Rite and Reason: It was probably the most intimate public gathering Pope John Paul II had addressed for a long time and, as with Clonmacnois, which he had enjoyed so much, it was a monastic setting.
The service he conducted at St Catherine's monastery near the foot of Mount Sinai in Egypt was attended by just a few hundred people. It was accompanied throughout by the wails of children and audible conversation at the back, such as would accompany a similar event in many a parish church.
But it was his homily in that sublime setting, as petals from a blossoming tree showered upon him, which was most striking. It explained his understanding of God.
He said: "Today, with great joy and deep emotion, the Bishop of Rome is a pilgrim to Mount Sinai, drawn by this holy mountain which rises like a soaring monument to what God revealed here. Here he revealed his name. Here he gave his law, the Ten Commandments of the Covenant."
He continued: "God shows himself in mysterious ways - as the fire that does not consume - according to a logic which defies all that we know and expect. He is the God who is at once close at hand and far away; he is in the world but not of it.
"He is the God who comes to meet us, but will not be possessed. He is I am who I am [his emphasis] - the name which is no name. I am who I am: the divine abyss in which essence and existence are one. The God who is being itself. Before such a mystery, how can we fail to 'take off our shoes', as he commands, and adore him on this holy ground?"
He said: "The encounter of God and Moses on this mountain enshrines at the heart of our religion the mystery of liberating obedience, which finds its fulfilment in the perfect obedience of Christ in the incarnation and on the cross. We, too, shall be truly free if we learn to obey as Jesus did.
"The Ten Commandments are not an arbitrary imposition of a tyrannical Lord. They were written in stone; but before that they were written on the human heart as the universal moral law, valid in every time and place. Today, as always, the Ten Words of the Law provide the only true basis for the lives of individuals, societies and nations.
"Today, as always, they are the only future of the human family. They save man from the destructive force of egotism, hatred and falsehood. They point out all the false gods that draw him into slavery: the love of self to the exclusion of God, the greed for power and pleasure that overturns the order of justice and degrades our human dignity and that of our neighbour.
"If we turn from these false gods and follow the God who sets his people free and remains always with them, then we shall emerge like Moses, after 40 days on the mountain, 'shining with glory', ablaze with the light of God.
"To keep the commandments is be faithful to God but it is also to be faithful to ourselves, to our true nature and our deepest aspirations. The wind which still today blows from Sinai reminds us that God wants to be honoured in and through the growth of his creatures: Gloria Dei, homo vivens.
"In this sense, that wind carries an insistent invitation to dialogue between the followers of the great monotheistic religions in their service of the human family. It suggests that in God we can find the point of our encounter: in God the all powerful and all merciful, Creator of the universe and Lord of history; who, at the end of our earthly existence, will judge us with perfect justice."
He said: "Sinai finds its fulfilment on another mountain, the mountain of the Transfiguration, where Jesus appears to his apostles shining with the glory of God. Moses and Elijah stand with him to testify that the fullness of God's revelation is found in the glorified Christ.
"On the mountain of the Transfiguration, God speaks from the cloud as he had done on Sinai. But now he says: 'This is my beloved Son; listen to him.' He commands us to listen to his Son because 'no one knows the Father except the Son and anyone to whom the Son chooses to reveal him'.
"And so we learn that the true name of God is Father [his emphasis]. The name which is beyond all other names: Abba. And in Jesus we learn that our true name is Son, Daughter. We learn that the God of the Exodus and the Covenant sets his people free because they are his sons and daughters, created not for slavery but for 'the glorious liberty of the children of God'. So when St Paul writes that we 'have died to the law through the body of Christ', he does not mean that the law of Sinai is past. He means that the Ten Commandments now make themselves heard through the voice of the beloved Son.
"The person delivered by Jesus Christ into true freedom is aware of being bound not externally by a multitude of prescriptions, but internally by the love which has taken hold in the deepest recesses of his heart."
