Wars of Extermination.
And when thou comest nigh unto a city to fight against it, and it shall be, if it make the answer of peace, and open unto thee, then it shall be, that all the people that is found therein shall be tributaries unto thee and shall serve thee. And if it will make no peace with thee, but will make war against thee (that is, by defending their wives and children) then thou shalt besiege it.
And when the Lord God hath delivered it into thine hands, thou shalt smite every male thereof with the edge of the sword; but the women and the little ones, and the cattle, and all that is in the city, even all the spoil thereof, shalt thou take unto thyself, and thou shalt eat of the spoil of thine enemies, which the Lord thy God hath given thee. Thus shalt thou do unto all the cities which are very far off from thee, which are not of the cities of these nations. But of the cities of these people, which the Lord thy God doth give thee for an inheritance, thou shalt save alive nothing that breatheth. ([Deut. 20 : 10–17].)
So Joshua smote all the country of the hills, and of the south, and of the vale, and of the springs and all their kings; he left none remaining, but utterly destroyed all that breathed as the Lord God of Israel had commanded. ([Joshua 10 : 40].)
Thus saith the Lord of hosts, I remember that which Amelek did to Israel (some three hundred years previous), how he laid wait for him in the way when he came up from Egypt. Now go and smite Amelek, and utterly destroy all that they have and spare them not, but slay both man and woman, infant and suckling, ox and sheep, camel and ass. ([1 Sam. 15 : 2, 3].)
Now, therefore, kill every male among the little ones, and kill every woman that hath known man by lying with him.
But all the women children that have not known a man by lying with him, keep alive for yourselves. ([Numbers 31 : 17, 18].)
To believe these bloody massacres to have been done by the express command of the supreme ruler of the universe, made man brutal and despotic. And it is for this very reason that we have had so many wars among Christian nations. The Old Testament is a record of cruelty and blood; and if we fall back in time on this side of the cross of Christ, we shall find the same spirit, and the same bloody deeds perpetrated upon all those who were not numbered as the peculiar people of God. Constantine established Christianity in the Roman empire by the sword; and his holy successors have maintained it by the same power ever since.
Polygamy.
Although Christians now condemn polygamy, they uphold a Bible that not only approves it, but also shows distinctly that God instituted it.
