Maundy Thursday Service of Tenebrae A quiet and reflective worship service, Maundy Thursday is the celebration of "the first Last Supper." The traditional name Tenebrae means "shadows," and this candlelight service takes place as the sun sets, casting long shadows while we share scripture readings and hymns telling the story of the final days leading up to Jesus's crucifixion. Communion will be served, and the table is open to all.
