Affirming Laudianism, much like another organisation in the Anglican Church, does not expect its members to have any firm beliefs or doctrinal commitments but is solely concerned with:
1. The externals of religion
and
2. Including the ambitious.
Doesn't matter what you believe as long as it "looks pretty".
Sounds like simiolar to Affirming Catholicism.
It's a bit of a jest, if you read the piece on Laud himself. "Affirming" he was not.
