Christian Ethics

Is charging interest on a loan morally wrong?

Christians disagree over whether biblical prohibitions of interest condemn charging for money as such, permit ordinary commercial lending while forbidding exploitation, or demand broader reform of debt systems that profit from vulnerability.

The question

Where the disagreement lies

Ancient loans often addressed subsistence rather than business investment, while modern finance distinguishes inflation, risk, opportunity cost, mortgages, credit, and predatory lending. The moral task is to relate those differences to Scripture’s protection of poor borrowers.
