Those who esteem the Lords requirements for holiness and righteousness as indicators of truthful and loving Christian fellowship would agree that a lack of fruit indicates little presence of the aforementioned characteristics. Lest we forget to mention that one who affirms such a thing would do well to remember that the insanity personified in the Corinthian church was a poor example of such fruit. So does right fruit and wrong doctrine nullify one or the other?
But in the opening verses of the first Corinthian letter, they are addressed as the church of God at Corinth. Not only are these saints considered the church, they too are given admonition and instruction on correcting their behaviors. So at what point to we elevate our soapbox high enough to be able to separate one believers (or group of) errors from that of another? Do we have the authority or ability to rightly divide the doctrinal discrepancies that tend to splinter Christians into formed factions of militant stature? Just what compromises must be made in order to cultivate a Christian unity that bares a testimony of life changing, life giving, regeneration of the Holy Spirit?
