And thus, the first time I think I've disagreed with you about anything.
Opening post talks about youths being separated from parents, and how one group is talking about it being wrong; verses from Nehemiah seem to support that family members (at least those that are able to hear with understanding) should be together. Not sure I'm understanding why you think the verses are "coincidental."
"Arbitrary" - a course of action or a decision that is not based on reason or judgment but on personal will or discretion without regard to rules or standards.
Thanks to the military, I've been a member of about a half dozen different churches. One church has "children's church" for 4th grade and under; another says 3rd grade and under. As I mentioned in a previous post in this thread, my current church sends the 6th graders and under out to one location, and teens to another.
I don't know what the average Southern Baptist, or Reformed Baptist, or Landmark Baptist, or Freewill Baptist, or GARBC, or other churches practice or determine as their "standard." Thus, my use of the term "arbitrary."
At my church we send elementary age to children's church and 6th & stay in the sanctuary during the morning service. Sunday and Wed nights they go to their classes. There are plenty of ways to do things as a family at church. If the children are in the sanctuary then they are getting little to nothing from the word. That is just not helpful. We should be teaching and encouraging family worship at home as well.
Every time we turn around these days there is someone else who thinks they "now" have the inside scoop on how church should be done and everyone else to this point has been wrong and unbiblical. Such attitudes always carry no credibility with me. Personally I am suspicious of them that they have another agenda they are not willing to reveal up front. Largely because of what i have already said and the arguments are spurious at best.
