Isn't "churchianity" about who gets the glory? And what the giver of the glory gets?
Some people spend practically their entire Sunday in church, attending every service. Why? Do they really need five services every Sunday? Or is it to feel good? Or be seen to be there? Maybe those people also give out the hymn books or collect up something afterwards or put the chairs away. Some people like to be chalice assistant, or to read the lesson from the Bible. Why? What's their motivation? To be seen doing it? Or because there's a need that they can fulfil, in part or whole?
What do these people do on other days? Do they help those in need, minister to the poor in some way, visit prisons, help out at hostels, etc etc? Does their Sunday church time spill into heartfelt actions during the rest of the week? Does what they learn(?) on Sunday carry through into actions in the days following?
What is it that they like about church, anyway? Is it the message, the corporate worship, the being with other Christians and sharing their faith together? Or is it the comforting ritual of the orderliness of a service? Of the sounds, smells, robes? Perhaps such are of genuine help to some people in their faith.
Whatever. I see churchianity as being those people who attend church because it's "what they do," but without it having any impact on their day to day life. Who obey rules from the church that were never even hinted at in the scriptures.
Corporately, I see churchianity as having rules that don't benefit the congregation. Ministers have to be dressed a certain way. Some people can be licensed to perform certain actions - like chalice assistant, or reading from the Bible. And so on.
Who makes these rules? And why? To what purpose?
Rules are good. But when rules take over, then they are not good. And thus, churchianity is born.
