Objection 1: It would seem that sinners impetrate nothing from God by their prayers. It is written ( Jn. 9:31 ): "We know that God doth not hear sinners"; and this agrees with the saying of Prov. 28:9, "He that turneth away his ears from hearing the law, his prayer shall be an abomination." Now an abominable prayer impetrates nothing from God. Therefore sinners impetrate nothing from God.
Objection 2: Further, the just impetrate from God what they merit, as stated above (A[15], ad 2). But sinners cannot merit anything since they lack grace and charity which is the "power of godliness," according to a gloss on 2 Tim. 3:5, "Having an appearance indeed of godliness, but denying the power thereof." and so their prayer is impious, and yet piety it required in order that prayer may be impetrative, as stated above (A[15], ad 2). Therefore sinners impetrate nothing by their prayers.
Objection 3: Further, Chrysostom [*Hom. xiv in the Opus Imperfectum falsely ascribed to St. John Chrysostom] says: "The Father is unwilling to hear the prayer which the Son has not inspired." Now in the prayer inspired by Christ we say: "Forgive us our trespasses as we forgive them that trespass against us": and sinners do not fulfil this. Therefore either they lie in saying this, and so are unworthy to be heard, or, if they do not say it, they are not heard, because they do not observe the form of prayer instituted by Christ.
On the contrary, Augustine says (Tract. xliv, super Joan.): "If God were not to hear sinners, the publican would have vainly said: Lord, be merciful to me a sinner"; and Chrysostom [*Hom. xviii of the same Opus Imperfectum] says: "Everyone that asketh shall receive, that is to say whether he be righteous or sinful."
I answer that, In the sinner, two things are to be considered: his nature which God loves, and the sin which He hates. Accordingly when a sinner prays for something as sinner, i.e. in accordance with a sinful desire, God hears him not through mercy but sometimes through vengeance when He allows the sinner to fall yet deeper into sin. For "God refuses in mercy what He grants in anger," as Augustine declares (Tract. lxxiii in Joan.). On the other hand God hears the sinner's prayer if it proceed from a good natural desire, not out of justice, because the sinner does not merit to be heard, but out of pure mercy [*Cf. A[15], ad 1], provided however he fulfil the four conditions given above, namely, that he beseech for himself things necessary for salvation, piously and perseveringly.
Reply to Objection 1: As Augustine states (Tract. xliv super Joan.), these words were spoken by the blind man before being anointed, i.e. perfectly enlightened, and consequently lack authority. And yet there is truth in the saying if it refers to a sinner as such, in which sense also the sinner's prayer is said to be an abomination.
Reply to Objection 2: There can be no godliness in the sinner's prayer as though his prayer were quickened by a habit of virtue: and yet his prayer may be godly in so far as he asks for something pertaining to godliness. Even so a man who has not the habit of justice is able to will something just, as stated above (Q[59], A[2]). And though his prayer is not meritorious, it can be impetrative, because merit depends on justice, whereas impetration rests on grace.
Reply to Objection 3: As stated above (A[7], ad 1) the Lord's Prayer is pronounced in the common person of the whole Church: and so if anyone say the Lord's Prayer while unwilling to forgive his neighbor's trespasses, he lies not, although his words do not apply to him personally: for they are true as referred to the person of the Church, from which he is excluded by merit, and consequently he is deprived of the fruit of his prayer. Sometimes, however, a sinner is prepared to forgive those who have trespassed against him, wherefore his prayers are heard, according to Ecclus. 28:2, "Forgive thy neighbor if he hath hurt thee, and then shall thy sins be forgiven to thee when thou prayest."
Whether the parts of prayer are fittingly described as supplications, prayers, intercessions, and thanksgivings?
Objection 1: It would seem that the parts of prayer are unfittingly described as supplications, prayers, intercessions, and thanksgivings. Supplication would seem to be a kind of adjuration. Yet, according to Origen (Super Matth. Tract. xxxv), "a man who wishes to live according to the gospel need not adjure another, for if it be unlawful to swear, it is also unlawful to adjure." Therefore supplication is unfittingly reckoned a part of prayer.
Objection 2: Further, according to Damascene (De Fide Orth. iii, 24), "to pray is to ask becoming things of God." Therefore it is unfitting to distinguish "prayers" from "intercessions."
Objection 3: Further, thanksgivings regard the past, while the others regard the future. But the past precedes the future. Therefore thanksgivings are unfittingly placed after the others.
On the contrary, suffices the authority of the Apostle ( 1 Tim. 2:1 ).
I answer that, Three conditions are requisite for prayer. First, that the person who prays should approach God Whom he prays: this is signified in the word "prayer," because prayer is "the raising up of one's mind to God." The second is that there should be a petition, and this is signified in the word "intercession." In this case sometimes one asks for something definite, and then some say it is "intercession" properly so called, or we may ask for some thing indefinitely, for instance to be helped by God, or we may simply indicate a fact, as in Jn. 11:3, "Behold, he whom Thou lovest is sick," and then they call it "insinuation." The third condition is the reason for impetrating what we ask for: and this either on the part of God, or on the part of the person who asks. The reason of impetration on the part of God is His sanctity, on account of which we ask to be heard, according to Dan. 9:17 , 18 "For Thy own sake, incline, O God, Thy ear"; and to this pertains "supplication" [obsecratio] which means a pleading through sacred things, as when we say, "Through Thy nativity, deliver us, O Lord." The reason for impetration on the part of the person who asks is "thanksgiving"; since "through giving thanks for benefits received we merit to receive yet greater benefits," as we say in the collect [*Ember Friday in September and Postcommunion of the common of a Confessor Bishop]. Hence a gloss on 1 Tim. 2:1 says that "in the Mass, the consecration is preceded by supplication," in which certain sacred things are called to mind; that "prayers are in the consecration itself," in which especially the mind should be raised up to God; and that "intercessions are in the petitions that follow, and thanksgivings at the end."
We may notice these four things in several of the Church's collects. Thus in the collect of Trinity Sunday the words, "Almighty eternal God" belong to the offering up of prayer to God; the words, "Who hast given to Thy servants," etc. belong to thanksgiving; the words, "grant, we beseech Thee," belong to intercession; and the words at the end, "Through Our Lord," etc. belong to supplication.
In the "Conferences of the Fathers" (ix, cap. 11, seqq.) we read: "Supplication is bewailing one's sins; prayer is vowing something to God; intercession is praying for others; thanksgiving is offered by the mind to God in ineffable ecstasy." The first explanation, however, is the better.
Reply to Objection 1: "Supplication" is an adjuration not for the purpose of compelling, for this is forbidden, but in order to implore mercy.
Reply to Objection 2: "Prayer" in the general sense includes all the things mentioned here; but when distinguished from the others it denotes properly the ascent to God.
Reply to Objection 3: Among things that are diverse the past precedes the future; but the one and same thing is future before it is past. Hence thanksgiving for other benefits precedes intercession: but one and the same benefit is first sought, and finally, when it has been received, we give thanks for it. Intercession is preceded by prayer whereby we approach Him of Whom we ask: and prayer is preceded by supplication, whereby through the consideration of God's goodness we dare approach Him.
