Who is "they?" Certainly not God.... certainly not THE CHURCH.
Yes, there were 3 local, regional, nonauthoritative meetings around 400 that indicated what books are to be included in the lectionary for those areas, but that has NOTHING to do with anything remotely related to this topic or the ENDLESS number of virtually identical threads you two keep starting. Lectionaries are not canonical - never have been, still aren't. And since NO ONE agreed with these 3 regional, nonauthoritative, western synods, the point is irrelevant even to the lectionary. WHO CARED what these meetings said? Not any church in the East.... for 1000 years, not the RCC.... Indeed, until the RCC "discovered" them in the 16th Century, they were not even mentioned - entirely forgotten.
BUT I'm interested in knowing you accept all church meetings..... thus of course you accept Indulgences, Purgatory, the Infallibility of the Pope, the Perpetual Virginity of Mary because all those also came from Councils - not just regional, nonauthoritative synods but actual authoritative Councils. You consider them to be the infallible Voice of God and the Definitive Authoritative Determination of THE CHURCH. Obviously. I mean, why accept one tiny regional meeting that had no impact on anything because it had no authority as an authoritative decision of THE CHURCH but not bigger, more important,much more accepted councils?
