I was wondering if anyone could help me out. I am very curious about the United Church of Tonga, so could anyone explain to me the history of the UCT, how it started, who started it, and where?
I've also noticed that the UCT uses the Tohi Himi SUTT, but it's church ministers wear the long coat and pants, just like the Siasi Tonga. Does that mean that it is a mix between the SUTT and Siasi Tonga?
Anyways, 'ofa atu kiate kimoutolu kotoa pē.
