The true original church 33 A.D - 133 A.D) (A full 100 YEARS) did not have:
1) Icons (prove it if you think so, show me! - I want to SEE IT)
2) An iconostasis
3) A discos
4) A spear for the prosfora
5) Table of Oblation
6) A chalice
7) Byzantine king garb
Fanatical repetition of prayer (Jesus prayer) - held with prostrations
9) Confession only to priests
10) Processions
With a loving heart for you brother, I struggled with these things in my early orthodox life as well. The solution i found out was though much more necessary.
Remember that the orthodox church does not in any way keep the idea that, just because something is old, it´s true. Authority was given, and was used to further develop the church, and is today used to spread Gods grace through it.
For example, just the bible would not get through your list. Believe me the bible as a collection of Gods true scriptures came in the year around 400, a lot after 33 A.D. The trinity, you probably need to profess it by your list in the things in 33 A.D won´t allow it. Without the church and its authority, who can explain the validity of scriptures? Don´t take for granted that all things were sorted out within the lives of the apostles. The ground was firmly established...
As i said before dear brother, the church was given authority to just do what it did. Define the trinity in terms, so that we in Gods grace through his church could develop it.
The question is never about something old, but rather of the authority given then, to be used over time. When you exclude the church and its authority as a working hand of the Holy spirit, then you exclude everything. You can´t even give yourself authority, as if you were a apostle in the year 33 A.D, to say that something has to be old to be true. You need to be given that authority, the orthodox church is that living organism until this day. That´s why every single ecumenical council ended with the words:
It´s seems right to us THROUGH AND WITH the Holy Spirit to etc.
Whatever the church you would chose to attend to, remember this. That TRUE church need some kind of authority, or else Gods people would, and will be hurting a lot in the free open market place of ideas nowadays.
The question you ask to anyone who utters a single interpretation or word of the bible is simply this:
Who gave you authority to even interpret this verse or idea this way rather than the other?
Believe me, the orthodox, apostolic and catholic church is the only one who firmly can answer with, Christ gave us that authority 2000 years ago. It has been passed through until this day.
The issue is not old versus young, rather that the church lived out its authority in many different ways. It always used icons and can with its authority chose to stop using them.
The question is rather what authority one have to say that icons, veneration, apostolic succession, Confession only to priests, Processions, Fanatical repetition of prayer(Jesus prayer) and the entire list is wrong.
