Christians are not called the children of Abraham because they imitate his example in war, but because they exercise like precious faith with him. If Christians are warranted to imitate the example of Abraham in all things which were tolerated by God, then they may sacrifice cattle, practice polygamy, and buy and hold slaves. But if they object to his example as a rule of duty in these instances, why not object to his example as a rule of duty in the case of war? But to say that he acted from some universal law still in force is taking for granted the question in dispute, and cannot be admitted without evidence. The war waged by Abraham against the kings was, I apprehend, offensive rather than defensive; for Lot, his brother's son, whom he rescued, did not then belong to his family or kingdom, but was separated from him and was also a patriarch, a father of nations, and a prince or head over his own house or kingdom. It appears very evident that offensive as well as defensive war was tolerated under the patriarchal economy, as may be seen from the words of the inspired Jacob when blessing his sons (Gen. xlviii. 22). That, as well as the Mosaic dispensation, was typical, and doubtless war was allowed under both for the same reasons. But there can be no doubt that whoever attempts to justify war by the example of Abraham may equally justify the slavery of our fellow-men; and whoever depends on his example for authority for engaging in war, to be consistent, must advocate and defend the doctrine of slavery. _Objection sixth._ It appears to be a universal law of God that "whoso sheddeth man's blood, by man shall his blood be shed." If one man, or one nation, attacks another and sheds his blood, his own must be shed in return. Hence this precept not only authorizes taking away the life of a murderer, but authorizes nations to repel by war nations that wage war against them. _Answer._ Whether this was a precept given to man as a rule of duty or not is very questionable, though it has generally been so construed, at least since the dark ages of the church; and it is still more questionable whether it is a universal and perpetual law.
