For those who find the CANA situation in ACNA and the Church of Nigeria perplexing, Matt and Anne Kennedy in their Preventing Grace podcast have the best explanation I’ve heard (beginning after around 8 minutes).
To rehash, the three CANA dioceses, by agreement between the Church of Nigeria and the Anglican Church in North America had to choose which of the two provinces to stay in. CANA East chose ACNA and therefore changed their name, to the Anglican Diocese of the Living Word. CANA West and the Diocese of the Trinity will be staying in the Church of Nigeria.
Sadly, there has been some heat during this process. But I will let the Kennedys discuss that.
