An Ancient List of Christian Festivals in Toledot Yeshu: Polemics as Indication for Interaction

Abstract

Calendars, liturgy, and especially festivals offer a convenient vantage point from which to analyze collective identities. They can provide access to group mentalities rather than to the ideas of individual intellectuals, which are often more or less confined to ivory towers.1 Ritual addresses the whole human being—the intellect, emotions, and body—and it does so by establishing and defining relations between the individual, his or her in-group, and the out-group.2 Every collective identity is formed and reformed in a continuous process encompassing exchange with, as well as distinction from, other possible collective identities.3 Sometimes, this construction of a “we” in distinction from “them” is explicit, while at other times it takes place in a more clandestine and encrypted fashion.
