Psalmodic Response is responding to the gist/essence/spirit of a half-verse, by applying it in the same 'spirit' in the next half-verse. Thus, Psalm 1:1: First half-verse: 'Blessed is the man that walketh not in the counsel of the ungodly,'
Now, Scriptures shows us how to show that we understand the first half-verse, by showing us how to respond by applying the spirit of the first half-verse into a different situation. thus 'nor standeth in the way of sinners, nor sitteth in the seat of the scornful.'
This glorifies the word, makes it 'heavier,' more 'kabod,' in Hebrew--heavy. Unity in complexity.
I propose that our whole life is to be such a response to the whole of Scripture.
And if history is a chiasm, then we see an even more artistic response. Thus ERH says that it was tribes, empires, Israel, Greece, the Jesus--the Pivot, the Reverser of the Trend--and, chiastically, the Church is the New Israel, glorifying with more, and more unity, ridding of exclusiveness; Nation-States were the New Empire, but ridding of slavery; and we are in a Neo-Tribal time now. [Greece must be a companion, not an orderer]>
I pray that I have articulated this wisely.
Love in King Jesus,
