Further to my ‘Denomination Domination’ post I would like to speculate that we can be church amongst

Bewitched movies churches. I.e. just because you want to change your pattern of fellowship with other believers, you don’t have to exclude those in your current church (i.e. the church that you ‘attend’).

However, what does seem to be necessary is a re-prioritisation of how much time you are going to spend with who, but this is a long way off from dumping anyone entirely. Our mission of discipleship (internal church activity) should still be a priority in the situation we find ourselves – I tend to recall the passage around:
1 Corinthians 7:20
Each one should remain in the situation which he was in when God called him.

and imagine that this could apply to continuing to participate with the church we are in, whilst we allow ourselves fellowship with those from outside ‘our’ ‘church’.

Naturally there is a danger, if we practice this slightly subversive form of church, that existing church leaders might have a problem with us… but one would hope not! I imagine it would only be a problem if they were particularly territorial or possessive!
