For those who deal with sacred music, one of the problems that often arises is that of money.
There's no denying that sometimes money is necessary, but pointing out this fact hardly seems like that has to be kept hidden and the well-fed pious priest always happens to reproach you with a (falsely) seraphic smile that things must be done "in a spirit of gratuitousness".
This spirit, obviously, applies only to the Church musician and not to the others, who are (rightly) paid for their services for the liturgy and in the liturgy.
Now, we must not treat the liturgy as if it were a business, as it sometimes seems to me to be done in the American world. This is a serious mistake. We certainly cannot reduce the liturgy to a question of money, but we must accept a very simple and very logical fact: without money we cannot celebrate the liturgy properly.
Because the liturgy includes expenses such as those for electricity, amplification, liturgical vestments and so on. These things cannot be "stolen", but must be fairly paid to those who produce them. The same priest receives a certain amount for each Mass celebrated and the same should be the case for those who serve in sacred music, obviously in a professional way.
These ideas about doing things for free that seem very spiritual are actually not and, what's worse, they are also false. Even Jesus certainly needed money to support his preaching but he certainly wasn't trying to get rich with it.
We must use common sense to accept a fact that seems so obvious as that the liturgy also needs financial means to function well. Let's not try to make people believe that money is the problem. Money is not a problem, but the use we make of it can be. If money serves our good purposes then it is useful, but if we become servants of money, this becomes a real perversion.
