A Baptist pastor preached "we don't build on tradition; we don't build on liturgy, we build on scripture". That's fine but what if the Bible is a liturgical book? What if you can't separate the Bible from tradition, from liturgy. The elements of the Mass can be found in the Apocalypse.
Anything added to faith in Christ voids that faith for righteousness.
Accordingly, your position is sound. If one is building upon Scripture as though one is rationalistic rather than faithful, a good argument might be posed that one is committing the same error as those who build their faith upon liturgy or tradition, i.e. thinking that if one performs an act of crossing themselves, they have been faithful merely based upon the act, or if one studies and practices the books of tradition (I would like to say the Talmud independently of the Torah, although my knowledge here is limited), one might also assert that the object of faith is no longer God Himself, but rather a counterfeit, albeit a religious substitute.
Conversely, when we are built up by building precept upon precept, our faith and continuing faith or doctrine, is built by the Holy Spirit working within us.
The Word of God, is merely His communication revealed to man and recorded in written format. Our thinking that revelation from Him is consistent with His righteousness, thereby maintaining a situation where He may continue by grace to further develop our faith. It is only by His grace that we grow through Him at all.
In this fashion, we may build upon precept, upon precept, based upon His Word, but our faith only grows by the work of the Holy SPirit indwelling us. This is why it is so very important to remain and/or return into fellowship with Him by confession of sin and repentence, each and every time we study His Word. In this fashion, He is free in His Perfect Holiness to bestow His grace upon us by growing us in our understanding, thinking and walking, both in our thinking or soul and our spirit, leading to a cleansing of our heart.
Failure to return to Him by His protocol, and then reading the Bible, merely places us further is debt to Him as we actually begin to scar our thinking into a rationalistic legalistic perspective independent of faith. This might be classified as doin what is right in our own eyes rather than walking through faith in Him.
Such study leads to situations where many believers become frustrated with other believers, because rather than growing in the spirit through faith in Christ, they have degenerated by legalism into studying Scripture separate from faith in Him, but training their rationalistic thinking to be their counterfeit crutch, rather than living by His living Spirit.
Good point. The Gospels were meant to be read in church because that his how books were read in those days. The congregations were literally hearers of the Word. Even people who could read sounded out the words. St. Ambrose in the 4th Century was famous because he could scan words on a page without moving his lips.
