I have been in full-time Ministry for 25 years and I have served in multiple denominations. I have nothing against the vast majority of denominations. However, the surge that we have seen in recent years of the anti-denominational mindset, the massive decrease of denominational membership, the mass closings that are going on of denominational congregations, and the huge rise in non-denominational congregations is actually a work of Christ's that actually started close to twenty years ago now, a move by Jesus to bring the church, the one church, back to what it originally was and what He founded it to be before man got his hands on it and brought such destruction to it. Many denominational groups have attempted for years to fight against this, much to their detriment and without success, but they desire to hold on to their petty differences instead of embracing the Truth of the fact that Jesus established One Christian Church.
Several denominations in an attempt to survive in a religious atmosphere that is now becoming intolerant of denominations has attempted to do so by hiding who they truly are, through what one would call rebranding. I am not trying to pick on any particular denomination but the one that is most prominent for doing this is the Baptist denomination. If you will note in the last 5 years an untold number of Baptist Churches, most of which that are not known as First Baptist Church of... , have removed the word Baptist from their name and given themselves very generic names as to appear to be, at least on the surface, non denominational. Your average church member is not aware that this is the reason for this action only ministers and pastors who are actually involved in the workings of denominations at an associational level are fully aware of what is going on. This is being done for obvious reasons, they want to survive, they want to draw new members, and they cannot do that any longer by branding themselves as a denomination.
Jesus is involved in a work through The Holy Spirit to bring the Church back to what it was originally meant to be. Before Christ returns the Christian church will come full circle, back to what it was like in the beginning.
