Celebration of Discipline: The Path to Spiritual Growth is a classic spiritual formation book first written back in 1978 by Richard J. Foster (no relation). He covers a lot of territory about what Christian practice is, different disciplines, and how we can use them in our lives every day. Foster has updated a “40th Anniversary” edition published 5 years ago almost to the day.
Assorted muttering and armchair theology from the interim pastor, Rev. Scott Foster.
