Where it appears, the title of "worship leader" should be critiqued, for it suggests a model of worship in which Christ has been displaced from his rightful place. In the Middle Ages it was the priest, now it is worship leader. Christ' displacement is accentuated by the focus, either implicitly or explicitly, on the leader's personality, charisma and gifts. In this regard, it is noticeable how the leader's causal greeting has replaced the traditional call to worship in many services. It is almost as though the worship leader is the host, welcoming people as he/she woudl to his/her home. Also interesting to observe is the role of the "worship team", usually consisting of a music group, whose task it is to open worship with a "worship time". This consists of a bracket of worship choruses, interspersed with the leader's exhortations, humorous asides and extempore prayers. A lot of effort goes into creating the right atmosphere. Music has come to assume a priestly role in much worship, insofar as it is regarded almost as the primary vehicle by which people enter the presence of God.
