Wilfrid the Holy was an influential Anglo-Saxon bishop and missionary in the 7th century. Born around 634 in Northumbria, he played a key role in spreading Christianity throughout England. He is best known for his efforts to establish the Roman form of Christianity in the region, which included advocating for the observance of Easter on the correct date. Wilfrid became the Bishop of York and was a prominent figure in the Synod of Whitby in 664, where he argued for the Roman practices over the Celtic traditions. His dedication to the church and his missionary work earned him the title "the Holy."
