I’m sure many of you have had this experience: you’re visiting a church that’s a little different than what you’re used to and the time for the Lord’s Prayer comes. Things are going pretty well until… boom! They ask God to forgive them their “debts” instead of “trespasses (or “trespasses” instead of “debts”—you get the idea). What gives? Why are there two different words that churches might use in that part of the Lord’s Prayer?

The most common answer I’ve heard was that it’s because the Lord’s Prayer appears in the Bible twice: once in Matthew 6:9-13 and once in Luke 11:2-4. What a delightful, satisfying little answer… until I actually looked those scriptures up and realized that NEITHER of them says “trespasses” anywhere. Matthew’s version says “debts” both times, even if you take it back to the original Greek! The root word for debt and debtors, opheilō, is what you’ll see in both instances. Forgive us our debts (opheilēmata) as we forgive our debtors (opheiletais). Luke’s version is definitely a little different, but not because it says trespasses. Jesus asks God to forgive us our sins (hamartias in Greek) as we forgive those who are indebted to us (opheilonti). So what gives? If the Bible uses “debts” three of the four instances, how on Earth did we end up with trespasses?

I tried to look for the oldest version of the Bible I could find that used some form of “trespasses” instead of “debts,” and I’m pretty confident that the furthest back you can get is the 1526 Tyndale Bible, one of the earliest and most influential Bibles in the English language. He was translating from Erasmus’s 1522 edition of the New Testament, which had both Greek and Latin text to work from. The Greek (which he was primarily working with) has the same words that we already looked at (debt, debtors, people indebted to us), and even if we glance at the Latin, the words are pretty debt-centric (“remittimus omni debenti“— release us from our debts, in Matthew 6:12, for instance). But when we look at Tyndale’s translation, you can see trespasses and trespassers for the first time! Why did he do that? Who knows? Nobody else was doing it. Maybe he was inspired by what Jesus said just after the Lord’s Prayer in Matthew 6:14-15, in which Jesus warns people that God will forgive their trespasses (paraptōmata) as they forgive the trespasses of others, but we can’t know for certain.

But how did Tyndale’s translation get so popular? Because it was used in the 1549 Book of Common Prayer, which is the official book of liturgy for the Church of England. At the time, his translation was one of the most readily available editions that came from the Greek. Over time, other English translations didn’t follow Tyndale’s direction on those verses, but the Book of Common Prayer kept it that way. In every service across the Church of England, that’s what people said, and as with all repeated pieces of liturgy, that’s how it stuck. As time went on, the influence of the Book of Common Prayer was felt in other denominations. Churches that make use of formal liturgy are more likely to say “trespasses” (Anglican, Methodist, Catholic, Lutheran, Eastern Orthodox), while churches that don’t use that same kind of formal liturgy are more likely to say “debts” (Presbyterian, Reformed, Baptist).

Which is probably the better translation? Debts. Obviously debts. It’s not even a question. That said, I doubt it would be a major grievance in Jesus’s eyes if you said trespasses instead. That’s how he described sins and forgiveness immediately after saying the Lord’s Prayer, so I can’t imagine him disapproving too much.

For those that want to go further, if you want to look at the Greek for yourself, the interlinear translation on Bible Hub is a great tool. They’ve also got Tyndale’s translation available. If you’re really wild, Erasmus’s 1522 Bible translation is over at archive.org.
