Following are a number of back-translations of Romans 5:15:

• Uma: “But the work of Adam and the work of Yesus are indeed different. The free gift [lit., dry gift] of God to us is bigger than the transgression of Adam. From the transgression of that one person, all mankind die. But indeed bigger is the goodness of God’s heart that he gave freely to mankind with the mediation of Yesus Kristus.” (Source: Uma Back Translation)
• Yakan: “But they are different because we (dual)/one cannot compare the sin done by Apu’ Adam and the love-gift of God. For because of the sin done by one person only, Apu’ Adam, the destiny of all men is to die. But much greater/important is the good done by one person also, Isa Almasi, for because-of what he did many people can receive the love-gift of God, that means his love and pity/mercy to them.” (Source: Yakan Back Translation)
• Western Bukidnon Manobo: “But the two of them are not the same, because the transgression of the one is not like the becoming righteous which God makes possible. Adam was just one person, but because of his transgression all mankind die. And in spite of that, much greater was that which was made possible by means of the kindness of God; for because of the kindness of one man also, who is Jesus Christ, God gave righteousness and He made many people righteous.” (Source: Western Bukidnon Manobo Back Translation)
• Kankanaey: “But admittedly the outcome of what they did was not the same, because what God gifted on account of Cristo is far different from what happened on account of Adan’s sin. Because due to the sin of that one, all people were condemned to die, but much-weightier is the outcome of God’s grace and what he gifted to all people because of the grace of the one who was Jesu Cristo.” (Source: Kankanaey Back Translation)
• Tenango Otomi: “Here is what happened because of Adam’s sinning and here is what happened because of the grace of God which was given us. Adam committed sin, and thus many people had brought on them that they die. But Jesus Christ is the one who brought us God’s grace and many people had brought on them that they will be saved. It is more powerful what Jesus did than what Adam did.” (Source: Tenango Otomi Back Translation)
• Central Mazahua: “What Adam gave us is not at all like what Jesus Christ gave us. Many people died because one person did sin, who is Adam. It was given to many people that God would look on them well, that they would live, because one person did good, who is Jesus Christ.”
• Teutila Cuicatec: “Adam’s sin was not the same as God’s mercy for us. Because of that one person all people owed sin but that’s not how it was with God’s mercy. He sent our Lord Jesus Christ and that one person in all love saved a great many people.” (Source for this and above: Waterhouse / Parrott in Notes on Translation October 1967, p. 1ff.)
