After reading the book there is no certainly no doubt that von Balthasar had a brazen distaste for anything medieval. At least that is what is conveyed in this particular work. In one of his rants, which laments the middle ages, he balks heavily at the church buildings of the time as not being conducive to a communal celebration. Many today make the mistake of separating today's liturgical disaster with the theology and philosophy that sustains and gives life to it. Balthasar's insistence on the absorption of the Church into the world, also forces him to lose his focus on man's ultimate end, which is God. We can see that he loses man as merely part of a worldly communal celebration, rather than part of a heavenly and saintly family looking vertical to the worship of God. We have seen this type of thinking with all of the "New Theologians." Community, or horizontal worship trumps the vertical worship of God. Although little is said in the book on liturgy, it is plain that his corrupt line of theological thinking concerning the Church and the world, had also corrupted how he viewed man's relation to the worship of God.
"The church buildings of that time (such a heavy burden for our acts of worship today, since it is impossible or very difficult to realize the liturgy in them as a community celebration) at best allowed only the lay elite into the most sacred precincts, while the people had to remain in the back."
