Since my Facebook post caused quite a bit of conversation regarding whether or not children belong in a Worship Service I thought I would move the conversation to this venue in order to clarify my question and my thoughts regarding this topic.
First, let me say that I do believe that this subject deserves much more in the way of dialogue than most Sr. Pastor's are willing to have. We have created a culture within our churches that segregates children from all else in order to create "Environments where guests and the un-churched will not be distracted." It is my personal opinion that this is a grave mistake. Putting the practical implications of this aside, (Children who do not know how to behave in a worship service or interact in a multi-generational venue.)we must understand the deeper issues.
In the end, we must go to Scripture to find the principles, and maybe even the commands set before us with regard to this discussion. Thus, my question regarding the sufficiency of Scripture.
It is important to understand that to get a balanced view we must also understand that the primary Discipler in the life of a child should ALWAYS be the parents. It is NOT nor has it ever been the respondsability of the Church to be the primary Biblical teacher of our children. In fact, Sunday School and Children's Church are quite new concepts in the life of the Church. It is also important to note that Sunday School was not "invented" for the purpose of teaching Christian kids, in Christian homes to attend. It was created for those children who did not have that kind of teaching/training in their homes. (The unsaved/un-churched.) It doesn't take one too long to see the results of Parents giving over the primary training of Scripture to the church.
All throughout Scripture we find examples of children being present with adults during times of Scripture teaching. In fact, they must have been present during the times that Jesus was teaching the Disciples. (Matt. 18:1-5) (For more examples of the commands in Scripture for Children to be brought to Corporate Worship just shoot me an e-mail and I'd be happy to send those to you.)
Finally, lest you think I am proposing the dissolution of all things Children's Ministry let me assure you I am not. There is, however, a real need for us to understand that in order to reclaim a generation (and further generations) we must get back to what God's true plan was. PARENTS MUST DISCIPLE THEIR CHILDREN. The Church provides SUPPORT.
That looks like this in a Christian church going home:
Parents: Primary spiritual teacher/trainer (in missions, evangelism, scriptural knowledge)
Church: Support system through clubs, SS. classes, etc.
Peers: Encouragement/Social (Youth ministry, Camps etc.)

In the life of an unsaved/un-churched child/teen it looks like this:
Peers- The first line of evangelism
Church- The connection to the Body of Christ and Scripture
Parents- Hopefully reached through the ministry of the church to the child/teen

So when I asked the question here is what I was getting at:

1. The sufficiency of Scripture
This issue, and all issues of Christian living, needs to be approached through the
lens of “Sola Scriptura.” God’s Word has given us all that we need, by way of its
commands, as well as its patterns, for all decisions related to faith and practice. So
our concern on this question of “do children belong in church?” or “should
families be called to worship together in church?” needs to be addressed with the
patterns1 and commands found in Scripture. “Sola Scriptura” points us to ask, “If
we only had the Bible to refer to in making a decision about this issue, what
would we conclude?”
2. The responsibility of parents to be the primary spiritual trainers of their children.
The responsibility for the discipleship of children is given to parents as the first
application of the Great Commandment in Deuteronomy 6:5ff and directly to
parents, specifically fathers, in Ephesians 6:4.
“Love the Lord your God with all your heart, with all your soul, and with all your
strength. These commands that I give to you today are to be upon your hearts.
Impress them on your children. Talk about them when you sit at home.” - Deut
6:5ff
“Fathers, do not exasperate your children, but bring them up in the training and
instruction of the Lord.” – Eph. 6:4
3. The vision of multi-generational faithfulness spreading the gospel to all nations.
The third foundation for this issue has to do with the mission of the church to
make disciples and to spread the gospel to all nations. Throughout the Scriptures,
from the first command to multiply throughout the earth, a vision and plan is
presented of generation after generation of God’s people bringing the message of
God’s truth and love to all people. The link between the discipleship of children
and the mission to bring the love of God to all nations is clearly seen in Genesis
18:18-19 where we discover that Abraham’s specific responsibility in seeing
God’s kingdom mission fulfilled was the spiritual training of his own children and
descendents.

In short: Parents, take back your role as the Spiritual Leader of your children. Give your children the opportunity to be involved in multi-generational worship. Know that they are far more capable of understanding "adult" teaching than what we give them credit for. Let them see you worship the God that you love. Let them see the ENTIRE church (the Body of Christ) in Worship. Help them feel accepted and a part of what we have gotten so good at excluding them from. Finally, forget the idea that a Sunday morning Worship Service is a venue for deep Biblical teaching. That should happen in our SS classes, Bible Studies or even in our own personal feeding times etc. (I've probably opened another can of worms with that one!)

We need to work hard in a decaying society to claim the next generation for Christ. I truly believe that if our families will start at home and then worship together with the Body of Christ we might just have a fighting chance.
