It is not meant to be superficial…or clever. It is a fact that we do not subscribe to the 1854 RC doctrine. And we see her as the great example of asceticism and holiness.
I have it. And I am quite familiar with the great veneration we ascribe to the Most Holy Theotokos.
But we still don’t see her as an exception by being spared from ancestral sin (IC).
I was pretty sure that you have the Menaion…

…and that you’ve used it as well. I have the Triodion and Supplement but I so dearly wish for the Festal texts. Someday…eh?
At any rate, I know that there is no specific reference to an immaculate conception, but there are references to her becoming as a person and that is the Catholic Christian understanding of conception: the moment of becoming as a person. There are references to her holiness being far more exceptional than any other human being. There are references to the ancientness of God’s intentions for her exceptional holiness.
All of these things convey the primary and fundamental message of the Immaculate Conception.
The actual teaching of the immaculate conception is quite narrow, and has to be taken with other Marian teachings which indicate that the Mother of God was fully human with a fully free will in order to be understood in its proper perspective: which is that the Mother of God was fully illumined [bore the grace of original justice] at the moment of her becoming a person, by a particular act of God’s grace.
That does not mean that she cannot be tempted; it does not mean that she cannot choose to conform herself to God’s grace. It does not set her apart from the ascetic life. In fact, her whole life was an exercise in self-emptying, by grace. If any part of our lives are self-emptying, it is also by grace. So there is NO immaculate exception in any regard except for the fact that she is: as it is told in the liturgy of her presentation into the temple, remarkable graced by God from the very moment of her becoming an individual soul, and that the holiness she bears surpasses the holiness of any other human being in the history of mankind.
I don’t mean to demean you Mickey and I am sorry I poked at your initial statement. But the idea that the immaculate conception is something strange is not born out in terms of Orthodox liturgies.
It is one of the things that we would all be blessed to not fight about.
