Christianity fully based on Persian culture instead Roman

What would be the Christian world, if Christianity was based on Persian culture instead of Roman-Greek?
One can assume two scenarios:
- Palestine was gained by Persians and Christianity from their beginnings was growing in Persia, first as a persecuted religion, after them maybe would moving up to a higher level.
- As result of the stronger persecutions of Christians, they would have found a better place for main center somewhere in Persia. Then, after the cessation of persecution returns to the Empire bringing with it elements of Persian culture.

How such events could bounce in the short term on the history of Europe? Are then Christianity could have a chances to dominate Rome as in OTL?
 
Isn't there a TL where the principle center of Christianity becomes Persia and not Rome? Patriarch of Patriarchs or something like that it's called.
 
OK, but mostly here I am referring to some of the cultural elements from Persian culture, including polygamy and much wider gender equality.
Supposedly one of the patriarchs of Seleucia had many wives.
Even more interesting issue is the freedom of women: the existence of female troops and the possibility of promotion to the rank of general for women. Just prior to the Arab invasion of Iran, the country's independent power exercised two queens.
Does any of these elements can would enrich the culture of the Persian Christians, or as in the case of OTL Christianity, inspired by Greco-Roman culture - women's freedom would be taken away?
 
Polygamy would still be frowned on by Christians in Persia, so expect the Sassanids to place a ban on it. Gender equality and religious tolerance could also enhance the culture of Persian Christianity, though I suspect that they may also include significant influences from Zoroastrianism. Slavery though, would not occur.
 
If the Christianity based on Persian culture was developed in place of a Roman based Christianity, the Gregorian Calendar of the OTL would have been replaced by an Iranian Calendar. The Solar Hijri Calendar used in Iran has developed from ancient Persian calendars and it is said to be the most accurate solar calendar.
The Solar Hijri Calendar starts on the spring equinox day, March 21. There are twelve months and the first six months have 31 days each. The next five months have 30 days each. The last month Esfand has 29 days in normal years and 30 days in leap years. The new year day is called norooz and is a very important festival in Iran.
