I just learned that Robert Webber, author of many books on worship, passed away. I met Dr. Webber a few years ago at a worship conference in Kansas City. His insight into the structure of worship was astounding.
Most what Dr. Webber wrote was a call to retain our heritage and tradition while also being able to experiment and advance. He did not want to drag everyone back into a liturgical worship style, but neither did he want people to lose their connection to the past. He focused more on developing a philosophy/theology of worship that informed everything a church did. (His 8 volume set on worship is astounding).
It is always sad to see a great mind, theologian, and God-lover pass away.
