It began, as so much these days does, with a group chat. Early this year, around 20 rabbinical and cantorial students started a WhatsApp thread they eventually named "Rad Future Clergy." Among them, they attended rabbinical schools in five different U.S. cities. Several of them first became friends while studying and working in a sixth city, Jerusalem, the capital of the land that both the Torah and Israel's declaration of independence deem the place for "the ingathering of the exiles."
