Whether it is lawful to receive money for things annexed to spiritual things?

Objections

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.
Objection 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.
Objection 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 (Gn. 23:8, sqq.), and Jacob bought from Esau the right of the first-born (Gn. 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.
