When Charles Martel drove
Saint Rigobert from
Reims, Milo was appointed his successor. As bishop, Milo became a controversial figure for the Church. His avarice and fondness of earthly pleasures soon placed him in opposition with the church. Milo habitually used church property for his personal and political purposes, usually to indulge his illegitimate sons. He accumulated much of the riches of his dioceses and developed a reputation for corruption.
Pope Zachary counseled Boniface about dealing with disreputable prelates such as Milo. "As for Milo and his like, who are doing great injury to the church of God, preach in season and out of season, according to the word of the Apostle, that they cease from their evil ways." Accounts of Milo's time as bishop are collected in the
Gesta Treverorum. ==Deposition==
