See anything missing?

Anyone else notice the absence of a department for evangelism, or faith- sharing, in the National UCA Assembly?
Or is this part of another area listed?

Hmmm…yes indeed. Maybe evangelism in this case might come under another heading… or even a few headings. eg: Frontier Services, or Care & Community Services in a somewhat smaller way, and no doubt there would be plenty of spreading the good news while active in Disaster Relief. But yes, we are all commissioned in some way to spread the word which is among others things in “taking up our own cross”, and definitely requires it’s own place somewhere near the top of the order.
