None of this rises above what I term the chronologically trivial.
The Church had no doctrine which was affected by chronology,
so it could afford to be flexible. This did not extend to doctrine
itself, as illustrated by the fact that numerous Pagans had been
converted to Arianism before entering the Roman Empire, where
Arianism was heretical. Here the Church showed no flexibility,
and it was the former Pagans who conformed.
This and your preceding comments could use some citation.
It so happens that the most significant of all Pagans, the Romans,
enjoyed over 200 days of holidays per year:
Ancient Roman Holidays & Festivals
Since most if not all of these Roman holidays possessed religious
significance they would not have been tolerated in their original
form by the early Church. Therefore, you must in order to carry
your point document some form of accommodation made by the Church.
My point is that there is not any theological justification for choosing
one chronology over another.
“My experience” means you have lived through the events yourself.
What relevant events have you lived through yourself? Reading a
jargon-laden text does not count.
As to our argument, recall that for well over two centuries the Church
provided one of the best examples in all history of opposition to what
your text might label the power structure. That structure itself was one
of the best examples in history of a great empire in its prime. That empire
probably actually did throw Christians to lions. Yet it was the Christians
who in the end not only survived but triumphed. And they did not do so
by agreeing that the Romans could keep their 200 holidays per year, I don’t think.
I do not see the relevance of this to relative importance of chronology and theology.
