Laurence was one of the first missionaries to the Saxons, who came over with S. Augustine; and he succeeded the Apostle of England in the see of Canterbury [a bishop’s “see” is his diocese, named from his seat (Latin sedes)], in 608, in which he sat eleven years. Bede [English monk and historian (d. 735)] says, "Laurence succeeded Augustine in the bishopric, having been ordained thereto by the latter, in his lifetime, lest, upon his death, the state of the Church, as yet unsettled, might begin to falter, if it were destitute of a pastor, though but for one hour. Wherein he followed the example of the first pastor of the Church, Peter, who, having founded the Church of Christ at Rome, is said to have consecrated Clement his assistant in preaching the Gospel, and at the same time, his successor. Laurence, being advanced to the degree of archbishop, laboured indefatigably, both by frequent exhortations and examples of piety, to raise to perfection the foundation of the Church, which had been so nobly laid. In short, he not only took care of the new Church formed among the English, but endeavoured also to employ his pastoral solicitude among the ancient inhabitants of Britain, as also among the Scots, who inhabited the island of Ireland. For when he understood that the course of life and profession of the Scots, as well as that of the Britons, was not truly ecclesiastical, especially that they did not celebrate Easter at the correct time, he wrote jointly with his fellow-bishops, an exhortatory epistle, entreating and conjuring them to observe unity of peace, and conformity with the Church of Christ spread throughout the world."

But soon troubles arose which obliged Archbishop Laurence to withdraw his attention from the British bishops to the condition of his own Kentish diocese. The pious King Ethelbert died, and his son Eadbald, instead of following his father's example, opposed Christianity, and caused great scandal by taking to him his step-mother to wife, his own mother, the saintly Bertha, having died some years before. The condition of Christianity became so hopeless in Kent, that Laurence resolved to desert his see, and he was confirmed in his determination by Mellitus, bishop of London, and Justus, bishop of Rochester, who fled from the violence of the sons and successors of the Christian Sebert, king of the East Saxons. Bede says, "Laurence, being about to follow Mellitus and Justus, and to quit Britain, ordered his bed to be laid, the night before, in the church of the blessed Apostles, Peter and Paul; wherein, having laid himself to take some rest, after he had poured out many prayers and tears to God for the state of the Church, he fell asleep. In the dead of the night, the blessed prince of the apostles appeared to him, and scourging him a long time with apostolic severity, asked of him, 'Why he would forsake the flock which he had committed to him? or to what shepherds he would commit Christ's sheep that were in the midst of wolves? Have you,' said he, 'forgotten my example, who, for the sake of those little ones, whom Christ recommended to me in token of His affection, underwent at the hands of the infidels and enemies of Christ, bonds, stripes, imprisonment, afflictions, and lastly, the death of the cross, that I might be crowned with Him?' Laurence being excited by these words and stripes, the very next morning repaired to the king, and taking off his garment, showed the scars of the stripes he had received. The king astonished, asked, 'Who had presumed to give such blows to so great a man?' and was much frightened when he heard that the bishop had suffered so much at the hands of the apostle of Christ for his salvation. Then, abjuring the worship of idols, and renouncing his unlawful marriage, he embraced the faith of Christ, and being baptized, promoted the affairs of the Church to the utmost of his power."

In the reign of this same king, Archbishop Laurence died, and was buried in the Church of S. Peter, close beside his predecessor Augustine, and was succeeded by Mellitus.
