In this installment we consider the (in)famous decision of Rabbi Moshe Feinstein, the preeminent 20th-century Orthodox posek in North America, concerning Reform Jewish weddings. Spoiler alert #1: he thinks that they do not produce valid Jewish marriages according to halakhah. Spoiler alert #2: his ruling served a purpose that all of us progressive types can support, even if what he says about us is vituperative and insulting. As we like to say in the halakhah business: it's complicated. Which is why it's so interesting.
