No group. After I was redeemed, I picked a little bit of information here and a little bit there. Right now the Internet is my Church and I really do not care what 'titles' people place over themselves.
Catholic, Protestant, Evangelical, Pentecostal, etc., means absolutely nothing to me. Those are man-made titles and I disregard all of them. I look for "Jesus Christ and what He did at the Cross of Calvary" exclusively for salvation, justification, sanctification, and for everything else needed.
I find it amazing that so many have this need to associate by denominational belief instead of taking into regard what people say they believe as in the Gospel of Jesus Christ, which is the true denomination and doctrine.
I have said that I believe that there is a reason for the divisions within the body of Christ such as differing denominations and the only reason I can think of that someone would not accept someone telling them that they follow the one true denomination and doctrine of the Gospel of Jesus Christ is because they feel their denomination and doctrine must be closer to the truth than the Gospel itself. This need to attack or embrace leaving nothing inbetween to be regarded.
Within the continuum of Gods will all believers reside, some are simply closer to the center of it than others.
If my spiritual conviction is not to subscribe to a doctrine that I feel is not consistent with the Gospel of Jesus Christ, why then would that be so offensive to another believer? The sad fact is that I feel that most denominational doctrines fall short of the truth in the Gospel of Jesus Christ and that I've had more spiritual success with prayer and seeking via the Holy Spirit than I've ever had with regard to associating myself and subscribing to something I don't agree with.
We should all be at peace with one another understanding that there is a reason for this division, that it will inevitably work through tribulation which brings patience and perseverance in all things and people who love the Lord.
Live ones own conviction, do not judge, discern the spirits of individuals and trust the Lord will lead you in the right direction. Never toss the baby out with the bathwater and know that truth is scattered in many places and those who seek the Lord with a sincere burning desire to know His truth...will indeed find it.
