I have placed this encyclical into the Intra-TOC Polemics as this encyclical attacks Dr. Auxentios of the Diocese of Etna and Portland as well as the Synod under Kallinikos. Dr. Auxentios has in the past complained bitterly whenever someone, especially Dr. Vladimir Moss, has attacked him.
This HOCNA encyclical is a must read. I would quote parts of it, but the pdf google drive prevents one from performing a cut and paste. This prevents me from doing a scholarly comparison with the documents from the SiR and the Kallinikos Synod that were published during the union and afterwards.
One important fact: HOCNA has now put a stop to intercommunion between HOCNA and the Kallinikos Synod.
I did not know that this was still occurring, but two hierarchs under Archbishop Kallinikos did mention this intercommunion back in 2012.
It is obvious that HOCNA is lamenting the loss of nearly half of its parishioners and parishes to the Kallinikos Synod.
Perhaps this is an attempt to gain them back.
