But the deeper reason the colonists had for excluding slaves from baptism, and hence citizenship, was twofold; viz., to keep in harmony with the Mosaic code in reference to "strangers" and "Gentiles," and to keep the door of the Church shut in the face of the slave; because to open it to him was to emancipate him in course of time. Religious and secular knowledge were not favorable to slavery. The colonists turned to the narrow, national spirit of the Old Testament, rather than to the broad and catholic spirit of the New Testament, for authority to withhold the mercies of the Christian religion from the Negro slaves in their midst. The rigorous system of domestic slavery established in the colony of Massachusetts bore its bitter fruit in due season. It was impossible to exclude the slaves from the privileges of the Church and State without inflicting a moral injury upon the holy marriage relation. In the contemplation of the law the slave was a chattel, an article of merchandise. The custom of separating parent and child, husband and wife, was very clear proof that the marriage relation was either positively ignored by the institution of slavery, or grossly violated under the slightest pretext. All well-organized society or government rests upon this sacred relation. But slavery, with lecherous grasp and avaricious greed, trailed the immaculate robes of marriage in the moral filth of the traffic in human beings. True, there never was any prohibition against the marriage of one slave to another slave,--for they _tried_ to breed slaves in Massachusetts!--but there never was any law encouraging the lawful union of slaves until after the Revolutionary War, in 1786. We rather infer from the following in the Act of October, 1705, that the marriage relation among slaves had been left entirely to the caprices of the master. "And no master shall unreasonably deny marriage to his Negro with one of the same nation; any law, usage or custom to the contrary notwithstanding."[330] We have not been able to discover "any law" positively prohibiting marriage among slaves; but there was a custom denying marriage to the Negro, that at length received the weight of positive law. Mr. Palfrey says,-- "From the reverence entertained by the fathers of New England for the nuptial tie, it is safe to infer that slave husbands and wives were never separated."[331]
