I cannot answer for the errors and pride of Roman titles, this you must ask of them.
"And, behold, one came and said unto to him, Good Master, what good thing shall I do, that I may have eternal life? And he said unto him, Why callest thou me good? there is none good but one, that is, God". Gospel according to the Holy Apostle Matthew, Chapter 19, verses 16 - 17. King James Version
The Elder Philotheos (Zervakos) writing on 24 February, 1968 from Paros
.......When our Lord Jesus Christ, who a Perfect, Sinless man and Perfect God, was addressed by a lawyer as 'Good Teacher', He did not accept it, but rather said to the lawyer: Why callest thou me good? there is noe good but one that is God.
He goes on.......
The Patriarch consents to be called 'His All-Holiness'; and while people call God Holy - 'Holy God' - the Patriarch does not condescend to be 'Holy', but even higher than God - 'His All-Holiness'. There is nothing worse.
They both (the Pope and the Patriarch) suffer from Luciferian pride; and pride is the treasury and strongbox of all evils, sins, delusions, and heresies.
Christ said, "Learn of Me, for I am meek and lowly in heart, and ye shall find rest unto your souls"
The Pope and the Patriarch have not accepted lessons from Christ. They have taken lessons from Lucifer. "Learn of me, for I am proud, for I will be like the most High".
The thread I originally was reading, and unrelated, contained a reference which triggered my question and then a recollection of coming across Father Philotheos response. Father Philotheos writing here appeared (in Greek) in Holy Philotheos of Paros, No 13 2005 and later in English elsewhere.
Reading the Gospel, wondering and later Elder Philotheos writing and having long been troubled by the pompous titles of not a few ecclesiastical titles, Orthodox (and Roman) is my reason for the post.
