She arguably accomplished more than any before her to conform the church of the Picts and Scots (Culdee and Columban) to the Roman church.
Before her, no one in Scotland was celebrating Sunday or following the Roman Calendar. Saturday Sabbath and Hebrew Feasts were the norm.
I quoted half a dozen mainstream history books that highlighted this topic in my book “Sabbath in the Orthodox Church East and West“. Lately I was re-reading the book “The Early Scottish Church” by MacLaughlin (who I didn’t quote in it), as found here: “The Early Scottish Church – Ecclesiastical History of Scotland”(Free PDF Book) by McLaughlin, Edinburg 1865, and McLaughlin (like the dozens of other great books on the topic said it quite well.) He dedicates a lot of pages just on how St Margaret influenced and changed the church. The Saturday Sabbath and Calendar is at the top of the list.
