Chapter 19 — Part II: The Sacraments — Penance
Section 171. Restitution Must Be Insisted On — Above all, priests should be very careful not to give absolution to any penitent, whose confession they have heard, without obliging him to make full satisfaction for any injury to his neighbour's goods or character for which he seems responsible. No person is to be absolved until he has first faithfully promised to restore all that belongs to others.
