Which church is the right one? Aren't there enough Christian assemblies out there? Some thoughts about this:
1) Who belongs to God's Church?
All who believe in Jesus Christ and know Him as their personal saviour belong to God's church. The Bible also refers to all believers as the body of Christ, and Christ as the head of the body. This is not about being an official member to any church or association but only to believe in Christ - regardless of the fact that you belong to or meet with any Christian group.
2) Christians gladly assemble!
There is no example in the Bible of any Christian remaining alone in his/her faith. The Bible always mentions fellowship with other Christians. As all believers are children of God, they should meet as a family in faith to have communion - with each other and with God (cf. 1.John 1:3).
3) Why do Christians meet?
The first Christians met regularly for the following events: listen to and share biblical messages, partake in communion with each other, celebrate the Lords Supper for remembrance and testify about the Lord's death, collective prayer meetings (see Acts 2:42; 1.Corinthians 11:23-26; Matthew 18:19).
4) Where do Christians assemble?
Today it is practically impossible for all believers to meet in one place. The Bible also refers to assemblies at a specific local place (e.g. 1.Corinthians 1:2). The basic principles of God's worldwide church shall be shown and practised locally (in as much places as possible) in order that the assembly becomes visible by the meetings of Christians. The physical room or the building is irrelevant - the first Christians held their local meetings in their own homes.
5) How do we assemble?
When Jesus Christ was on earth, He told his disciples: "Where two or three are gathered together in my name, there I am in the midst of them." (Matthew 18:20) When meeting as assembly, we are honoured to do it "in His name" - i.e. all authority must be given to Jesus. Practically speaking: The Bible is the one and only authority on this subject, not well-intentioned human ideas or traditions. Jesus promised to be in the midst of such meetings! (Knowing Him in the midst should be another reason to assemble, of course.)
6) ... and what about other churches or gatherings?
We feel drawn to all children of God, and thus we do not have any registered membership, and we do not belong to any organization or association or have any special name for ourselves. Our aim is not to segregate from other Christians since the New Testament only mentions one name (Acts 11:26). We neither agree with everything that happens in Christianity, nor do we want to equalize deviations - but generally, the Bible only speaks of one church/assembly.
