So you don't believe in the Bible Alone either? Good.
As I said there is no difference. The Word is Jesus, Jesus is the Word. Belief in One is belief in the Other.
Depends.
Sola Scriptura means, to me, that the Bible is completely sufficient to establish me in a relationship with God and see me to maturity in God and to eternity with God.
That does NOT mean, Holy Spirit is flushed and that Scripture is ever without Holy Spirit's involvment.
Holy Spirit, however, tends to be a still small voice easiliy overridden in many lives by magestericals local and far; full bladders; TV noise . . . and a million other priorities.
Nevertheless, when the focus is God's Word and seeking God's face for God's priorities for the individual and the day--then Holy Spirit is quite responsive in assisting in leading into all Truth AS CHRIST SET UP AND DECLARED HE WOULD.
