Chazon Ish said Mizrachi (Modern Orthodox) Jews are ‘-ve’.
The purpose of a Jew is to be completely committed to become a Tzaddik Gammur (a perfect Tzaddik) most of us are Benenim (in between), we aim, though, to completely subdue our evil inclination, and reach the highest level although this may be hard, this must be our aim. The 13 Principles of Faith instruct all Jews to reach this level.
Without commitment to completion, there can be no beginning of a quest (to be a Jew), the philosophy of the Mizrachim where they are satified to be ‘middle of the road’ is wrong.
This can be illustrated the following story.
There was a Aguda Cheder in Isreal that needed to fill its quota to get governmental grants, they had to join with another school (Mizrachi). The Menahalim of the Aguda Cheder asked Chazon Ish’s opinion. The Chazon Ish requested to speak to the Mizrachi administration, if they listened to his request, he would agree to let the schools join. He made a deal with the Mizrachim, that if they would agree to hang pictures of Rabbi Yosef Sonnenlfeld and and the Chofetz Chaim and other Gedolim in the Cheder, he would agree to the joining of the schools. The Mizrachim refused.
Another story once occurred where a Isreal Mizrachi Rabbi came to collect funds for his school, he asked a great Aguda Rabbi to give his Haskamah, the great Rabbi asked, ‘do you want Moshiach to come out of your school’ the Mizrachi Rabbi answered that was a bit of a tall order. The Rabbi replied in that case, I am not giving you the Haskamah, as it says in the Talmud on the verse in Psalm’s and what we say in Shacharis, ‘el tigu b’moshicho’-do not touch my annointed one’s (Moshiach) says the Talmud this refers to Tinokes Shel Beis Rabban (the school Children), if your aim is not to make your Talmidim, Moshiach, then I will not give my Haskamah.
