Judaism Jews are forbidden from usury in dealing with fellow Jews, and this lending is to be considered
tzedakah, or charity. However, there are permissions to charge interest on loans to
non-Jews. Several historical rulings in
Jewish law have mitigated the allowances for usury toward non-Jews. For instance, the 15th-century commentator
Rabbi Isaac Abrabanel specified that the rubric for allowing interest does not apply to Christians or Muslims, because their faith systems have a common ethical basis originating from Judaism. The medieval commentator
Rabbi David Kimchi extended this principle to non-Jews who show consideration for Jews, saying they should be treated with the same consideration when they borrow.
Islam The following quotations are English translations from the
Qur'an: The attitude of Muhammad to usury is articulated in his Last Sermon:
Christianity The
Old Testament "condemns the practice of charging interest because a loan should be an act of compassion and taking care of one's neighbor"; it teaches that "making a profit off a loan is exploiting that person and dishonoring God's covenant (Exodus 22:25–27)". The first of the
scholastic Christian theologians,
Saint Anselm of Canterbury, led the shift in thought that labeled charging interest the same as theft. St.
Thomas Aquinas, the leading scholastic theologian of the
Roman Catholic Church, argued charging of interest is wrong because it amounts to "double charging", charging for both the thing and the use of the thing. Outlawing usury did not prevent investment, but stipulated that in order for the investor to share in the profit he must share the risk. In short he must be a joint-venturer. Simply to invest the money and expect it to be returned regardless of the success of the venture was to make money simply by having money and not by taking any risk or by doing any work or by any effort or sacrifice at all, which is usury. Thus a banker or credit-lender could charge for such actual work or effort as he did carry out, for example, any fair administrative charges. The Catholic Church, in a decree of the
Fifth Council of the Lateran, expressly allowed such charges in respect of credit-unions run for the benefit of the poor known as "
montes pietatis". In the 13th century
Cardinal Hostiensis enumerated thirteen situations in which charging interest was not immoral. The most important of these was
lucrum cessans (profits given up) which allowed for the lender to charge interest "to compensate him for profit foregone in investing the money himself". This idea is very similar to opportunity cost. Many scholastic thinkers who argued for a ban on interest charges also argued for the legitimacy of
lucrum cessans profits (for example,
Pierre Jean Olivi and
St. Bernardino of Siena). However, Hostiensis' exceptions, including for
lucrum cessans, were never accepted as official by the Roman Catholic Church. The
Westminster Confession of Faith, a confession of faith upheld by the
Reformed Churches, teaches that usury — defined as charging interest at any rate — is a
sin prohibited by the
eighth commandment. The Roman Catholic Church has always condemned usury, but in modern times, with the rise of capitalism and the disestablishment of the Catholic Church in majority Catholic countries, this prohibition on usury has not been enforced. The
Congregation of the Missionary Sons of the Immaculate Heart of Mary, a Catholic Christian
religious order, teaches that: ==Notes==
