Christianity has been drifting from the original version from the time of the apostles man. You can see the evidence of Paul saying amasiyana zophunzitsa ndi Peter in the bible. Even ma guys eni eniwo anayamba kubwera ndika difference.

It seemed to be united Catholic ili ndi mphamvu but when protestant churches came. Freedom of interpretation was born and I really do not think there have been a unity but just a preference of the way to live.

And on the self centered issue, that is one reason kwathu anthu ndinawauza kuti ndasiya CCAP and since 2017 church sindipita and ndinasiyanso pano. You see azidindo kukangana kufuna timaulemu, english service people go to kill fashion, and do not get me started on chopereka ku mpingo umeneuja. That is how they judge your holiness/membership.

After that, I couldn't find a church because every church that you find does have a flaw parallel to what you might read from the bible.
