Hardly, I said that the Bible Only contains the inspired words of God.
As in, "only the Bible contains the inspired words of God?" If so, then I don't see how you could square it with this:
Those words affirm the authority of the church and of true guidance from the Holy Spirit.
But if the Holy Spirit "provides guidance," then that's God providing information from a Source other than the Bible.
So ... what is your definition of "Bible Only?" It seems not to match the way the authors use it.
The Bible Only means that no other source is the repository of the Word of God.
That the Bible affirms the authority of a faithful Church or of times when true promptings of the Holy Spirit are made evident does not diminish the authority of the Bible.
How do you see me using it differently?
