The Bible does not condone it any more. Islam is a younger religion than Christianity. It has not had time to develop and mature.
The Bible actually
never has condoned it. The war against the Canaanite nations had nothing to do with the enforcement of Judaism upon another people. In fact Judaism is a non proselytizing religion. A gentile
can convert to full Judaism if they wish but it is a long process of counseling with rabbi's who actually try to talk you out of converting. This is because Judaism is a very complicated and difficult religion to practice in it's true form. Scads of rules, laws etc. We think of the Ten Commandments when we think of Moses but there are actually 613 commandments in the Mosaic law and the practicing Jew believes they are bound by all of these laws plus all the do's and don'ts of the oral traditions etc.
Again the war against the Canaanite nations was a war of justice. This was for the many murders and child sacrifices the Canaanites were guilty of as a people.
Ge 9:6 Whoso sheddeth man's blood, by man shall his blood be shed: for in the image of God made he man.
This verse states that
by man shall his blood be shed. Not by God. At the end of the Canaanite wars the Israelite armies were to be disbanded, If an aggressor nation were to make war against Israel they were to call up their armies again but these military operations had totally different rules of engagement than the war with the Canaanites had. One of them being,
De 20:10 When thou comest nigh unto a city to fight against it, then proclaim peace unto it.
De 20:11 And it shall be, if it make thee 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 they shall serve thee.
De 20:12 And if it will make no peace with thee, but will make war against thee, then thou shalt besiege it:
Notice that this offer of peace was not nation by nation but settlement by settlement with the nation that Israel was having problems with. No scorched earth policy.
In any of these future wars, The women and children were to be spared.
De 20:14 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 the spoil of thine enemies, which the LORD thy God hath given thee.
De 20:15 Thus shalt thou do unto all the cities which are very far off from thee, which are not of the cities of these nations.
De 20:16 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:
It is the same for Christianity. We were never intended to be an aggressive religion. In fact we never intended to actually be a full-fledged religion. The earliest Christians called our belief "The Way". It was meant to be a way of life rather than a true religion practiced on certain days through ceremony and ritual. As stated it is true that the organized church has spilled it's fair share of innocent blood. But true, real Christianity is actually responsible for much of what is good in the world today. True Christianity started as a seed in a cruel hostile world of empires, wars of conquest slavery etc were all the rule of the land. If you look at the probabilities Christianity should not have survived. For three hundred years Christianity was illegal. It's followers sentenced to death. We had no armies, We did not fight against our persecutors, Instead we prayed for them. We were a pacifist religion. No true organization etc. And yet this belief grew and spread across the Roman empire.
Then came Constantine's vision. We became the accepted religion of the empire and many say that this was the end of the church. But really it was the beginning. Many believe the church became corrupted at this time and we became like the pagans. Maybe if you look at it as the glass is half empty that appears to be true but if you look at it as the glass is half full they also became like us. Basically it is the parable of the wheat and the tares. But in this case it is the wheat that choked out the tares. It is through the efforts of true Christians down through the years that slavery became abolished. Schools, Universities and hospitals were built. Empires were dissolved. War seen as something no longer to be desired. It is no accident that the majority of developed nations with the highest standards of living and education with the most freedoms, rights and privileges happen to be Christian nations.
Even some of the non Christian countries are what they are today because Christians nations banded together and stopped the aggressors that would enslave their populations. Christian nations stopped Japanese aggression in the Pacific. Nazi aggression in Europe. Stopped North Korean aggression in the 50's. Brought about the collapse of Russian communism. The Warsaw pact and the Berlin Wall.
It is Christian nations that bring pressure on oppressive regimes to adhere to human rights and abandon the abuse of their peoples. It is Christian nations that send shiploads of humanitarian aide to to impoverished countries.
It is Christian missionaries in those countries who see to it that the world does not forget these people. Many times at the risk of their own personal safety and well being. So all though yes we have our share of the blame for all that is wrong in the world we also have a greater share of the credit for all that is right in the world also
