Just sharing my own views as a response here, in recent years, I’ve come to more deeply appreciate what I see as the activity of the Spirit.
I see the Spirit as God’s agency of continued work and revelation today in regard to both old and new issues that we face. That is in direct contrast to “the Letter” in which it is deemed that something has been entirely nailed down by written scriptures already … the Lord has already spoken, and the matter is settled for all time. Protestants keen on being rooted in the Bible really, really insist on this because they have a - perhaps understandable - suspicion, even hostility toward anything that smacks of subjectivity or manipulation according to the vagaries of culture or prevalent sensibilities of the times. We want it nailed down, because any and everything not “nailed down” will get stolen and misused, or so we tell ourselves. And we have no shortage of examples to knowingly point at to drive home our point.
And yet, one can’t read very far into the New Testament without seeing that this really isn’t the way the Spirit did things in the early church. Yes - there are those passage wherein somebody is “searching scriptures” to see if something holds up - and they are commended for it. But there are also the many stories of the apostles pretty badly upsetting the “Let’s attend to scriptures” folks by deciding that the Spirit was leading them in new directions, which they -with no little controversy, decided they need to attend to, even if it meant no longer preaching and insisting on “the Letter” of scriptures as understood up to that point. Jesus did this plenty - and his disciples and the church fathers after him followed his example. Nowhere in scriptures are we warned against following these early examples - we are not told that they had special - but now expired dispensation to do this. We’re not told that we have to lapse back into some “more clarified version”, going back to following every Letter as a legalistic matter again. Those who want to go that direction are just making a new law “the Letter 2.0”, if you will, and going right back to being Pharisees with that again. But Paul will have none of this when you read Galatians, and he’s quite emphatically perturbed about it too.
So while all the “dangers of subjectivity” are quite real and in need of community vigilance, we nonetheless cannot escape the need - I would say even the imperative to be letting the Spirit lead us in fresh directions in how we understand and apply scriptures to our situations today. We really do like and prefer the “old wineskins” in so many ways - and Jesus anticipates as much - the “old wine” is just so much more comfortable and preferred by us - everything nailed down, it’s all about the Letter, and we don’t have to worry or think about anything, except … we discover life doesn’t work that way. But trying to put the new wine into the old skins doesn’t work either. I think the current and fresh leading of the Spirit is the “new wineskin” and new wine we’re called to take up.
