As to this question, it cannot be doubted that the Fathers considered penance as not a mere expression of contrition, but as an act done directly towards God and a means of averting His anger. "If the sinner spare not himself, he will be spared by God," says the writer who goes under the name of St. Ambrose. "Let him lie in sackcloth, and by the austerity of his life make amends for the offence of his past pleasures," says St. Jerome. "As we have sinned greatly," says St. Cyprian, "let us weep greatly; for a deep wound diligent and long tending must not be wanting, the repentance must not fall short of the offence." "Take heed to thyself," says St. Basil, "that, in proportion to the fault, thou admit also the restoration from the remedy."[387:2] If so, the question follows which was above contemplated,--if in consequence of death, or in the exercise of the Church's discretion, the "_plena pœnitentia_" is not accomplished in its ecclesiastical shape, how and when will the residue be exacted? § 4. _Purgatory._ Clement of Alexandria answers this particular question very distinctly, according to Bishop Kaye, though not in some other points expressing himself conformably to the doctrine afterwards received. "Clement," says that author, "distinguishes between sins committed before and after baptism: the former are remitted at baptism; the latter are purged by discipline. . . . The necessity of this purifying discipline is such, that if it does not take place in this life, it must after death, and is then to be effected by fire, not by a destructive, but a discriminating fire, pervading the soul which passes through it."[388:1] There is a celebrated passage in St. Cyprian, on the subject of the punishment of lapsed Christians, which certainly seems to express the same doctrine. "St. Cyprian is arguing in favour of readmitting the lapsed, when penitent; and his argument seems to be that it does not follow that we absolve them simply because we simply restore them to the Church. He writes thus to Antonian: 'It is one thing to stand for pardon, another to arrive at glory; one to be sent to prison (_missum in carcerem_) and not to go out till the last farthing be paid, another to receive at once the reward of faith and virtue; one thing to be tormented for sin in long pain, and so to be cleansed and purged a long while by fire (_purgari diu igne_), another to be washed from all sin in martyrdom; one thing, in short, to wait for the Lord's sentence in the Day of Judgment, another at once to be crowned by Him.' Some understand this passage to refer to the penitential discipline of the Church which was imposed on the penitent; and, as far as the context goes, certainly no sense could be more apposite. Yet . . . the words in themselves seem to go beyond any mere ecclesiastical, though virtually divine censure; especially '_missum in carcerem_' and '_purgari diu igne_.'"[389:1] 2.
