Answer #1 (Stay UMC)
The good news is that the UMC is neither changing nor seeking to change the words of Scripture or the Lord’s Prayer, and the latest hymnal revision took place almost 40 years ago in 1989. An individual UMC Christian or local Church may have a unique opinion about matters, but no one person or church speaks for the entire denomination. Information about the United Methodist Church changing sacred texts is simply untrue. The United Methodist Church believes that scripture is the primary source and criterion for Christian doctrine, and we interpret individual texts in light of their place in the Bible as a whole. We also lean upon the legacy of church tradition, reason, experience.

In these disagreements we were able to remain united in spite of disagreement. In cases where words of a hymn may be clarified a change was made years ago so that people would feel included and part of the church rather than excluded. The last hymnal update occurred in 1989 and there are no plans for a new UMC hymnal.

Answer #2 (Pro-Disaffiliation)
Some of the words of traditional hymns have been changed to include politically correct pronouns and phrases. The hymn “Have Thine Own Way” no longer contains the phrase “whiter than snow” after “wash me just now”. Some UMC congregations, specifically First UMC Birmingham, use the language, Our Father/Mother Who Art in Heaven”, to begin the Lord’s Prayer.
