This phrase is from the Godly Play lesson about the Holy Family, written by Jerome W. Berryman. It says that the Christ Child grew up to be a man and died on the cross. That is very sad, but it is also wonderful, in an Easter kind of way. Now... he is everywhere, and in every time.
It's a beautiful rendition of the circle of the church year in all its colors, along with the corresponding dates from the calendar year. If I had loads of time (which I don't) it would be tempting to try to put together something similar to this myself, with tweaks (such as purple for Advent) to bring it into line with our congregation's practice. But as it is, perhaps I will just print this out to have in the room as a talking point. A high-quality pdf is here. Many thanks for Jenifer Gamber for making this available to churches!
