In 1978, the Synod in Convention abruptly withdrew from the joint hymnal project with the LCA and ALC. Thus the Lutheran Book of Worship was published in 1978 without the participation of the very denomination that had initiated its production, angering leaders in the other church bodies. Congregations of the Missouri Synod objected to the use of the 1977 revision of the Book of Common Prayer in the hymnal as well as the hymnal's use of the Revised Standard Version as well as many other concerns. The hymnal committee of the LCMS attempted to address these concerns as well as remove much of the objectionable content and published a recension of the objected hymnal in 1982, the Lutheran Worship. However a high level of mistrust in the Missouri Synod between her congregations and denominational leadership meant that the new hymnal was poorly received. A study commissioned by the Missouri Synod in 1999 found that 36% of congregations used the older hymnal, with the rest using some combination of both and only a few exclusively using the "newer" hymnal published seventeen years prior to the study. Thus the Missouri Synod entered the 21st century lacking unity even in its own hymnal.
