As it is natural to expect, that whatever exhibition of privileges the parents enjoyed should be extended to their children, in common with themselves; so we find that in fact they are expressly included in this dispensation as well as the preceding. The covenant is established between God and Abraham’s seed, in the very same sense as with Abraham himself; the essence of which is—to be a God to him and his seed. And lest it should be objected that the term seed refers to his adult posterity who should tread in his steps, to the exclusion of infants, all doubt is dissipated by the appointment of applying the seal of the covenant in early infancy.

Sacrifices continuing in full force to seal the covenant, till the divine oblation should be made; and the bow of the covenant continuing as a token and seal of it, until the Messiah’s second coming; at the commencement of this period is given an additional seal—circumcision. The very nature of the rite shews that all females are excluded from being the subjects of it; as well as the discriminating specification—every man-child. Here observe in general, that children, in this rite, have the same privileges as their parents. The males are treated as Abraham, and the females as Sarah: These therefore, had the covenant sealed in the same manner as their honoured mother. Again: though Sarah and her sex were not the subjects of this rite, they were constant witnesses to the institution; and therefore there was an important sense in which circumcision was a seal to Sarah and her daughters; a sense analagous to that in which sacrifices were.

Every domestic head being, in truth, a prophet, priest, and king, in his own family; a question must arise, Whether the covenant and its seals are restricted to the parent head of the family, and his children, or else extended to the other domestics? Nor would the question be unimportant; for his instructions, his prayers, and commands, answerable to his three-fold office, must be directed accordingly. To this question right reason replies: If the covenant and its seals are beneficial to all capable subjects, benevolence requires that they should be extended to the other non-dissenting members—except forbidden by indisputable authority. This is the voice of reason; and we find that this is the voice of God. The privilege is common to the seed, and to him that is born in the house, or bought with money of any stranger, which is not of the seed, Gen. xvii. 12.

It has been objected, “that the covenant with Abraham was a covenant of peculiarity only, and that circumcision was no more than a token of that covenant;” but if so, as Mr. Henry observes, “how came it that all proselytes, of what nation soever, even the strangers, were to be circumcised; though not being of any of the tribes, they had no part or lot in the land of Canaan? The extending the seal of circumcision to proselyted strangers, and to their seed, was a plain indication, that the New Testament administration of the covenant of grace would reach, not to the covenanters only, but their seed.” But it has been proved that circumcision sealed to Abraham and his seed the righteousness of faith; and therefore it does not affect the point in debate to contend that temporal promises were sealed also.

We next appeal to the long and interesting period from Moses to Christ, On which let the following observations be considered.

Whatever appertained to the Abrahamic covenant was not disannulled by the Mosaic dispensation. This St. Paul asserts in plain terms, Gal. iii. 17.

It may not be amiss to take notice, before we proceed, of Job’s family; who, being as is generally supposed, cotemporary with Moses, and unconnected with his history, deserves a previous regard. Of him it is said, that “he sanctified his children, and rose up early in the morning, and offered burnt-offerings, according to the number of them all—Thus did Job continually,” or, all the days. (Job i. 5.) On this I would only observe, let the sanctifying be what it may, the sacrifices must have been of divine institution; and used by Job, being an eminently righteous man, as the seals of the covenant of grace; with respect to his children separately.

Superadded to the foregoing seals of the covenant, is the passover; a divine rite of the nature of a sacrifice, instituted in memory of Israel’s deliverance out of Egypt, representing and sealing spiritual blessings. “As to the guests, says Witsius, they were, first, all native Israelites, who were not excluded by legal uncleanness. For all the congregation of Israel is commanded to solemnize the passover. And, next, the Proselytes circumcised and become Jews; whether bondmen born in the house or bought with money, &c. Exod. xii. 48. When a stranger will sojourn with thee, and keep the passover to the Lord, let all his males be circumcised, and then let him come near and keep it, and he shall be as one that is born in the land.” On this passage in Exodus, Dr. Jennings observes these two things; “First, That when a man thus became a Proselyte, all his males were to be circumcised as well as himself, whereby his children were admitted into the visible church of God, in his right, as their father. Secondly, That upon this, he should be entitled to all the privileges and immunities of the Jewish church and nation as well as be subject to the whole law: He should be as one born in the land.” In short; not only men and women, but also young children partook of this ordinance, as soon as they were capable of answering the revealed design of it, for—no positive rule was given them on this head, like that of circumcision. It is manifest that since the injunction respected not only individuals of such a description, but also families as such, every member without exception had a legal right to the ordinance; and nothing prevented infants from a participation, but what lay in the natural incapacity to answer the design of it.

“Besides the ordinary and universal sacraments of circumcision and the passover, some extraordinary symbols of divine grace were granted to the Israelites in the wilderness, which in the New Testament are applied to Christ and his benefits, and said to have the same signification with our sacraments. And they are in order these—The passage in the cloud through the Red Sea—the manna which was rained from heaven—The water issuing out of the rock—and the brazen serpent erected by Moses for the cure of the Israelites.” To this we may add, among other things, with the author now referred to—the clear and familiar display of the divine majesty—and the adumbration of divine mysteries daily sealed by religious ceremonies. Our subject does not call for an investigation of these particulars, but I would remark in general, that the principle for which we contend, is so far from being weakened, that it is abundantly corroborated by the inspired testimony of every dispensation, and the Mosaic in particular—That it is a common dictate of right reason, children should from their earliest infancy share in their parents’ privileges, as far as they are capable, when no positive authority contravenes it.

From the preceding induction of sacred evidence in favour of children being sharers of the seals of grace in common with their parents, we conclude, that for the space of four thousand years, that is to say, from the creation to Christ, it was a rule universally incumbent on parents to treat their children as entitled to religious privileges equally with themselves, according to their capacity.—And as a counterpart of what was observed of privileges, we may remark that, in virtue of the same uniform principle, often when the parents were punished with excommunication or death, their infant children were included with them. As might be instanced in—the deluge—the destruction of Sodom and Gomorrah—the case of Achan the Son of Zerah (Josh. vii. 24.)—the matter of Korah, Dathan, and Abiram—the case of the conquered nations (Deut. xx. 16, 17.)—and many more instances, down to the destruction of Jerusalem. Far be it from us to suppose, that the parents’ crimes and impenitence made their suffering children incapable of mercy—that mercy which proceeds on an invisible plan, and belongs to a purely spiritual dispensation. Yet, that children, during their dependence on their parents, should share equally with them in judgment and mercies externally, is the effect of an all-wise constitution coeval with mankind.
