The Venerable Bede will writes of Pope Boniface' Vs affectionate concern for the English Church.

The "letters of exhortation" which he is said to have addressed to Mellitus, Archbishop of Canterbury, and to Justus, Bishop of Rochester, are no longer extant, but certain other letters of his have been preserved.

One is written to Justus after he had succeeded Mellitus as Archbishop of Canterbury in 624, conferring the pallium upon him and directing him to "ordain bishops as occasion should require."

According to Bede, Pope Boniface also sent letters to King Edwin of Northumbria in 625 urging him to embrace the Christian faith, and to the Christian Princess Æthelburg of Kent, Edwin's spouse, exhorting her to use her best endeavors for the conversion of her consort.

He is buried in St. Peter's Basilica on October 625.
