Yesterday was Ash Wednesday, the beginning of Lent. A few useful links:
Praying Lent 2010 from Creighton University.
The Spiritual Exercises Blog, follow meditations based on the Spiritual Exercises of St. Ignatius of Loyola during Lent.
Aggie Catholics Annual Lenten Megapost plus Compulsory Ash Wednesday Reading and Viewing from the same blog. A day late but oh, well.
A Comprehensive Guide to Lent: History, Resources, Links, and FAQ from ChurchYear.Net including their fine Church Fathers Lenten Reading Plan.
This plan is included in the Fr. Jerabek's Lenten Reading Plans page along with ones dedicated to the saints, to Fr. Faber and Cardinal Newman, and to St. Jean Marie Vianney.
This blogger links to a plan based on the writings of St. John Climacus, Thoughts on the Ladder of Divine Ascent, as well as a sermon by Metropolitan Jonah of the Orthodox Church in America.
