Peter J. Leithart on songs of the church militant :
Christian worship is inherently political. As Bernd Wannenwetsch points out, this isnt because worship is a tool for ginning up enthusiasm for a candidate or for stirring the fires of patriotism. On the contrary, It is just because Christian worship is not a means to an end that it is political. Worship is political because it opens out into the kingdom of God, and because in her worship the Church anticipates the city of God with its eternal liturgical assembly.
