§ V. On Refuge
A receiver, or one providing refuge, is he who knowingly and freely provides security to a robber or another damager. Concerning him these things must be established:
1st. One receiving is held for damages coming from his manner of acting. For one providing security efficaciously and unjustly determines the will of the thief, or makes it firmer, in the purpose either of stealing or of not restoring or of stealing again.
2nd. Likewise merchants and especially innkeepers are held to restitution who accept stolen goods of sons of families, servants, etc., or hide them, or even claim them for themselves as the price of merchandise, drinking-bouts, etc.
3rd. Among those receiving are not to be reckoned those who receive at home friends or blood-relatives who are evildoers; nor those who hide them under hope of amendment, or show them the way by which they can flee, when they are sought for prison or for death. Cf. St. Alphonsus, n. 568.
