In 2002 the Church selected St. Isidore of Seville to be the official patron of computer programmers.
Write a simple letter laying out the reasons why a particular saint would be a good patron for a profession, industry, or hobby and find co-signatories. Then begin sending your letter to Rome. In a big institution there are lots of doors and you should knock on all of them repeatedly. As appropriate try:
- Pontifical Council for the Laity: www.laici.va
- Pontifical Council for the Family: www.familia.va
- Pontifical Council for Culture: www.cultura.va
- Pontifical Council for Social Communications: www.pccs.va
- The Pontifical Council for Promoting the New Evangelization Year of Faith: www.annusfidei.va
- Pontifical Academy of Sciences: www.casinapioiv.va
- Pontifical Academy of Social Sciences: www.pass.va
- Congregation for the Causes of Saints: http://www.vatican.va/roman_curia/congregations/csaints/
Also write to your bishop's office.
As for a place to find cosignatories, you might try a place where likeminded folks are likely to be present. I work in IT and know what you mean - there aren't that many Christians running around, and few of us are Catholic. But where is the intersection? Set logic:
Catholic /\ IT = IT workers at Catholic institutions?
Try canvassing computer science departments, IT and IS departments, and so on at local Catholic schools, hospitals, Catholic Charities, etc. Contact them with a brief intro to gauge interest.
Maybe build an online petition they can sign and submit it, with all due respect, to the possibly relevant departments. Make noise. And be patient. Nothing moves quickly in Rome.
But then, since computer scientists already have at least one patron saint, maybe we're all cool.
St. Isidore of Seville, pray for us.
