The first of these, that is to say, the Judging whether it be a sinne or not, belongs to the Interpreter of the Law, that is, the Soveraign Judge; the second, namely Remission, or retention of the sinne, to the Pastor, and it is that concerning which the power of binding and loosing is conversant. And that this was the true meaning of our Saviour Christ in the institution of the same power, is apparent in the 18 of Mat. vers. 15, 16, 17, 18. thus, He there speaking to his Disciples, sayes, If thy Brother sinne against thee, goe, and tell him his fault betweene thee and him alone, (where we must observe by the way, that if thy Brother sinne against thee, is the same with, if he doe thee injury; and therefore Christ spake of those matters which belonged to the civill Tribunall) he addes, if he heare thee not (that is to say, if he deny that he hath done it, or if having confest the fact, he denies it to be unjustly done) take with thee yet one or two, and if he refuse to heare them, tell it the Church. But why to the Church, except that she might judge whether it were a sinne or not? But if he refuses to hear the Church, that is, if he doe not submit to the Churches sentence, but shall maintain that to be no sin, which She Judges to be a sinne, that is to say, if he repent not (for certain it is that no man repents himselfe of that action which She conceives not to be a sinne) he saith not, Tell it to the Apostles, that we might know that the definitive sentence in the question, whether it were a sin or not, was not left unto them, but to the Church; but let him be unto thee (sayes he) as an Heathen, or Publican, that is, as one out of the Church, as one that is not baptized, that is to say, as one whose sinnes are retained. For all Christians were baptized into remission of sinnes. But because it might have been demanded who it was that had so great a power, as that of withholding the benefit of Baptisme from the impenitent, Christ shewes that the same Persons to whom he had given authority to baptize the penitent into the remission of sinns, and to make them of heathen men, Christians, had also authority to retain their sins who by the Church should be adjudged to be impenitent, and to make them of Christian men Heathens; and therefore presently subjoynes, Verily I say unto you, Whose soever sinnes yee shall binde upon Earth, they shall bee bound also in Heaven, and whose soever sins yee shall loose upon Earth, they shall be loosed also in Heaven.
Whence we may understand, that the power of binding, and loosing, or of remitting, and retaining of sinnes, which is called in another place, the power of the keyes, is not different from the power given in another place in these words, Goe, and teach all Nations, Baptizing them in the Name of the Father, and of the Sonne, and of the Holy Ghost, Mat. 28. ver. 19. And even as the Pastours cannot refuse to Baptize him whom the Church judges worthy, so neither can they retaine his sinnes whom the Church holds fitting to be absolv'd, nor yet remit his sinnes whom the Church pronounceth disobedient. And it is the Churches part to judge of the sinne, the Pastours, to cast out, or to receive into the Church those that are judg'd. Thus Saint Paul to the Church of Corinth, Do not ye judge, saith he, of those that are within?
Yet he himself pronounc't the sentence of Excommunication against the incestuous Person, I indeed (saith he) as absent in body, but present in Spirit, &c.
XXVI. The act of retaining sinnes is that which is called by the Church Excommunication, and by Saint Paul, delivering over to Satan. The word Excommunication, sounding the same with aposunagogon poiein, casting out of the Synagogue, seems to be borrowed from the Mosaicall Law, wherein they who were by the Priest adjudged leprous, were commanded to be kept apart out of the Camp, untill by the judgement of the Priest they were againe pronounc't cleane, and by certaine rights (among which the washing of the body was one) were purified, Levit. 13. ver. 46.
From hence in processe of time it became a custome of the Jewes, not to receive those who passed from Gentilisme to Judaisme, (supposing them to be uncleane) unlesse they were first washed; and those who dissented from the Doctrine of the Synagogue, they cast out of the Synagogue. By resemblance of this custome, those that came to Christianity, (whether they were Jewes, or Gentiles) were not receiv'd into the Church without Baptisme; and those that dissented from the Church were depriv'd of the Churches Communion. Now, they were therefore said to be deliver'd over to Satan, because all that was out of the Church, was comprehended within his Kingdome. The end of this kind of Discipline was, that being destitute for a time of the grace and spirituall priviledges of the Church, they might be humbled to salvation.
