It goes without saying that it is never permitted to receive even the least recompense for preaching, or the administration of the sacraments, or any other ministry.
1818 Rule Part 1, Chapter 3, §1 Preaching
The Missionary co-operator of the Savior must imitate the example of the apostles:
“Give as freely as you have received! Don’t take any money in your money belts– no gold, silver, or even copper coins. Don’t carry a traveler’s bag with a change of clothes and sandals or even a walking stick. Don’t hesitate to accept hospitality, because those who work deserve to be fed.”
“There is always the danger that we may just do the work for the sake of the work. This is where the respect and the love and the devotion come in – that we do it to God, to Christ, and that’s why we try to do it as beautifully as possible.” Mother Teresa
