It is the Holy Spirit who is the river of peace, the torrent of wealth, the river of gladness, the flowing stream of delight, and the abundance of God’s house. For he is himself the love that unites bride and Bridegroom in the city of glory and constitutes the entire happiness of all who live there. That love which is the Holy Spirit is the life of the holy angels and of all saintly souls.
–Rupert of Deutz (1075-1130)
