When I was a kid in the Catholic church I remember that the priests and nuns took a vow of poverty. That is they put their obedience to God above monetary gain. That seemed like a noble thing to me. Of course I have come to realize that this vow of poverty did not mean that the Catholic clergy lived a lifestyle of the poor around them. They were provided a handsome house with a housekeeper/ cook to provide for them and when they retired there was a rather comfortable living arrangement for them to live out their lives.
A vow of poverty was just not the same as living in poverty. Even that being the case they are giving up much of the luxuries that are common in this world. I do admire them for that. I’m not sure if this vow is exclusively Catholic or if other denominations follow suit. I do know that the clergyman of the Lutheran church which I used to belong to was very well compensated for his efforts. His salary and benefits exceeded most in the congregation he served.
Maybe that is one of the problems that churches have when it comes to ministering to the poor. Many just have no idea what being poor is really about. A vow of poverty kind of makes sense for those who are teaching us that we are only visitors in the world and that our true home is in the next.
