I'm not orthodox, but born again (holding to most of reformed doctrine). I can't speak for anyone but myself and my brethren also professing a personal relationship with God, but we find fellowship with God in reading scripture (not exclusively but in learning scriptures meaning and application to life.) I've read through the Bible dozens of times, and every time the Lord teaches me new things about Himself, about myself, and about life.
It's wonderful to be taught by the Lord in scripture and in life. When the Lord illuminates a verse, it's His Spirit saying "see this, it's about Jesus Christ," or "it's about you and your sin", or "its about that situation in school, or at work."
When you're walking on your way and the Lord shows you someone and gives you verses in remembrance, He's saying this person is like this and needs this.
The scripture is light for our path, not just a rule book or instruction manual. How do you live if it isn't by every word that proceeds from the mouth of God? How are you lead by His Spirit if you don't know His word and how He applies it in you and through you to the situations of life?
You don't have to know the scriptures to receive His Spirit, but His Spirit works His will according to His word. How can you pray according to His will without knowing what He's said?
Is Christianity just "Judaism 102", studying scriptures to build a philosophy, or is it knowing God through His Spirit received by faith in His Son, and walking with Him in obedience?
I apologize if you receive this as criticism. I'm unfamiliar with any orthodoxy except Roman Catholicism (which I abandoned at the age of 13). But how do you perceive your faith, as religion, or as relationship with our Lord and creator?
