The Trinity Foundation, which monitors religious fraud, has a project called “Pastr Planes” where they track the use of private jets by mega-church pastors, “ministry executives,” and staff of Christian universities.
As far as I know, the best you can do as a Unitarian Universalist minister is to get a plane ticket paid for under an IRS-approved accountable reimbursement plan (often incorrectly called “professional expenses”). I guess I’m in the wrong religion.
On the other hand, flying coach is sinfully bad for the environment. Flying in a private jet, therefore, is a super huge mega-sin. I would not want to be them when the Last Judgement (or whatever their theology calls for) comes and they are called to account for their sinning.
