Among the Jewish people, it was widely believed that in addition to the written Law, God had imparted an unwritten law to Moses that was handed down orally—first to Joshua, then to the judges and prophets. This oral tradition, distinct from the written Law, consisted of the teachings and interpretations provided by rabbis across generations. Regrettably, these man-made traditions gained the unshakeable respect of the populace, who, led by the scribes and Pharisees, prioritized the letter of the law over its true intent, often neglecting the divine truths encapsulated in the Torah of Moses. The intricate and at times trivial stipulations of this oral law became known as the “traditions of the elders,” which were meticulously followed, often with greater devotion than the moral imperatives of God’s Law as outlined in the Pentateuch.
The societal life of Judea became ensnared in the traditions of these misguided interpreters of Divine revelation, who imposed burdensome regulations on the people (Matt. 23:4). On this occasion, the Pharisees and scribes reprimanded the disciples of Jesus for failing to observe the ceremonial washings required by the Law of Moses (Lev., ch. 11), which detailed the division of clean and unclean animals and included regulations about becoming unclean from contact with such things. Therefore, items that were rendered unclean had to be purified in certain ways, including immersing them in water or destroying them if they were made of clay (vv. 24-25, 32, 33).
Through their rigorous interpretations, the Jewish legalists mandated that individuals wash their hands prior to meals to prevent any inadvertent transmission of uncleanness to the food, asserting that this precaution was necessary based on the "tradition of the elders" with its many intricate rules. This tradition, which later found its way into the Talmud, was evidently viewed as obligatory during Jesus’ time, as illustrated by the words of the evangelist Mark: “The Pharisees and all the Jews do not eat unless they wash their hands, holding to the tradition of the elders; and when they come from the marketplace, they do not eat unless they wash. And there are many other things which they have received in order to observe: the washing of cups, pitchers, and copper vessels” (7:3-4).
When the Pharisees and scribes observed some of Jesus’ disciples eating without washing their hands, they first confronted them, and then directed their inquiry to Jesus: “Why do Your disciples not live according to the tradition of the elders, but eat bread with unwashed hands?” The disciples' actions were not deliberate, as St. John Chrysostom notes, but stemmed from their disdain for what was excessive and their focus on fulfilling essential requirements.
