Concerning the long, green season of Sundays after Trinity, the Roman Catholic priest Pius Parsch (1884-1954) observed:
What a glorious treasure of catechesis and confession of Jesus and the Christian life the Church Year is! And how impoverished are the megachurches - including those nominally in the Missouri Synod - who have ditched the illustrious riches of the liturgy and its glorious teaching of the Christian faith and life in favor of the threadbare rags of worldly entertainment.
The traditional liturgy reminds us that we are the Church Militant through which the Lord trains our hands for war and our fingers for battle, preparing us to make war on the enemy - while entertainment worship just makes for soft, flabby, and infantilized Christians (including neutered and feminized pastors) who are clueless about what is truly happening behind the veil: the great spiritual warfare that rages around us, which will only increase until the return of our Lord.
