Stations of the King's Cross. According to the project's website, the artist "has found idle train trips an amazingly fruitful time for prayer & contemplation".
The Catholic Herald quotes the artist:
It would be great if the wonder of the human imagination was acknowledged and encouraged more within the Church. Read the letter of His Holiness Pope John Paul II to Artists . He has such clear ideas about the importance of art to human society. [As he says] ‘The human craftsman mirrors the image of God as Creator’.
It is a strikingly beautiful and meaningful way of encouraging Christians to reflect on the way of the Cross in the midst of a 21st century city - and a model of of how the Tradition, art and imagination can wonderfully combine to serve the new evangelisation.
(While the artist invites readers of the website to ask for a free book of the Stations of the King's Cross, as of this afternoon there are few copies left. A good sign!)
