“And most of the Independent Fundamental churches do not follow Scofield.”
Doesn’t matter. He espoused sola scriptura and millions of sola scripturists use his Bible.
“As for Ruckman, the Bible says a person can be divorced for adultery, that is the only reason, but that a divorced person cannot be a pastor (2 Timothy).”
Well, he’s a pastor. And there are thousands of pastors like him who are divorced and yet still espouse sola scriptura. So, if claim that sola scripturists (especially pastors) don’t believe in divorce or divorce and remarriage, you’re clearly wrong. Many do. It happens all the time.
“Needless to say, there are many divorced pastors serving in churches today — in evangelical, Bible believing churches.”

Yes, you can make those points and they are correct. But in each case they have added something to Sola Scriptura to justify what they are doing.
Denominations are formed because people could not handle exactly what the Bible teaches, so tried to find a way to get around what it plainly says.
So you can claim they are Sola Scriptura and they will call themselves the same, but their books and writings always add to the scripture.
And that fate is plainly spelled out, Revelation 22:18-19.
