Reply Obj. 3: A person to whom a spiritual power is entrusted is bound by virtue of his office to exercise the power entrusted to him in dispensing spiritual things. Moreover, he receives a statutory payment from the funds of the Church as a means of livelihood. Therefore, if he were to accept anything for the exercise of his spiritual power, this would imply, not a hiring of his labor (which he is bound to give, as a duty arising out of the office he has accepted), but a sale of the very use of a spiritual grace. For this reason it is unlawful for him to receive anything for any dispensing whatever, or for allowing someone else to take his duty, or for correcting his subjects, or for omitting to correct them. On the other hand it is lawful for him to receive "procurations," when he visits his subjects, not as a price for correcting them, but as a means of livelihood. He that is possessed of science, without having taken upon himself the obligation of using it for the benefit of others can lawfully receive a price for his learning or advice, since this is not a sale of truth or science, but a hiring of labor. If, on the other hand, he be so bound by virtue of his office, this would amount to a sale of the truth, and consequently he would sin grievously. For instance, those who in certain churches are appointed to instruct the clerics of that church and other poor persons, and are in receipt of an ecclesiastical benefice for so doing, are not allowed to receive anything in return, either for teaching, or for celebrating or omitting any feasts.
Reply Obj. 4: It is unlawful to exact or receive anything as price for entering a monastery: but, in the case of small monasteries, that are unable to support so many persons, it is lawful, while entrance to the monastery is free, to accept something for the support of those who are about to be received into the monastery, if its revenues are insufficient. In like manner it is lawful to be easier in admitting to a monastery a person who has proved his regard for that monastery by the generosity of his alms: just as, on the other hand, it is lawful to incite a person's regard for a monastery by means of temporal benefits, in order that he may thereby be induced to enter the monastery; although it is unlawful to agree to give or receive something for entrance into a monastery (I, qu. ii, cap. Quam pio). _______________________
FOURTH ARTICLE [II-II, Q. 100, Art. 4]
Whether It Is Lawful to Receive Money for Things Annexed to Spiritual
Things?
Objection 1: It would seem lawful to receive money for things annexed to spiritual things. Seemingly all temporal things are annexed to spiritual things, since temporal things ought to be sought for the sake of spiritual things. If, therefore, it is unlawful to sell what is annexed to spiritual things, it will be unlawful to sell anything temporal, and this is clearly false.
Obj. 2: Further, nothing would seem to be more annexed to spiritual things than consecrated vessels. Yet it is lawful to sell a chalice for the ransom of prisoners, according to Ambrose (De Offic. ii, 28). Therefore it is lawful to sell things annexed to spiritual things.
Obj. 3: Further, things annexed to spiritual things include right of burial, right of patronage, and, according to ancient writers, right of the first-born (because before the Lord the first-born exercised the priestly office), and the right to receive tithes. Now Abraham bought from Ephron a double cave for a burying-place (Gen. 23:8, sqq.), and Jacob bought from Esau the right of the first-born (Gen. 25:31, sqq.). Again the right of patronage is transferred with the property sold, and is granted "in fee." Tithes are granted to certain soldiers, and can be redeemed. Prelates also at times retain for themselves the revenues of prebends of which they have the presentation, although a prebend is something annexed to a spiritual thing. Therefore it is lawful to sell things annexed to spiritual things.
On the contrary, Pope Paschal [*Paschal II] says (cf. I, qu. iii, cap. Si quis objecerit): "Whoever sells one of two such things, that the one is unproductive without the other, leaves neither unsold. Wherefore let no person sell a church, or a prebend, or anything ecclesiastical."
I answer that, A thing may be annexed to spiritual things in two ways. First, as being dependent on spiritual things. Thus to have ecclesiastical benefices is said to be annexed to spiritual things, because it is not competent save to those who hold a clerical office. Hence such things can by no means exist apart from spiritual things. Consequently it is altogether unlawful to sell such things, because the sale thereof implies the sale of things spiritual. Other things are annexed to spiritual things through being directed thereto, for instance the right of patronage, which is directed to the presentation of clerics to ecclesiastical benefices; and sacred vessels, which are directed to the use of the sacraments. Wherefore such things as these do not presuppose spiritual things, but precede them in the order of time. Hence in a way they can be sold, but not as annexed to spiritual things.
Reply Obj. 1: All things temporal are annexed to spiritual things, as to their end, wherefore it is lawful to sell temporal things, but their relation to spiritual things cannot be the matter of a lawful sale.
