It would not look edifying for any priest to be wearing an Armani suit, a rolex and driving a luxury car regardless of where there parish might be (as the old joke goes, religious priests take the vow of poverty but diocesan priests live it). As far as priests on the Net go, I’m not aware of any who I’d say are exactly in trade or running a business (as opposed to a not-for-profit) but there are certainly some with Amazon search boxes or who solicit donations of money and/or goods. While not strictly prohibited, IMHO this whole “give me stuff because I’m a priest” thing doesn’t exactly fit well with the clerical state.
