Today is a day when we do nothing. For those whose tradition takes them through a detailed re-enactment of the events of Passion Week, the seven days set out in the gospels (especially Mark), this day is striking in its stillness. In Catholic tradition, nothing can be celebrated, the only exception being in the case of the ministry at the moment of death. In the mostly Catholic Philippines, you are traditionally not allowed to go swimming (though a concession has been made for Saturday afternoon) and even television broadcasters limit their output.
All this is in response to the stark silence of the gospel accounts for this day. Mark’s gospel mentions it only in retrospect (‘When the Sabbath was over…’ Mark 16.1). In Matthew, it is the day when the temple guard is despatched to the tomb, but nothing else happens (Matt 27.62–66). Luke explains for the sake of any non-Jewish readers the obligation to rest on the Sabbath, thus accounting for the silent day (Luke 23.56). John also includes a work (‘Jewish’) of explanation, but doesn’t actually tell us what he is explaining (not mentioning the Sabbath; John 19.42).
