When it comes to church practice, we do many things that cannot be found in scripture. This can be said, to one degree or another, of almost any local church (at least in the USA).
When we do things not found in the bible, they are almost always done with good intentions. They are usually based on pragmatics (and not on the scriptural model). If the question ever arises as to why we do these types of things, the answer is almost always that we have freedom to do so.
I'm not sure anymore if that is a good enough answer.
I think we can all agree that when we come together as a church, if we are doing things that the early church did, we can assume that these are acceptable (as long as the apostles did not tell them to stop doing these things). Why can we assume this? We can make this safe assumption because the apostles were there with them. For example, Paul knew well the church in Corinth. He planted it. We knew their problems and told them what needed changing. The things he did not tell them to change were, then, acceptable. Therefore, they are still acceptable today.
What about the things we do today that cannot be found in scripture? Here are some examples of things that your church may take part in: Sunday School, Children's Church, weekly offerings, paying pastoral salaries, meeting in special buildings, "worship service" ceremonies, sitting in pews, bulletins, choirs, etc. These things are all common but none can be found in the New Testament church.
I know many people who would look at that list and say that we have freedom to engage in all those activities because they follow scriptural principles. They may also say that the bible nowhere tells us not to do those things, so we can go ahead and do them.
Here is my main concern: When we participate in activities that cannot be found in the bible, we do not know if they are acceptable to God.
We may convince ourselves that they are acceptable. We may even feel good doing them. We may want to continue doing them. However, this still does not take away the fact that we simply do not know whether or not these activities are in God's plan for His church.
Let me bring up another example. In most churches there is one pastor who preaches almost all of the sermons. The sermon is a largely scripted message based on hours of study during the week. The pastor preaches while the congregation/audience sits passively listening. There is no back-and-forth communication.
The sermon is unquestioned in almost all evangelical churches. It is seen by many as the high point of the service. Some people even believe this is the time when God speaks directly to them through the preacher.
Here is the problem: when we look at the early church, we simply do not see pastors preaching scripted sermons week after week. In fact, we see teaching but not preaching when the early church gathered. Also, the early meetings were participatory as opposed to passive.
The sermon as we know it was not part of early church gatherings.
So, should sermons as we know them be a part of our church gatherings? The answer is that we just do not know.
Is not knowing good enough for us? In unimportant areas of life I suppose it is. For example, I don't know if my shoes always match my pants. This doesn't matter because it is of little importance.
However, the church gathering is of utmost importance. We see many exhortations in scripture as to how the church is to function. We are told that we should gather together to edify one another. We are instructed in many things to do and not do. We are given the example of the early church to show us practices that are acceptable.
I hope your conclusion on this issue is that not knowing is not acceptable. The flip side to that is that knowing is acceptable. When we engage in activities that the early church took part in and were approved, we can know that they are approved for us as well.
I say all this as encouragement to follow the biblical model when it comes to the church. I've heard many. many people say that we don't have to follow the model we see of the early church. They say that what we see is descriptive and not prescriptive. My response is that they are doing a lot of things that they may think are good, but really have no way of knowing if they are.
When we follow the model set before us, we know we are acceptable to God. And it is His church.
