Following the Russian Revolution, he was at the forefront of opposition to the Communist government's attempts to repress the Jewish religion and culture. During this time he would serve as both the Rabbi of Slutsk and Smolensk. As a result, the Soviet government refused Abramsky permission to leave and take up the rabbinate of Petah Tikva in Palestine in both 1926 and 1928. In 1926, while serving as the rabbi of Slutsk, he joined (together with Rabbi Shlomo Yosef Zevin) the "Vaad Harabbonim of the U.S.S.R".
