Short answer: No.
Long answer: Where did you find this deacon?
I would also ask Where did you find this Monk?
a monk who would say its one thing what the outer church believes and another that is whispered among ourselves. i find this saying odd as it refers to the faith of the Church , in the Orthodox Church what is whispered in our homes is also proclaimed from the rooftops. even so lets just say for argument sake that there are those individuals who claim to be followers of the orthodox faith and yet they are in reality confused gnostics like Marcion or some such heretic, be it clergy or laity.the moment they stopped confessing the Orthodox faith they cease to be Her confessors period! is that new ? does that mean we have to question what the church herself is saying when she confesses her faith in the orthodox way.I do not think there is such a thing as a hidden belief that the church harbors so this assumption itself is a heretical assumption one that will lead to schismatic ideas very easily.it is true that there were heretics in the Church's history before and there will be in the future, yet the Truth the Armenian Orthodox Church confesses Along with all the Orthodox faithful will remain The Same until the return of Her Bridegroom. those who claim to be under her yet confess somethingelse the Church has a name for them, been used for 2000 years now..'heretics!' May the Lord help them see the error of their ways and help them return to the One True Faith. Amen.
if I were to meet a protestant pastor preaching the intercession of saints and the communion of saints.. i would not say wow the protestant church is suddenly becoming orthodox! I will just say that this particular pastor is speaking in direct contradition of the protestant faith.
