Little is known of Pope Saint John I's life before he took office as pope, except that he was born in Tuscany.

He was just standing there, not doing anything special. As a Syrian priest he must have felt a little out of place among the Roman people mourning that day for the dead Pope. As a good preacher, he must have wanted to speak to the funeral procession about Christ's promise of resurrection. As a learned man, he must have wondered who would follow the holy Saint Gregory II as Pope and where he would take the Church. As a holy man, he must have been praying for Gregory II and for all the people around him to find their place after death in God's arms. But he was just one of the crowd.
He was the author of a volume of sermons and commentaries on a part of the Gospel of Saint Matthew, the Psalms, the Book of Job and the Apocalypse.
