3. No devotions might be made within two years before the jubilee, nor redemptions within the year following it. If a son redeemed his father's land, he was to restore it to him in the jubilee (Erakin, 7:3).
4. A man might devote some of his flock, herd, and heathen slaves, but not all these (Erakin 8:4).
5. Devotions by priests were not redeemable, but were transferred to other priests (Erakin, 8:6).
6. A man who vowed not to sleep on a bed, might sleep on a skin if he pleased (Otho, Lex. Rabb. p. 673).
7. The sums of money arising from votive consecrations were divided into two parts, sacred (1) to the altar; (2) to the repairs of the Temple (Reland, Ant. 10:4).
It seems that the practice of shaving the head at the expiration of a votive period was not limited to the Nazarite vow (Act_18:18; Act_21:24).
II. Christian Vows. The practice of vows, though evidently not forbidden, as the above case of Paul (Act_18:18) serves to show, does not seem to have been at all common in the apostolical Church. With the civil establishment under Constantine, however, and especially under the growing influence of monasticism, it early gained extensive and powerful prevalence. Bingham cites the ecclesiastical instances and regulations chiefly affecting church property and religious orders (Christ. Aniq. bk. 16: 150, 7:§ 9), but they apply mostly to medieval times.
“There is some difference of opinion respecting the origin and extent of monastic vows. Some authors affirm that they were made legally binding and indissoluble as early as the Council of Chalcedon; but the more general opinion is that, though considered obligatory in foroa conscientice, according to their nature, no civil disability or irreversible obligation was incurred by them till the time of Boniface VIII, late in the 13th century. The three solemn vows, as they are termed, of the monastic orders are poverty, chastity, and obedience, to which others are occasionally annexed by certain religious orders. For example, the fourth vow of the Jesuits places every member at the absolute disposal of the Roman pontiff, to be employed by him in whatever service may be thought most to the advantage of the Holy See. The earliest lawful age for embracing the monastic profession has varied at different periods and in different countries; it was fixed by the Council of Trent at sixteen years, before which period no religious vow is of any legal validity. Within the first five years the vow may be protested against on the ground of want of consent, insufficient age, or irregularity of novitiate; but after the expiration of that period it is held to be indissoluble. Certain extraordinary vows for instance, that of pilgrimage to Rome — can only be dispensed with by the pope; others may be relaxed by the intervention of the ordinary of the diocese.” SEE MONASTICISM.
In the Church of Rome the subject of vows assumes extraordinary proportions. “The objects of these engagements among Catholics are very various; but they are drawn, for the most part, from what are called the evangelical ‘counsels,' in contradistinction to ‘precepts' or ‘commands' — the most ordinary subject of vows being the so-called ‘evangelical' virtues of poverty, chastity, and obedience. Pilgrimages, however, acts of abstinence, or other self-mortifications, whether of the body or of the will, special prayers or religious exercises, are frequently made the object of vows; and there is another large class of more material objects, as the building of churches, monasteries, hospitals, and other works of public interest or utility, to which mediaeval Europe was indebted for many of its most magnificent memorials of piety and of art. Vows, in the Roman Church law, are either ‘simple' or ‘solemn.' The principal difference between them consists in the legal effects of the ‘solemn' vow, which, where the subject of such vow is chastity, renders not merely unlawful, but null and void, a marriage subsequently contracted. A ‘simple' vow of chastity makes it unlawful to marry, but, except in the Jesuit Society, does not invalidate a marriage, if subsequently contracted. Catholics acknowledge in the Church a power of dispensing in vows; but this is held to be rather declaratory than remissory, and it is not acknowledged in the case of vows which involve any right of a third party. Bishops are held to possess the power of dispensing in simple vows generally; but the power of dispensing in solemn vows and in. certain simple vows as, for example, that of absolute and perpetual chastity, and of the greater pilgrimages is reserved to the pope. The practical operation of the canon law regarding vows has evidently been much modified, even in Catholic countries, since the French Revolution, and the subsequent political changes; but this must be understood to regard chiefly their external aid purely juridical effects. So far as concerns their spiritual obligation, the modern Roman theology recognizes little, if any, change.” See Wetter und. Velte, Kircleni-Lex. s.v.
