R. Grodzinski was a vehement opponent of Zionism and of secular education for Jews, his aim being to preserve the Torah milieu of the Lithuanian yeshivot and townlets intact. In 1934 he prevented the transfer of the Hildesheimer rabbinical seminary from Berlin to Tel Aviv. Asked by an Agudat Israel kibbutz whether it was permitted to settle on Jewish National Fund land, he advised its members "Let him who is firm in spirit stay steadfast in his place and not hurry to join the swelling stream... until G-d has mercy on His people and hastens his redemption." In 1929, when R. Isaac Rubinstein was chosen as chief rabbi of Vilna, R. Grodzinski's supporters sparked a violent controversy in the community. R. Grodzinski's responsa were published in three volumes under the title of Ahi'ezer (1922, 1925, 1939). In the introduction to the last volume, written on the eve of the Holocaust, he spoke of the fear and dismay that was rapidly descending upon the entire Jewish people, both in the Diaspora and (in a reference to the 1936–39 riots) in Erez Israel. He wrote about the spiritual disintegration of the Jewish community, and its laxity in the observance of the Sabbath, kashrut, and the laws of marital purity. All this he blamed on the Reform movement in the West and on secular education in the East. His sole consolation was in "the important work of preserving and strengthening Torah education" and in the fact that "the large and small yeshivot were the strongholds of Judaism... in Poland and Lithuania."
