They should think on the many Gospel passages about the waters, like Christ calming troubled seas. The bishop encouraged Catholics to have "that same faith that Peter had" during the storms.
Among residents who have left town is the Corpus Christi diocese's chancellor, Benedict Nguyen. He and his wife have five children, age 10-21, one of whom is studying in Kansas.
"We assessed the situation, boarded up our house, and decided it would be best to go stay with the family a little bit," Nguyen told CNA from Kansas. "Just wait it out."
The diocese has been preparing for days in a very stressful situation.
"I think the most troubling thing is just the unpredictability of it," Nguyen continued. "We're not sure how expensive the damage will be. We know there will be some power outages, possibly some property damage, and of course it's not just the chancery office itself but all of the parishes."
"We have 70 parishes and 30 missions we have to think about also," he said, reporting that the chancery office itself is just two blocks from the bay.
"We're up on a little bit of a hill, on a high point right behind the cathedral," he said. "Our cathedral looks out towards downtown corpus Christi. Beyond that is the bay."
The storm protocols involve various planning for parish communications, data backups, keeping in touch with staff, and preservation of the diocesan archives. Individual parish churches have their own response plans.
"The first thing is always to keep God in mind, to pray. Family comes first, people come first. Things can always be replaced," the chancellor said.
At the same time, the diocese was aware of the need to take care for its patrimony.
Among the groups aiding victims of the storm is Catholic Charities of the Archdiocese of Galveston-Houston. It plans to meet emergency needs for shelter, food and medication for those who lose everything in the storm.
