I believe there is a mistaken understanding here. No deacon, priest or bishop makes vows of any kind.
Vow are proper to the consecrated life. Consecrated men and women are those who are: married, consecrated virgins, hermits and then there are those that belong to abbeys, religious orders, religious congregations, some secular orders, and secular institutes.
When a secular man is ordained a deacon he PROMISES not vows, obedience to the bishop and celibacy if he is not married. If he is married, he promises to remain celibate after the death of his wife. This is true for the 23 Catholic Churches.
If a man is a consecrated religious or a member of a society or secular institute that has made vows, this part of the ritual is skipped and the ceremony proceeds to the actual ordination.
As you can see, the vow of poverty is not part of the sacrament of Holy Orders. Therefore, a deacon, priest or bishop who is not a consecrated man (religious or other), but is strictly a secular man, can retain ownership of his assets and acquire more assets.
If Donald Trump’s son were to be ordained a priest and he inherits his father’s fortune, it is legally and justly his to keep and do with as he pleases.
If Donald Trump’s son is a consecrated religious (ordained or not), the rules of that institute apply.
If you belong to a religious order, you may not inherit your father’s fortune or keep what you had before entering. You must give it away before making perpetual vows and you must legally renounce your right to inherit.
If you belong to a religious congregation, you may inherit your father’s fortune and keep what you had before you entered, but you may not make use of it. You can put it aside for your identified heir after your death or you can give it to charity.
If you belong to a secular society, such as the SOLT, you can inherit, you can keep and you can use according to the constitutions of that society. Why? Because you are not a consecrated man. You are a secular person, unless the statutes of the society say that you must do X, Y or Z or the founder said that you must do X, Y or Z.
Poverty has nothing to do with the priesthood. It is part of the consecrated life (excluding marriage which is also a vowed life). While many priests are consecrated religious, not all of them are. Our current pope is a secular man. He owns property and has money of his own. I have no idea if he’s a wealthy man or not. I know that he and his brother own a home in Bavaria, that he was a professor who was paid a salary, a writer who was paid royalties, and the Prefect of the Sacred Congregation for the Faith who is paid a salary and benefits like any other Church employee. For all I know, he may have given it all away or it may all be in a bank account in his cat’s name. That’s his business.
We need to stay out of the financial affairs of our religious and clergy, just as we don’t want them in our financial affairs, unless we work for the IRS.
The only law that the Church imposes on the ordained is that they live a simple life, not a poor life. A simple life is a very broad term. What is luxury in one context can be very simple in another. Compare a $200,000.00 home in New York City to one in Omaha.
