I do hope Catholics return to giving Holy Days their proper place. Which other ones have been transferred? Transfiguration? Annunciation? By trying to make the Days more accessible, I think their distinction has been lost; it becomes "just another Sunday."
And I pray we Orthodox will never change. As we say, "Change? What is this word 'Change?'"
Oh and I must say "Christ is Ascended!" We only get to say that until Pentecost.
Note: this lazy practice is localized to the Catholic Church in America. The rest of the Church still observes the Holy Days.
The changing of the holy days to put them on Sundays came because for the reason, and forget any mispellings, “convienence”.
