Bishop Diogo Correia Valente was a Jesuit missionary. He was appointed Bishop of Japan in 1617. In the following year he took his first trip to the Far East. As there was a persecution in the Japanese Church, he was forced to stay in Macao to assist in the Epsicopal affairs. In 1632 he was appointed the Diocesan Administrator, managing the diocesan matters in Macao. He died in 1633 and was buried in St. Paul's Church. When that church was destrayed by fire, his relics were transferred to the Cathedral.
