yes Severian as the link states , His Grace is defending the Orthodox Faith against certain people's foreign teaching that created turmoil in the Church. He affirms that the Theotokos, is born like all the rest of humanity, the only one who is born without ancestral sin is the Lord alone. he talks in a most wonderful way about what the Orthodox Church have taught for all this time. May God grant him long, healthy life to continue to serve the Church as he does now.
I hope this briefly answers what you wanted verified.
