"Be who God meant you to be and you will set the world on fire."
So said St Catherine of Siena whose festival day this is. Marriage is intended to be a way in which man and woman help each other to become what God meant each one to be, their deepest and truest selves.
Many people are fearful for the future of today's world but the message of the celebrations in this country and far beyond its shores is the right one - this is a joyful day! It is good that people in every continent are able to share in these celebrations because this is, as every wedding day should be, a day of hope.
In a sense every wedding is a royal wedding with the bride and groom as king and queen of creation, making a new life together so that life can flow through them into the future.
William and Catherine, you have chosen to be married in the sight of a generous God who so loved the world that he gave himself to us in the person of Jesus Christ.
In the Spirit of this generous God, husband and wife are to give themselves to each other.
The spiritual life grows as love finds its centre beyond ourselves. Faithful and committed relationships offer a door into the mystery of spiritual life in which we discover this: the more we give of self, the richer we become in soul; the more we go beyond ourselves in love, the more we become our true selves and our spiritual beauty is more fully revealed. In marriage we are seeking to bring one another into fuller life.
