Visiting Northumbria, he charged Chad with not being duly consecrated. The saint replied with great humility, "If thou knowest that I have not duly received the episcopate, I willingly resign the office, for I never thought myself worthy of it; but, though unworthy, I consented to undertake it for obedience sake." Theodore hearing his humble answer, said that he should not resign the episcopate, but he himself completed his ordination again after the Roman manner. He probably advised Chad to resign his see to Wilfrid, for we next hear of our saint in retirement at Lastingham. In 669, Jaruman, bishop of the Mercians, died. King Wulfhere asked Theodore to send them a bishop. The archbishop did not wish to consecrate a fresh one, so he begged King Oswy to let Chad, who was then at Lastingham, be their bishop. Theodore knowing that it was Chad's custom to go about the work of the gospel on foot, rather than on horseback, bade our saint ride whenever he had a long journey to perform, but, finding Chad unwilling to comply, the archbishop with his own hands lifted him on horseback, for he thought him a holy man, and obliged him to ride wherever he had need to go. Though Chad was bishop of Lindisfarne for so short a time, he left his mark on the affections of the people, for we find that at least one chantry was dedicated in his name at York Minster. Soon after his election to the bishopric of the Mercians, he set out for Repton in Derbyshire, where Diuma, the first bishop of the Mercians, had established his see. Whether our saint desired a more central position for the episcopal see, or was influenced by the wish to do honour to a spot enriched with the blood of martyrs, Bede does not tell us, but Chad established the Mercian see at Lichfield, then called Licetfield, or the Field of the Dead, where one thousand British Christians are said to have been put to death. His new diocese was not much less in extent than that of Northumbria. It comprised seventeen counties, and stretched from the banks of the Severn to the shores of the German Ocean. Theodore, years afterwards, detached from it the sees of Worcester, Leicester, Lindesey (in Lincolnshire), and Hereford. Though it was far beyond the power of one man to administer it effectually, yet Bede witnesses that "Chad took care to administer the same with great rectitude of life, according to the example of the ancients. King Wulfhere also gave him land of fifty families to build a monastery at the place called Ad Barve, _i.e._, 'At the wood,' in the province of Lindesey, wherein monks of the regular life instituted by him continue to this day." "Ad Barve" is conjectured by Smith, of Durham, to be Barton-on-Humber, where there is still standing a very ancient church, admitted by Rickman to be partly Saxon, dedicated to S. Peter.
