lyons, Against Heresies, Book 4, Ch 28 1 Mt 26.24 2 Mt 10.15 3 Mt 25.41 4 Mt 25.34
