I get what you're saying here, but has nothing to do with "assembling together".
!0,000 church sins leaves no excuse to commit one more.
I know what you mean.
It’s actually “the assembling of ourselves together”. The writer did not use the word for “meeting”. He used a different word, a word
only used one more time in scripture when it references our assembling to the Lord.
“Now, brethren, concerning the coming of our Lord Jesus Christ and our gathering together to Him…”
I certainly support fellowship among the saints and getting together often. The scriptures are clear about this.
The passage is also set against “a Day”. Capital D. “When you see the Day approaching”. This is not Sunday. This is the return of the Lord. We should be more earnest to walk in the assembling of ourselves together as the Day approaches. The reason is obvious: there are dark day leading up to the Lord’s return. The exhortation and encouragement from the Lord will come to the Body through the body. If we are not fit together and if we cannot discern the Lord in others we will not receive what is given to the Body.
Now, this happens locally, in small groups, and this occurs in cities: e.g. in the city of Corinth the saints would occasionally gather all at once but they would also gather in smaller groups in the households of Chloe or Aristobulus or Narcissus or Stephanas, etc.
Paul admonished the saints in Corinth for sectarianism, preferring to be divided according to men of the Lord who were sent to them…
“Now I plead with you, brethren, by the name of our Lord Jesus Christ, that you all speak the same thing, and that there be no divisions among you, but that you be perfectly joined together in the same mind and in the same judgment.”
“For it has been declared to me concerning you, my brethren, by those of Chloe’s household, that there are contentions among you. Now I say this, that each of you says, “I am of Paul,” or “I am of Apollos,” or “I am of Cephas,” or “I am of Christ.” Is Christ divided?”
Do you think the saints today declare, with a clear conscience, “I am Baptist” or “I am Lutheran” or “I am Calvinist” or “I am Evangelist” or “I am of Christ”? I do. I think they think nothing of it. They think it’s normal and even appropriate.
