I like this quote from the Bishop of London’s sermon for the Royal Wedding.
A 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.
