Perhaps he de-emphasize conversion because he knows that now and until the Second Coming, unless the Popes of Rome repent of their pride in declaring themselves to be the "Vicars of Christ" (as if He who promised, "Lo I am with you to the end of the age" is absent so as to need a vicar) and humbly submit to the canons and teachings of the Ecumenical Councils of the Holy Orthodox Church as they did before the 11th century, papal overtures to the Orthodox will always be met with the words St. Aleksander Nevsky used in replying to the Crusdaders who sought to reduce Holy Russia to papal rule:
"The traditions of the Holy Fathers of the Seven Councils we scrupulously keep. As for your words we hear them not. We do not want your doctrine."
These words were spoken by the saint in reply to the embassies of the Teutonic Knights before he defeated them, by the grace of God, in the Battle on the Ice.
the Popes of Rome repent of their pride in declaring themselves to be the "Vicars of Christ" All bishops are vicars of Christ, because they follow in the footsteps of the Apostles, of whom Our Lord said, "Who hears you, hears me."
That includes your bishops, too.
