YouTube YouTube A landmark meeting in the 7th Century called The Synod of Whitby to decide what form of Christianity should England and the subsequent English Speaking World take? In the end, Roman Christianity won out, but what is Roman Christianity and Celtic Christianity? Do they both believe in Jesus and of God? https://chrisduffett.com/2016/03/17...sm-how-christianity-can-reach-the-west-again/ Where the dates for Easter were decided. https://www.english-heritage.org.uk...y-and-stories/easter-and-the-synod-of-whitby/
Perhaps it was four decades ago that I read that St. Patrick observed the Jewish Sabbath as opposed to Sunday, (at least for a number of years during his ministry). My guess is that Celtic Christianity was less anti-Semitic in flavour than Roman Catholicism. Protestant Reformer Martin Luther was Roman Catholic before he began his own church. His tendency to be anti-Semitic is obvious in this article that he wrote in 1543. This article by Protestant Reformer Martin Luther prepared Germany for the Holocaust of the Nazi era. https://www.jewishvirtuallibrary.org/martin-luther-quot-the-jews-and-their-lies-quot
Of course both do. I would be interested to hear more about Celtic Christianity. And there are more versions of Christianity than just Roman and Celtic.
