For when one says, "I am of Paul," and another, "I am of Apollos," are ye not carnal? 1Co 3:4 (NKJV in this post)
Now if anyone builds on this foundation with gold, silver, precious stones, wood, hay, straw, each one's work will become manifest; for the Day will declare it, because it will be revealed by fire; and the fire will test each one's work, of what sort it is. 1 Co 3:13
IMO, no matter which of the many, many Christian sects any of us happen to belong to it seems to me that the Lord has a plan. I think that even though many have built, many will burn.
Many handle these scriptures like they are the arbiters of how these thing apply, as Wierwille and my former splinter group leader has done. People still say, "I am of Wierwille" and "I am of Barnard."
Since they built their groups upon fleshy and carnal confessions such as these isn't almost a forgone conclusion considering the straightforward way that Paul warns Apollos and the church of Corinth about these carnal loyalties that they will inevitably reap the reward for their sects.....FIRE!

Heck, as a matter of history, even Luther had people who after his passing talked about he was the Man of God for his Day and Time.
And looking back it seems that they fell into error and left aside reason in their carnal loyalties for even Luther.
