A man once asked the Chofetz Chaim, “Why are there so many different groups of Jews? There are Chasidim and Misnagdim. And even among the Chasidim, there are so many factions. Some emphasize learning over Davening, while others Daven at length but learn only a little. Some focus on music and songs, and others prefer dancing. Why can’t we have just one group of Jews that all Davened the same way and had the same customs?”
The Chofetz Chaim responded, “Before you ask me about the different groups within our nation, go and ask the Czar of Russia why he has so many different types of soldiers and fighters. He has soldiers that fight on the ground, and those that go by horse. He has some that go by air, and others that are navy sailors.
Ask him, ‘What would be so bad if you had only one type of soldier to fight for you? It’s all under one commander that would lead them anyway.’ He would answer that since he has to go out to war and defeat the enemy, he must use a mixture of strategy to do this. Some soldiers use swords to fight, but others cannot. Those on a horse fight differently than those who go by air or sea.
“It is the same thing when it comes to the war against the Yetzer Hara. All of the different groups in Judaism are soldiers fighting for the same cause of Hashem. They each have their own way of contributing to help defeat the enemy. One’s strength is in learning Torah, another’s is in Davening, and yet another’s is with song. All that is important is that their hearts are loyal to their Father, Hashem, in Shamayim!”
