Interruptions mean different things. When it's a channel change in the middle of your show, it means your four-year old niece has found the remote. When it's a video you can't click through, it means the advertiser spent some serious money to get your attention.
Starting all the way back with Advent, there's been a flow to the readings. Whether it's a one-off moment or a longer story, all or it fits into a larger narrative. For months, everything's been in this "and-here's-what-happened-next" rhythm.
And then there's Trinity.
At first glance, it feels random. Like it was just kind of thrown in. Like an interruption.
But sometimes an interruption isn't really an interruption. More on this tomorrow.
