In this episode, I discuss three genres of halakhic writing: codes, commentaries ("nosei Kelim"), and responsa (teshuvot). Each genre has specific objectives and goals. After a discussion of commentaries, I begin the discussion of codes vs. responsa by looking at the rulings of Rav Melamed and Rav Asher Weiss on a particular issue, one that is the subject of much controversy. Through this we start to get a glimpse of why Rav Melamed has begun to face opposition.
