"Come, Holy Spirit"
The Holy Spirit, whose anointing permeates our whole being, is the interior Master of Christian prayer. He is the artisan of the living tradition of prayer. To be sure, there are as many paths of prayer as there are persons who pray, but it is the same Spirit acting in all and with all. It is in the communion of the Holy Spirit that Christian prayer is prayer in the Church.
