The Synod of Whitby, convened in 664, was a pivotal moment in early Christianity in England, addressing the conflicting practices of Easter celebration between the Scots and the Roman church. Led by King Oswiu and Abbess Hilda, the synod gathered bishops and clergy to resolve the discord and reaffirm a unified Christian doctrine. Prominent figures such as Colman, who defended the Scottish tradition, and Wilfrid, who advocated for the Roman customs, presented their cases. Ultimately, the synod sought to establish a common practice for the celebration of Easter, reflecting the broader efforts to unify Christian observance in the region.
