The very meaning of the word "church"(Eklesia) means those "called out of" sacrament. ceremony, tradition, and religious festival.. (John ch 10) and other places....
Even the word Sabbath is trumped by the Holy Spirit(paraclete)..
Jesus treated all seven days as the sabbath..
Example: Love the Lord your God, and treat your neighbor as yourself... 24/7..
On the Sabbath:
For he that eateth and drinketh unworthily, eateth and drinketh damnation to himself, not discerning the Lord's body.
For this cause many [are] weak and sickly among you, and many sleep. - I Cor 11:28-30
I sometimes wonder if you even know what day of the week it is.
Man! You gotta flesh some o' this stuff out.
(Hostile way to put it: If you want to draw fire, you have to stay out of cover long enough for us to think we might have a shot.)
(Friendly way to put it: Boy? Whatchoo talkin' 'bout?)
My personal theory about ecclesia is that, yeah, as you say, it parses out to "Called out". The root verb is Kaleo. I don't know what other verbs the LXX translators had available, but they must have been aware of the similarity between kaleo and qahal.
And, en passant, I have always taken pleasure in the name some of the brethren use for themselves, "The Assembly of God", since it is so close to Qahal Adonai (Where Adonai is a reverential periphrasis for, well, you know.)
But I was left adrift by the Sabbath and the "Summary of the Law" remarks. I'd appreciate it if you'd say a little more there.
Go ahead, draw my fire. I'm such a crappy marksman I'll probably miss anyway.
While I wait, I'll work on trying to firm up my thinking on the dialectic of inclusion and solitude, of "called out" and "called together", and see if I can say something coherent.
