The serpent lifted up in the desert is a symbol of Christ who was raised up on the cross to save all of humanity by his Sacrifice. The Lord said to Moses: “Make a saraph and mount it on a pole and if anyone who has been bitten looks at it, he will recover” (Num 21,8). In the Gospel Jesus says: “As Moses lifted up the serpent in the wilderness, even so must the Son of Man be lifted up, so that whoever believes in him will have eternal life” (Jn 3,14-15). 50
