Around 669 Bishop Putta was appointed Bishop of Rochester.
Bede. 676. In the year of our Lord's incarnation 676, when Ethelred, king of the Mercians, ravaged Kent with a powerful army, and profaned churches and monasteries, without regard to religion, or the fear of God, he among the rest destroyed the city of Rochester [Map]; Putta, who was bishop, was absent at that time, but when he understood that his church was ravaged, and all things taken away, he went to Sexwulf, bishop of the Mercians, and having received of him a certain church, and a small spot of land, ended his days there in peace; in no way endeavouring to restore his bishopric, because (as has been said above) he was more industrious in spiritual than in worldly affairs; serving God only in that church, and going wherever he was desired, to teach church music. Theodore (age 74) consecrated Cuichelm bishop of Rochester in his stead; but he, not long after, departing from his bishopric for want of necessaries, and withdrawing to other parts, Gebmund was substituted in his place.
In 676 Bishop Putta was appointed Bishop of Hereford. There is some debate among historians as to whether there were two Putta's and whether the Putta that was Bishop of Hereford was a different person to the Putta that was Bishop of Rochester.
Around 688 Bishop Putta died.
Bede. "In the name of our Lord God and Saviour Jesus Christ, who reigns for ever and for ever, and governs his church, it was thought meet that we should assemble, according to the custom of the venerable canons, to treat about the necessary affairs of the church. We met on the 24th day of September, the first indiction, at a place called Hertford [Map], myself, Theodore, the unworthy bishop of the see of Canterbury, appointed by the Apostolic See, our fellow-priest and most reverend brother, Bisi, bishop of the East Angles; also by his proxies, our brother and fellow-priest, Wilfrid, bishop of the nation of the Northumbrians, as also our brothers and fellow priests, Putta, bishop of the Kentish castle, called Rochester; Eleutherius, bishop of the West Saxons, and Winfrid, bishop of the province of the Mercians. When we were all met together, and were sat down in order, I said, ' I beseech you, most dear brothers, for the love and fear of our Redeemer, that we may all treat in common for our faith; to the end that whatsoever has been decreed and defined by the holy and revered fathers, may be inviolably observed by all.' This and much more I spoke tending to the preservation of the charity and unity of the church; and when I had ended my discourse, I asked every one of them in order, whether they consented to observe the things that had been formerly canonically decreed by the fathers ? To which all our fellow-priests answered, ' It so pleases us, and we will all most willingly observe with a cheerful mind whatever is laid down in the canons of the holy fathers.' I then produced the said book of canons, and publicly showed them ten chapters in the same, which I had marked in several places, because I knew them to be of the most importance to us, and entreated that they might be most particularly received by them all.
