In mainstream theology, there is an idea called Post-Denominationalism that the Church banners Christians from all denominations. I'm sure many of you here already know about this idea (at least half of the fifteen of you

), so I don't think any more of a description is necessary.
Since I have been in the Oneness church, I have noticed a few things a fellowshipping. Some churches just will not do it. This could be because of different standards among churches, or because pastors are weary of their congregations being hurt by those whose mouths don't always stay closed on certain issues.
I know some Apostolics who will make excuses, have sympathy, or look around varying beliefs among the Baptists, Methodists, Nazarenes, etc., but who will always tend to ridicule or question the sincerity of other Apostolics because their standards or teachings do not align specifically with theirs. This makes absolutely zero sense to me. None.
To what measure do we fellowship with other churches?
Is it beneficial or not?
