(b) Tradition and the Historical Development in Doctrine and Practice — The doctrine of Scripture about the illicitness of divorce is fully confirmed by the constant tradition of the Church. The testimonies of the Fathers and the councils leave us no room for doubt. In numerous places they lay down the teaching that not even in the case of adultery can the marriage bond be dissolved or the innocent party proceed to a new marriage. They insist rather that the innocent party must remain unmarried after the dismissal of the guilty one, and can only enter upon new marriage in case death intervenes.
We read in Hermas (about the year 150), “Pastor”, mand. IV, I, 6: "Let him put her (the adulterous wife) away and let the husband abide alone; but if after putting away his wife he shall marry another, he likewise committeth adultery (ed. Funk, 1901). The expression in verse 8, “For the sake of her repentance, therefore, the husband ought not to marry”, does not weaken the absolute command, but it gives the supposed reason of this great command. St. Justine Martyr (d. 176) says (Apolog., I, xv, P.G., VI, 349), plainly and without exception: “He that marrieth her that has been put away by another man committeth adultery.” In like manner Athenagoras (about 177) in his Plea for the Christians 33: “For whosoever shall put away his wife and shall marry another, committed adultery”; Tertullian (d. 247), “De monogamiâ”, c, ix (P.L., II, 991): “They enter into adulterous unions even when they do not put away their wives, we are not allowed to even marry although we put our wives away”; Clement of Alexandria (d. 217) (Stromata II.23) mentions the ordinance of Holy Scripture in the following words; “You shall not put away your wife except for fornication, and [Holy Scripture] considers as adultery a remarriage while the other of the separated persons survives.” Similar expressions are found in the course of the following centuries both in the Latin and in the Greek Fathers, e.g. St. Basil of Cæsarea, “Epist. can.”, ii, “Ad Amphilochium”, can. xlviii (P.G., XXXII, 732); St. John Chrysostom, “De libello repud.” (P.G., LI, 218); Theodoretus, on I Cor., vii, 39, 40 (P.G., LXXXII, 275); St. Ambrose, “in Luc.”, VIII, v, 18 sqq. (P.L., XV, 1855); St. Jerome, Epist. lx (ad Amand.), n. 3 (P.L., XXII, 562); St. Augustine, “De adulterinis conjugiis”, II, iv (P.L., XL, 473), etc., etc. The occurrences of passages in some Fathers, even among those just quoted, which treat the husband more mildly in case of adultery, or seem to allow him a new marriage after the infidelity of his spouse, does not prove that these expressions are to be understood of the permissibility of a new marriage, but of the lesser canonical penance and of exemption from punishment by civil law. Or if they refer to a command on the part of the Church, the new marriage is supposed to take place after the death of the wife who was dismissed. This permission was mentioned, not without reason, as a concession for the innocent party, because at some periods the Church’s laws in regard to the guilty party forbade forever any further marriage (cf. can. vii of the Council of Compiègne, 757). It is well known that the civil law, even of the Christian emperors, permitted in several cases a new marriage after the separation of the wife. Hence, without contradicting himself, St. Basil could say of the husband, “He is not condemned”, and “He is considered excusable” (ep. clxxxviii, can. ix, and Ep. cxcix, can. xxi, in P.G., XXXII, 678, 721), because he is speaking distinctly of the milder treatment of the husband than of the wife with regard to the canonical penance imposed for adultery. St. Epiphanius, who is especially reproached with teaching that the husband who had put away his wife because of adultery or another crime was allowed by Divine law to marry another (Hæres, lix, 4, in P.G., XLI, 1024), is speaking in reality of a second marriage after the death of the divorced wife, and whilst he declares in general that such a second marriage is allowed, but is less honourable, still he makes the exception in regard to this last part in favour of one who had long been separate from his first wife. The other Fathers of the following centuries, in whose works ambiguous or obscure expressions may be found, are to be explained in like manner.
