One of four holy brothers who became priests, Chad left his home in
Northumbria to study under St. Aidan. After returning to York from
Ireland to become abbot of Lastingham, Chad unwittingly became the
center of a controversy. While Prince Alcfrid's choice for bishop of
Lichfield, St Wilfrid, was delayed in Paris awaiting consecration, King
Oswy appointed Chad in his place. As bishop, Chad traveled on foot
through his diocese to instruct people in cottages and castles, in
churches and open country. When the new archbishop of Canterbury, St
Theodore, arrived in England he decided that Wilfrid was the rightful
bishop. Chad replied that he willingly resigned as he never thought
himself worthy of the office. Theodore was so impressed by this humble
response that he later appointed Chad bishop of Mercia.
