American 1928 Revisers keeping the ‘national church can do whatever’ ball rolling.
Some selections both of Epistles and Gospels which seem less happy have been emended in various recent Prayer Book revisions, as we shall see. While such changes are sentimentally regrettable, as putting sister branches of the Anglican church out of step with each other, and with Western traditions of some eleven hundred years, on certain occasions, yet plainly there is nothing in the history of our liturgical lectionaries which entitles them to more respect than their intrinsic merits deserve; and it is quite within the competence of any National Church to make such further improvements as may be demanded in the lections for our cycle of Sundays.
