Whether it is lawful to give and receive money for spiritual actions?

Objections

Objection 1 : It seems that it is lawful to give and receive money for spiritual actions. The use of prophecy is a spiritual action. But something used to be given of old for the use of prophecy, as appears from 1 Kgs. 9:7,8, and 3 Kgs. 14:3. Therefore it would seem that it is lawful to give and receive money for a spiritual action.
Objection 2 : Further, prayer, preaching, divine praise, are most spiritual actions. Now money is given to holy persons in order to obtain the assistance of their prayers, according to Lk. 16:9, "Make unto you friends of the mammon of iniquity." To preachers also, who sow spiritual things, temporal things are due according to the Apostle (1 Cor. 9:14). Moreover, something is given to those who celebrate the divine praises in the ecclesiastical office, and make processions: and sometimes an annual income is assigned to them. Therefore it is lawful to receive something for spiritual actions.
Objection 3 : Further, science is no less spiritual than power. Now it is lawful to receive money for the use of science: thus a lawyer may sell his just advocacy, a physician his advice for health, and a master the exercise of his teaching. Therefore in like manner it would seem lawful for a prelate to receive something for the use of his spiritual power, for instance, for correction, dispensation, and so forth.
Objection 4 : Further, religion is the state of spiritual perfection. Now in certain monasteries something is demanded from those who are received there. Therefore it is lawful to demand something for spiritual things.
