Note that you made no mention of the role of the Holy Spirit in any way here. I noticed it right off. This is the characteristic of those who are afflicted with "pride of intellect". To such, their thoughts alone are enough to save them, so all they need are the right words and proper understandings of the words. The need for the intercession of the Holy Spirit is forgotten about.
This is Prelest of the most awful sort. A miracle is needed to save them who become afflicted with this most foul of spiritual diseases. I am honestly hoping that you are not truly afflicted in this way so that you still learn from God about His Divine Mysteries.
Times changed, and the conditions under which the Christians live and worship have changed many times throughout the 2000 plus years since Christ established His Church. It's still the same Church. It had sinners in it causing various problems from the beginning, all throughout, and even now. There were always hypocrites practicing religion alongside those who were not hypocrites. A long robe doesn't make a person a hypocrite. Hypocrisy is in the heart.
This that I will now say is important: If hypocrisy subtly exists in our own hearts (i.e. the passion of vainglory), we will refuse to be aware of its existence in ourselves and project it onto other people whose appearance give us justification for doing so. My Lord has a saying: "Judge not, lest you be judged" (Matthew 7:2) because He knows that all such judgment springs from a heart full of evil.
If we automatically condemn a person for their appearance, it's only by the evil within our own hearts that we don't own up to. The Orthodox faith is the practice of spiritual warfare. You fight the passions in your heart and the demons bringing evil thoughts with all the weapons and protections God has given. The Holy Spirit intervenes and rewards with victory and the heart is purified. The log of passions thus being removed from your own spiritual eye, you see clearly, with Love, and can remove the splinter in your brother's eye. If you judge, you are not seeing things as they really are: you are only seeing things as you are, in your heart. I have to say this because of your "blanket" condemnation of all Christians wearing long robes. It's obvious that something is amiss in this recurring concern of yours. This is like if I refuse to wear a robe and then point at people who do and say, "see, I'm righteous because I listen to the word of God and don't go about in long robes to be seen in the marketplace to be someone special! O, how superior my spiritual qualities are to those proud hypocrites in those fancy religious garments! They are children of their father, the devil, like the Pharisees before them,while I, on the other hand, know how to live according to the law spoken by Jesus. I thank Thee, O Lord, that I am not like those Pharisees... those vain hypocrites... but I read and listen to your words and do not do the things that they do."
The Orthodox say instead... Lord, have mercy on me, the most wretched and useless of all Your servants. They are able to say this and really believe it because of the grace of the Holy Spirit, Who fills them with True humility.
