What were the main differences between the Irish and Roman traditions of the Church as discussed in the chapter?

The main differences between the Irish and Roman traditions of the Church were the fashion of the tonsure and the time of keeping Easter.

While the Irish and Roman traditions of the Church shared many core beliefs and practices, such as the threefold ministry and the celebration of the Eucharist, they differed in the fashion of the tonsure and the time of keeping Easter. These differences, although seemingly minor, had significant implications for the future of the Church in England and Scotland. The Synod of Whitby in 664 was convened to settle these issues, ultimately leading to the adoption of the Roman practices in Northumbria, marking the decline of Celtic influence in the region.
