This tour is being led by Msgr. Gregory A. Gier of The Cathedral of the Holy Family of Nazareth in Tulsa, Oklahoma. Click here or on the image for an online brochure.
This tour seems to be specifically for parishioners of the cathedral:
. . . parishioners are invited to join Msgr. Gier on an unforgettable pilgrimage to Turin to see the Shroud, then on to Florence, Assisi, Siena, and finally Rome. Msgr. Gier will offer Holy Mass daily at many of the important churches we will visit, including St. Peter’s Basilica in Rome. The dates are April 19 – 28, 2015.
