Holy Eucharist, Rite II
Mark's Gospel refers first to the serpent-cum-staff that Moses raised up in the wilderness (Numbers 21) as the precursor of Jesus' being lifted up to give all of us eternal life. This passage includes John 3:16 (which fits nicely on signs at sporting events), with which many Christians are both familiar and from which we receive much comfort.
