There is truly only one universal church. This universal church is, in spirit and in truth, The True Church or The Body of Christ Jesus. It is made up of many and varied members. These members are those found throughout the world in various local church fellowships, missions, organizations and denominations, etc.; a scattering of salt throughout the world. They may not be fully aware of their place strategically within the Body of Christ Jesus, but as genuine believers in Christ Jesus they should be aware that they are indeed a part of the Body of Christ Jesus. It is in so many ways a church without boundaries, for it is a church of the Spirit. For me, this is the bottom line.
Not everyone who says they are a believer is a believer in spirit and in truth. This is also true of the church, not everyone or every church, mission, organization, etc. is actually a genuine part of the Body of Christ Jesus just because they claimed to be. Having said all of this I am aware of a very real danger. This danger is that one would leap into trying to discern that which is the true church and that which isn’t? I am saying that this is a danger in that we are not exactly called to this. We could say as scripture says, that we shall know them by their fruit and this would also be true for the church or churches as it is for individuals or even nations, etc.
