So, according to the Book of Common Prayer, Lent is a season in which all Christians are invited "to the observance of a holy Lent, by self-examination and repentance; by prayer, fasting, and self-denial; and by reading and meditating on God's holy Word" (BCP, p. 265). Traditionally, Lent is a time when we deny ourselves something that is good to do without (sweets, alcohol, carbs, etc.); we add something into our daily routines that is good for us (reading the Bible, exercising, keeping a journal, etc.); and focusing time that used to be spent on other things on prayer and meditation, studying and growing our spiritual lives into something we would like it to be.
There are many options out there for Episcopals. Here are a few favorites:
Society of St. John the Evangelist - Growing a Rule of Life:
Walk the Path of Lent - the Episcopal Relief and Developments daily meditations.
The Crucified Life - from the Christian Life Trilogy.
Lent Madness - a fun way to learn about the saints, early church fathers and mothers.
I Am With You - The Archbishop of Canterbury's Lent 2016 readings.
