One of the important aspects of the liturgical life of the Church relates to the celebration of Saints’ Days in the Calendar. You might be aware that the 29^th September is Michaelmas, but most people do not know why the feast is celebrated on that day. The date refers to the dedication of a church in Rome under St Michael’s patronage, which was dedicated on that day in the fifth century. Likewise, the Church of the Holy Sepulchre in Jerusalem, the site of Our Lord’s Crucifixion and Resurrection, was built under orders from the Roman Emperor Constantine and dedicated on the 13^th September 335ad. On the following day, the 14^th September, the True Cross, which his mother, St Helena, had discovered in 326AD, was brought out for the Christian faithful to venerate. The feast day also commemorates the exaltation of the Holy Cross in Constantinople in 629AD, when the True Cross was returned by the Persians, who had taken it during the sack of Jerusalem some fifteen years earlier. 

That is why we celebrate the Holy Cross today. But what are we celebrating? The Cross of Christ. The fact that God loves humanity enough to suffer and die for us, to take away our sins, and to offer us eternal life with God forever. This is the central truth of our faith, a life-changing reality which affects both this life and the next. The Holy Cross changes the world. We are freed and saved by the Cross.

In this morning’s Gospel, Our Lord is explaining His mission to Nicodemus:

“Ac fel y dyrchafodd Moses y sarff yn yr anialwch, felly y mae’n rhaid i Fab y Dyn gael ei ddyrchafu, er mwyn i bob un sy’n credu gael bywyd tragwyddol ynddo ef.”

‘And as Moses lifted up the serpent in the wilderness, so must the Son of Man be lifted up, that whoever believes in him may have eternal life.’ (Jn 3:14-15)

Jesus is drawing a parallel between His death and a significant event in the Exodus story, which is this morning’s Old Testament reading. Once again the people of Israel are complaining about the food and conditions on their journey: 

“Pam y daethoch â ni o’r Aifft i farw yn yr anialwch? Nid oes yma na bwyd na diod, ac y mae’n gas gennym y bwyd gwael hwn.”

‘Why have you brought us up out of Egypt to die in the wilderness? For there is no food and no water, and we loathe this worthless food.’ (Num 21:5)

The Israelites are rejecting the manna, bread given from Heaven, a gift from God. In response, God sends snakes which kill them. This causes the people to realise their sin, and repent. They ask Moses to intercede for them with the Almighty, and Moses is instructed to do the following:

“Gwna sarff a’i gosod ar bolyn, a bydd pawb a frathwyd, o edrych arni, yn cael byw.”

‘Make a fiery serpent and set it on a pole, and everyone who is bitten, when he sees it, shall live.’ (Num 21:8)

God does not take the serpents away, but He does give healing, and life. The Exodus story points to Christ, the Saviour and giver of life. In the Gospel, Jesus is explaining the Crucifixion to Nicodemus, to help him begin to understand how God is giving life to humanity. Our Lord points out what causes death, and what will now bring life. 

Just as the serpent in the desert brought healing to the people of Israel, so now the Cross is our only hope. The sacrifice of God for humanity is a free gift of infinite value. God gives salvation to us, and to all the world, for one simple reason: because He loves us, and desires that we might become more lovely, more like Him. God sends His Son into the world not to condemn it, but so that the world might be saved through Him. This is an unselfish act of generosity, of grace, by our Maker so that we might be saved from sin and death, from ourselves, and so that we can share new life in Him.

‘Do, carodd Duw y byd gymaint nes iddo roi ei unig Fab, er mwyn i bob un sy’n credu ynddo ef beidio â mynd i ddistryw ond cael bywyd tragwyddol. Oherwydd nid i gondemnio’r byd yr anfonodd Duw ei Fab i’r byd, ond er mwyn i’r byd gael ei achub trwyddo ef.’

‘For God so loved the world, that he gave his only Son, that whoever believes in him should not perish but have eternal life. For God did not send his Son into the world to condemn the world, but in order that the world might be saved through him.’ (Jn 3:16-17)

These few words spoken by Jesus to Nicodemus, recorded in John’s Gospel, encapsulate what we believe as Christians, and why we believe these things. Strengthened through prayer, our study of the Bible, nourished by Our Lord’s Body and Blood, may we live out our beliefs, forgiven and forgiving, preparing to be caught up forever in the love of God. Christ liberates us from sin and death. He saves us so that we may enjoy eternal life with God. Our response to such generosity should be thankfulness: that we are loved by God, and saved by Him.

Jesus’ sacrifice on the Cross is the same sacrifice which we see here this morning, which we can taste and touch. Bread and Wine, The Body and Blood of Our Lord which we can eat and drink, so that our lives and our souls can be transformed to live Christ’s risen life. We treat these elements with the uttermost reverence because they are God, given for us. They transform us to live as children of the Holy Spirit, freed from the shackles of this world. They strengthen us to live for God, to live as He wants us to, as His new creation. On a hundred thousand successive Sundays Christians have participated in this sacrifice, in memory of Him, to make the holy people of God. We likewise do this to make us holy: so that everything which we say, or think, or do, may be for God’s praise and glory.

Let us, therefore, give thanks for the fact that God loves us. Let us cling to the Cross, and let us sing the praises of God, Duw Dad, Duw y Mab, a Duw yr Ysbryd Glân. God the Father, God the Son, and God the Holy Spirit. I’r hwn y priodoler pob gogoniant, arglwyddiaeth, a gallu, yn awr, ac yn oes oesoedd. To whom be ascribed all glory, dominion and power, now and forever. Amen
