No, but the Church did at the First Ecumenical Council, and only on Sundays, precisely because everyone was making up their own rules.
Some habits die hard I see. Certainly there was no mention of sitting in the Church either.
Making up rules as one goes along and ignoring Ecmenical Councils is what caused the corruption and split. The same thing happened in the 16th century when Christianity splintered one more time over what appearted to have been man-made rules.
And you guys think we are juridical?! Don't you have pious customs that developed over time from inspiration that aren't precisely spelled out in council documents or episcopal declarations/pronouncements? As Benedict XVI said in one of his interviews, the Church does not proclaim a bunch of "No"'s, but rather encourages one to say "Yes" to God and experience the freedom that accompanies submitting to God's will (of course, BXVI said it much more eloquently).
The Pharisees followed all the rules (the letter of the law) and Jesus called them whited sepulchers...
