I looked at the same article, if the worship indicates that it has contempory, post-modern, blended, jazz or anything else than traditional, I run as far away as I can.
After we moved and we looked for a new church, I checked the websites of LC-MS churches, I found that there are some LC-MS churches that are ashamed of the Historic Liturgy and because they are trying to be Church Growth and Wannabe Baptist or Pentecostals. These type LC-MS churches all have praise bands, stages, and big screen TV to follow the bouncing ball for their songs. The LC-MS church that we attend has two traditional services each Sunday and communion each service.
