The Third Lateran Council and later canon law forbade Christians from lending money at interest, which the Church called the sin of usury.

1179 The Church forbids Christians to lend at interest 0 cit. The Third Lateran Council rules that Christians who lend money at interest are guilty of the sin of usury and may be denied a Christian burial.
