[T]he beit din must not allow rabbis of ordinary stature to rule on matters of great complexity or import (see Teshuvot Meishiv Davar 4:50). For example, the Noda Biy'hudah (vol. 2, Y.D. 88) criticizes an ordinary rabbi for ruling on a case of ro'eh machmat tashmish, a complex area of the laws of family purity that can potentially result in forcing a couple to divorce (see Shulchan Aruch, Yoreh Deah 187). Rav Moshe Feinstein (Teshuvot Igrot Moshe, Even Ha'ezer 1:64) similarly writes that ordinary rabbis should not rule on matters of contraception.[13]

[13] Regarding the pervasiveness of this problem in our generation, see Nishmat Avraham (4:13-16) and Rav Tzvi Gartner's essay in Tradition (32:3:94-95). See also Pitchei Teshuvah (Y.D. 99:6).

I also received support regarding my decision to attend YC from an unexpected source. My mother was a first cousin of R. Avraham Karelitz — the Hazon Ish — the Talmudic luminary of the first half of the twentieth century and my parents’ shadkhan. During the last fifteen years of his life, the Hazon Ish lived in the modest home of my uncle, R. Gershon Schreibman, who would come each summer to the United States “tzu kempfen par shabbos” — to do battle for Sabbath observance. When I completed my sophomore year in high school, my uncle suggested that it would be a good idea to seek guidance from the Hazon Ish regarding the choice of a yeshiva in New York to attend after the completion of high school. My father, known as the Brezer Illui in Lithuania, skeptically agreed. There were four possibilities for me: Mesivta Torah Vodaath, Yeshivat Chaim Berlin, Mesivta Tifereth Jerusalem, where R. Shmuel Greineman, cousin of both the Hazon Ish and my mother, was the menahel, and RIETS.

The following summer, my uncle returned with a Yiddish note penned on a brown paper bag. Translated, the message said: “Avremeleh [my Yiddish name], I think that it is a good idea for you to study in Revel’s yeshiva. There you can excel in learning if you so desire. Moreover, you could study for a trade or profession in the secular department. But, remember, in the cold weather you should wear a warm coat.” This latter reference refers to the environment in which I would be exposed to secular studies. In order not to be unduly influenced, I would need Judaic reinforcement.
