Following are a number of back-translations of Titus 1:15:

• Uma: “For people whose hearts are pure, there is nothing that is taboo/forbidden. But people whose hearts are evil and who do not believe, nothing is holy, for their thoughts are crooked to-start-with, and their evil behavior has become habitual [lit., has-become-flesh], until they no longer feel/are-aware that they are wrong.” (Source: Uma Back Translation)
• Yakan: “If a person has a clean/holy liver even whatever, it is clean/holy to him. But to a person whose liver is not clean/holy and he does not yet trust in Isa Almasi, there is nothing clean/holy to him because there is evil/bad in his liver and his thoughts and he cannot distinguish good and bad.” (Source: Yakan Back Translation)
• Western Bukidnon Manobo: “If there is a person whom God has cleansed, nothing can make him filthy. But if there is a person whom God has not cleansed, there is no other way for him to be cleansed. For he will not believe and his mind and breath are wicked.” (Source: Western Bukidnon Manobo Back Translation)
• Kankanaey: “As for the person whose mind is clean, his considering of everything is also clean, but as for the one whose mind is filthy who doesn’t believe, everything is filthy to him, because his mind has already become-filthy and he is not able-to-distinguish good and evil.” (Source: Kankanaey Back Translation)
• Tagbanwa: “The person whose sin has been erased by God and whose nature/ways have been made new, there’s nothing he avoids/taboos now like food, for he’s aware that everything is good. But to the person who is evil who doesn’t believe in God, it’s like there is nothing he regards as good, because it’s like everything has been contaminated by the evil of his mind/inner-being which no longer can recognize good or not.” (Source: Tagbanwa Back Translation)
• Tenango Otomi: “The person who has a good heart, just by touching something it cannot be said that therefore his heart has been spoiled. But concerning those who have evil hearts, and are not believers, in nothing will they find what is good. Because now their thoughts are evil and they do not feel sad when they do evil.” (Source: Tenango Otomi Back Translation)
