Explore the mystery of Christ’s Passion with readings, chant, and Jesus’ own prayer book, the Psalter. The Rev. Deacon Sam Tallman leads the Tenebrae service on Wednesday, April 4, at 6 p.m., which opens our observance of the three holy days of Maundy Thursday, Good Friday and the Vigil of Easter. Tenebrae is the Latin word for “darkness” or “shadows.”
