"On Good Friday, the entire Church fixes her gaze on the Cross at Calvary. Each member of the Church tries to understand at what cost Christ has won our redemption." - www.catholic.org
If you are like me and unable to get to Church today here is a link to the Via Crucis, the Way of the Cross by St. Alphonsus Liguori, read by Fr. John Zuhlsdorf. I find it helpful to see representations while praying, so here is another link to The Stations of the Cross that has beautiful images accompanying the meditations.
And over at Kristen's blog you can find today's Gospel reading, John 18:1 - 19:42
