There is no question that simply being in the Bible and citing scripture is not foolproof against the deceptive wiles of the devil. Numerous sects and heresies which is a term meaning deviations from the truth have been spun out of just that sort of practice. So the answer can’t simply be to just get back to the Bible, unless that’s qualified as to specifically what is meant.
Scripture itself points to the church as the pillar and foundation of the truth, so that any biblical interpretation apart from consideration of what the Spirit has been saying to the churches and the church at large is automatically suspect. Individuals have divided over mistakenly supposing the Spirit had given them insight which either contradicted others, or gave a needed insight. The richness of scripture and Christian orthodoxy, the Christian tradition is apparent when one begins to look and dig deeper into scripture itself, and the patristic (church fathers) sources.
We can’t rightly or even possibly consider the Bible apart from tradition. Our translations of scripture are dependent on interpretation to some extent, an interpretation that does do justice to the Book at large, but does provide answers where interpretations might vary. The church in the early centuries is an example of this: reacting to various heresies, like the idea that Jesus had a beginning and is a created being, not God. The church instead came up with the truth from scripture that Jesus is both completely God and completely human, two natures separate, not intermixed, yet indissoluble (permanent) in the one person. And the teaching of the Trinity, that God is one God, so that we can speak of God that way as one person, yet three equal Persons in that one God: the Father, the Son, and the Holy Spirit. When the Protestant Reformation occurred, these past formulations were not under consideration for revision. Martin Luther didn’t want to leave the church, but reform it. But when what is called the Radical Reformation occurred, it was essentially a restorationist movement, with the goal of becoming strictly a church in accordance with scripture, specifically the New Testament. The Anabaptists were one such group, and Menno Simons early on was misunderstood to be a heretic when it came to those early formulations, and soon realized that one can’t leave tradition behind. He made it clear that the Anabaptists accepted the teaching of the Trinity, and of Christ’s two natures as formulated by the church in those early councils.
It does seem to me like we live in a day in which people need to get back to scripture. Certainly not to read it as a flat book, as if it is all equally applicable today. To see it as the unfolding story it is, fulfilled in Christ, and to be completed when he returns. But scripture itself seems to have fallen on either deaf or complacent ears to a significant degree among believers. The diminishing of biblical knowledge among church goers seems to have been occurring incrementally for decades now. And today, either people don’t know, or little care, or they easily misread scripture in defense of an agenda which is actually based on something other than God’s word and will. Not to say that any of us are immune to any of this; we most certainly are not.
Maybe we lack interest in scripture in part because our expectations are elsewhere. We love this or that, and feed on such, with just a bit of time left to maybe get to a reading from the Bible. We fail to dig and ponder, read and wonder, study and think, and pray. We connect elsewhere, finding scripture irrelevant.
Instead in this day maybe like in none other, we need to regularly plug in and find our way through God’s word, which is called a lamp for our feet, and a light for our path. We need to look at current thinking in light of scripture and the gospel. Including of course our own thinking and practice, which so easily is and can be misguided.
And we need to find our way to a church which believes and practices the word, with of course the realization that the gospel, the good news of God in Jesus is the point of it all. And all the richness and vitality that comes out of that.
May God help us to live out what we are as God’s people together by the Spirit through the word in and through Jesus.
