The prohibition of charging interest on loans is a significant theme in the biblical texts, reflecting the ethical and moral considerations of economic transactions among the Israelites. This principle is rooted in the broader biblical mandate to promote justice, compassion, and community solidarity.

Old Testament Foundations

The Old Testament provides several explicit instructions regarding the prohibition of interest, particularly in the context of lending to fellow Israelites. The Hebrew term often translated as "interest" is "neshekh," which implies a biting or usurious charge.

1. Exodus 22:25 : "If you lend money to one of My people among you who is poor, you must not be like a moneylender to him; you must not charge him interest." This verse underscores the importance of compassion and support for the economically disadvantaged within the community, emphasizing that lending should be an act of kindness rather than an opportunity for profit.

2. Leviticus 25:35-37 : "If your brother becomes impoverished and cannot support himself among you, help him as you would a foreigner or stranger, so that he can continue to live among you. Do not take any interest or profit from him, but fear your God, so that your countryman may continue to live among you. You must not lend him your money at interest or sell him your food at a profit." This passage highlights the responsibility of the Israelites to support their kin without exploiting their vulnerable situation, reinforcing the covenantal relationship among God's people.

3. Deuteronomy 23:19-20 : "Do not charge your brother interest on money, food, or any other type of loan. You may charge a foreigner interest, but you must not charge your brother interest, so that the LORD your God may bless you in everything to which you put your hand in the land you are entering to possess." Here, the distinction between Israelites and foreigners is made, with the prohibition specifically applied to fellow Israelites, reflecting the unique covenantal bond and the call to mutual care.

Wisdom Literature

The wisdom literature of the Old Testament also addresses the issue of interest, often associating it with righteousness and integrity.

· Proverbs 28:8 : "He who increases his wealth by interest and usury lays it up for one who is kind to the poor." This proverb suggests that wealth gained through interest is ultimately futile and will benefit those who are generous to the poor, aligning with the biblical theme of divine justice.

New Testament Context

While the New Testament does not explicitly reiterate the Old Testament laws on interest, the teachings of Jesus and the apostles emphasize principles of love, generosity, and selflessness, which align with the spirit of the Old Testament prohibitions.

· Luke 6:34-35 : "And if you lend to those from whom you expect repayment, what credit is that to you? Even sinners lend to sinners, expecting to be repaid in full. But love your enemies, do good to them, and lend to them, expecting nothing in return. Then your reward will be great, and you will be sons of the Most High; for He is kind to the ungrateful and wicked." Jesus' teaching here encourages a radical generosity that transcends conventional economic practices, reflecting the kingdom values of mercy and grace.

Historical and Theological Implications

The prohibition of interest on loans has been a topic of theological reflection and debate throughout Christian history. The early Church Fathers, such as Ambrose and Augustine, condemned usury, viewing it as contrary to Christian charity and justice. The medieval Church also upheld these prohibitions, although interpretations and applications have evolved over time.

In contemporary discussions, the biblical prohibition of interest challenges Christians to consider ethical financial practices and the impact of economic systems on the poor and marginalized. The enduring principle is one of fostering a community where resources are shared equitably, and the dignity of every person is upheld.
