The answer is: Resurrection

Mark 12:18

The Sadducees were a fascinating group in the Gospels, especially when you consider their beliefs in light of their social and theological context. Chiefly composed of priests and wealthy elites, they exclusively accepted the written Torah—the first five books of the Bible—as their scriptural authority, dismissing the Prophets and Writings, which led to their disbelief in the resurrection of the dead.

Imagine being part of a society deeply divided over key religious leads. The Sadducees had a rather pragmatic approach to life, focusing on the present and scoffing at the idea of an afterlife or any resurrection. This might seem a narrow perspective to many, especially with resurrection later underscored through Jesus’ teachings.

Besides the juicy theological turf battles with the Pharisees, who emphasized oral traditions and a belief in an afterlife, their interactions accent the heart of the divine mystery: the delicate dance between faith, power, and spiritual estate. It is interesting that the word "Sadducee" is sometimes thought to be derived from "Zadok," the name of a high priest in the Old Testament, merging their challenges to ideas about spirituality with ancient traditions.

Their famous run-in with Jesus, when they posed a silly question about marriage in heaven, is a classic example of trying to trap Him in logical puzzles. Yet, Jesus’ acclaim for life beyond earthly existence makes us think about the adventure of faith stretching beyond what we can see. Often, it is our constraints on understanding and belief that form the walls between our experience of the divine. The Sadducees remind us of the importance of having an open heart to new wisdom, particularly concerning eternal truths!
