Restitution in moral theology and soteriology signifies an act of commutative justice by which exact reparation as far as possible is made for an injury that has been done to another.[1] In the teaching of certain Christian denominations, restitution is an essential part in salvation.[2]
The salvation of the soul depends on the forgiveness of sins, which is absolutely impossible without restitution, if it can in any way be made. St. Anthony says: "He that is in possession of another's goods, and can make restitution, and does not do so, cannot obtain forgiveness, though he may do all possible works of penance. He may pray, fast, and give alms. All is in vain."
