Lawrence Justinian was a member of the well-known Giustiniani family, which includes several saints. The piety of his mother seems to have served as an inspiration for his own spirituality, as he chose of a life of prayer and service. In 1404, after he had been ordained a deacon, at the suggestion of an uncle who was a priest, he joined a community of canons regular following a monastic form of life on the island of San Giorgio in Alga.[2] He was admired by his fellows for his poverty, mortification, and fervency of prayer. Two years after his ordination to the Catholic priesthood in 1407, the community accepted the Rule of St. Augustine. He was chosen to be the first prior of the community.[3]

Lawrence promoted the Constitutions which he been established for the Canons of St. George, which was embraced by other communities of Canons in the region and shortly thereafter he became the Prior General of a Congregation. He was so zealous in spreading it that he was looked upon as if he were the actual founder of the Order.

In 1433, Pope Eugene IV, one of the founders of the Monastery of San Giorgio,[4] named Gustiniani as the Bishop of Castello. He found a diocese in shambles and his administration was marked by considerable growth and reform. In 1451, Pope Nicholas V united the Diocese of Castello with the Patriarchate of Grado, and the seat of the patriarchate was moved to Venice, making Giustiniani the first Patriarch of Venice, a post that he held for over four years.

It was during Lawrence's rule that Constantinople fell to Muslim forces. Due to their centuries of close trading partnerships with Byzantine Empire, the people of Venice were in panic as to their future. He took a leading role in helping the Republic to deal with the crisis, working with the Senate to help chart its future, as well as with the clergy and people to calm them.[2]


He died on January 8, 1456, and was canonized by Pope Alexander VIII (1689–1691). His works, consisting of sermons, letters and ascetic treatises, have been frequently reprinted.

Pope Innocent XII (1691–1700) inserted his feast day in the General Roman Calendar for celebration on 5 September, the anniversary of his elevation to the episcopate. Because of the saint's limited importance worldwide, his liturgical celebration is no longer included in the General Roman Calendar,[5] and his feast was moved to 8 January, the day of his death.[6]
