"Holy Thursday solemnly inaugurates 'the triduum during which the Lord died, was buried and rose again' (St. Augustine). To these days Jesus referred when he prophesied: 'Destroy this temple and in three days I will raise it up again' (John 2:14)."   --"The Sacred Paschal Triduum," "Celebrating the Eucharist: February 17, 2021 - April 24, 2021" [missalette], p. 156.
