All traditions were new once

As someone who does a lot of thinking, who loves coming up with ideas, wondering how things could be different - theologically progressive, ecclesiologically an innovator - that sort of person, I find myself sometimes at odds with traditionalists, who might not get or buy into all the change or new ideas.  However, it occurred tome recently that all traditions were new once. A tradition is simply something that is passed on, and someone started it sometime, somewhere. Like at school, when someone whispers something to the person next to them and says, 'pass it on'.  Rarely was it indisputable fact, unless you went to a really clever and studious school...
In the same way, traditions are always started off by someone who has an idea. At the time, it may be revolutionary. Imagine the person who came up with the wheel, they probably laughed at her/him. They probably got rejected by the Stone Age version of Dragons Den. But look at how that ended up.
I once heard a story about a young man, maybe in his very early teens, who complained that the songs in church were boring and irrelevant. So he started writing his own songs. Lots of them. I expect they were not well received by all at the time. But 300 years later, we all know them and many of us love them. The boy was called Isaac Watts. One of my favourites of his is 'When I survey the wondrous cross'.
When wereadthe Gospel accounts, we regularly encounter these pantomime baddies called Pharisees. The thing they are often criticised for - not least by Jesus - was their tradition, and their devotion to their traditions. They are presented as inflexible, conservative, closed-minded. But the origins of this group within Second Temple Judaism was actually the opposite to how we find them in the New Testament. This group emerged as a liberal movement, who believed that the Law, the Scriptures, did not speak for themselves in the contemporary culture, and so they started to interpret the Law, creating volumes of commentary on the Law, which became basically small print to help ensure that the Law was observed properly. So these guys were liberal, in that they wanted to make the Bible make sense in their culture. That, in fact, is a founding principal of classic Liberalism, the quest for a theology that makes experiential sense.  The trouble is, often very fluid or provisional interpretations, working theories, become cast in stone.
That's a problem we often encounter in theology. Theology is the study (ology) of God (theo). Now if one's theology never shifts, then one's understanding or experience of God doesn't either. In a sense, a theology that is closed, fixed, is presumptuous, in my view. It suggests we know all we need to know about God, or even that we know everything about God. Of course, such a presumption would usually be unconscious.
Anyway, I think theology can only ever be provisional. Like a scientific theory, if new observations, new data, disprove the theory, we can adjust it. That's not to say we give up our faith convictions. But it is to say maybe we don't need to hold tight to so many propositions.
To return to my initial point, all traditions were new once. This applies to traditionalists and progressives alike. New traditions often start as correctives to existing ones. Think of revolutions and reformations. And while we're there, let's remember that many totalitarian regimes started with revolutions. Many dictators stood for and fought for freedom first. Today's liberals may be tomorrow's conservatives. In fact, liberals can sometimes be the least liberal towards other people's views. So, not all traditions are bad, and not all change is good. But neither is all change bad, nor all traditions good. Let's be open to try new things and old ones. Let's learn from one another about faithfulness to what got us where we are, and fearlessness of what will get us to where we might go.
