In particular:
- Spiritual Classics (ed. Richard J. Foster & Emilie Griffin)
- Devotional Classics (ed. Richard J. Foster & James Bryan Smith)
(mind you, the above are just anthologies of excerpts, and Logos should really include the full text of the originals those are sourcing from, if it doesn't already; but...they are great invitations into to those fuller texts which otherwise might be overwhelming to many people: Hildegard of Bingen, Julian of Norwich, Catherine of Sienna, Thomas à Kempis, and many more)
By Richard Foster:
- Prayer: Finding the Heart's True Home
- Celebration of Discipline
- Freedom of Simplicity
- Streams of Living Water
