Following are a number of back-translations of Romans 14:5:

• Uma: “There are also people who say certain days are more appropriate for us to-worship-on. Yet some say that all days are just the same. The main thing is: every one of us must really believe in his heart that God approves of what he does.” (Source: Uma Back Translation)
• Yakan: “There are people they regard/consider that one day is greater than the other days. There are also people they regard/consider the days as alike. You (pl.) ought to each one be sure as to what is your thinking.” (Source: Yakan Back Translation)
• Western Bukidnon Manobo: “In the same way also, one person considers that there are days which are precious to God, and another also considers that God does not consider any day more precious than another. It’s necessary that each one is convinced that what he thinks and does is the right thing to do.” (Source: Western Bukidnon Manobo Back Translation)
• Kankanaey: “There are also those who count one day as more-valuable than the other days, while others say there is no day which is to be differentiated as more-valuable. Concerning this, the mind of each one must not doubt that what he is doing is right.” (Source: Kankanaey Back Translation)
• Tenango Otomi: “There are some believers who say that there is one day which is more holy that other days. And also there are others who say that all the days are equal. Therefore each of the believers, concerning the word which they understand to be good, that is the word they should do.” (Source: Tenango Otomi Back Translation)
