Do you mean Sola Scriptura? Which states the Bible as the sole infallible source of authority for Christian faith and practice?
No, he meant Solo Scriptura.
Solo Scriptura =/= Sola Scriptura.
Sola Scriptura is an historic norm among most Protestant traditions.
Solo Scriptura is very different.
Example: As a Lutheran I subscribe to Sola Scriptura, though in the language of the Lutheran tradition we tend to speak of Scripture as the Norma Normans, Latin for "Unruled Rule" or "Rule that Rules"; Scripture rules over everything in Christian doctrine and practice, and there is no higher rule than Scripture. But we also speak of the Norma Normata, Latin for "Ruled Rule", that is, the norms, or the things we regard as authoritative and important, but which are ruled over by Scripture. The Nicene Creed is authoritative, it is a norm, a rule, a standard for Christianity--to reject the Creed is to reject the Christian faith; but this isn't because the Nicene Creed is the chief authority, rather it's because Scripture is the chief authority and rules over the Nicene Creed.
That is an example of Sol
a Scriptura in practice.
Sol
o Scriptura says, "The Nicene Creed isn't the Bible, so I reject it."
Other examples, would be something like this: The Bible does not explicitly command that we have pews in churches, therefore pews are wrong. That would be Sol
o Scriptura. Sola Scriptura would say whether we have pews or not doesn't matter, Scripture is entirely silent on the issue, and so whether we have pews or seating in our worship spaces or don't really just doesn't matter. It's perfectly fine if a church has pews, and it's perfectly fine if a church doesn't have pews.
"The Bible doesn't mention the word Trinity, so I don't believe in the Trinity" would be yet another example of Sol
o Scriptura.
Sola Scriptura = traditions are fine, and even good and useful and authoritative when they are in agreement with Scripture, when they are beneficial for the Church, when they aid in Christian worship and Christian practice, when they promote the Gospel, when they promote godly living, etc.
Solo Scriptura = if it's not right there in the Bible explicitly, it's bad and wrong.
