Said of Drink deeply of the Spirit:
"Halldorf's contribution to the understanding of the comforting and guiding power of the Holy Spirit is as important to the understanding of the Christian life as it is to theology."
- Werner Jeanrond in Svenska Dagbladet
"Peter Halldorf can really write. He knows his subject. He is well-read, generous - and he lets me discover my own paths in and out of the text's jungle. It is impressive."
- Kristian Lundberg in Norrköping's newspapers
“Drinking deeply of the Spirit unites the charismatic and contemplative dimension. This book is not only about the Spirit, it conveys the life of the Spirit.”
- Grethe Livbjerg in Catholic Orientation
