You have to go back to the 70’s when the ‘Big-Split’ happened and trace it from there.
I’ve said it a few times on here, and will say it again…
The Traditional Anglican Communion (TAC) is the largest and with a college of bishops, the most authoritive in matters of faith and morals as concerns orthodox doctrine.
Although many of the smaller bodies (APCK being one of them) have held on to orthodox doctrine as far as I know, they are scattered and often only have one or a few bishops presiding over their diocese and parishes. Hopefully they will come into the fold (the way things are looking, it is only a matter of time for many of them).
There are many who guise themselves in traditional Anglican liturgy and garb, yet who ordain and continue to ordain women, and thus opening the floodgates for every other danger and heresy to come through.
And the Roman Catholic apologists are absolutely correct in asserting that Anglicans who have abandoned the Deposit of Faith yet continue with liturgical pleasantries are indeed engaging in nothing more than ‘smells and bells’. For shame…the lot of them.
