Christian Denominations: How They Differ on Charging Interest to Friends
Catholic Church
Charging a friend in genuine need exploitative interest is sinful; a modest agreed rate in a business-like loan between peers is ordinarily venial at most.
Catechism of the Catholic Church
Protestant Churches
Protestants split between accepting normal commercial rates and recovering the older free-loan ethic (Luke 6:35), especially among friends.
Holy Bible (Protestant canon)
Eastern Orthodox
Orthodox canon law historically condemned usury, including among clergy; modern practice condemns exploitation while tolerating ordinary bank rates.

Christianity began with the Bible's sharpest anti-interest texts. The Torah forbade interest to the poor (Exodus 22:25), Psalm 15 praised the man who 'does not put out his money at interest,' and Jesus raised the bar again: 'lend, expecting nothing in return' (Luke 6:35). For most of church history this was read as a near-blanket ban — Dante parked usurers in the same circle of the Inferno as the violent. The shift came as commerce demanded capital: scholastics distinguished predatory usury (always sin) from moderate, time-valued interest on productive loans (permitted), and Catholic teaching since has held that line — interest is licit when proportionate, exploitative when it weaponizes someone's necessity (a point the Catechism's economic-justice teaching, 2436, reinforces). Between friends the older ideal resurfaces: a friend asking for a loan is usually in need, and need is exactly the case the biblical texts protect. Most Protestant ethicists say the same with less apparatus: a real friend gets either a gift, a free loan with clear terms, or a business deal honestly labeled.

- Write the terms down even between friends — clarity protects the friendship more than a handshake does.
- If a friend is in genuine need, prefer a gift, a free loan, or co-signed help over an interest arrangement.
- Christian: Hold Luke 6:35 as the friend-standard — 'lend, expecting nothing in return' — and treat any interest as a business deal, honestly labeled.
- All: If a loan has already strained a friendship, renegotiate forgiveness or repayment terms before you lose both the money and the friend.

This is where traditions genuinely diverge.
This is where traditions genuinely diverge. Christianity permits modest agreed rates, though many counsel free loans whenever need is involved.
What if we both just think of it as a business deal?
Labeling helps morally — honesty about the nature of the arrangement matters — but it does not override the religious rules.
