On all but three Sunday afternoons since last Easter, Bob Guerra — a Catholic deacon — has carefully packed his favorite crucifix, a Spanish-language Bible, hundreds of Communion wafers secured in Ziploc bags and other liturgical items into a plastic storage box.
Then he lugs it a few miles to Fort Bliss, an Army base in the desert on the outskirts of El Paso, where he helps celebrate Mass for hundreds of migrant teens held at a vast tent shelter.
