From Eric Mascall:
"It has often been pointed out ... that the idea of a liturgy as something composed by a committee and then imposed by authority is a very novel one. Its first appearance seems to be in England in 1549, though it was followed soon after in the Roman Church with the issuing of the Pian Missal in 1570. In all the great periods of liturgical development the governing factor was the liturgical consciousness of the worshipping Church, though synods and even secular rulers might exert a more or less wholesome influence upon it, as, for example, Charlemagne and the Byzantine emperors."
I would add a couple of qualifications to this:
(1) The Pian Missal of 1570 had very few differences from what went before ... you could have continued to use your old books ... while Cranmer's 1549 Prayer Book was an overnight radical change ... you could not have used your Sarum Missal from yesterday without breaking the Act of Parliament enjoining the Prayer Book.
(2) The technological advance of Printing was/is necessary to put a new committee-liturgy into immediate, enforced, country-wide effect.
