Gregory the Great — as excerpted in the Catena Aurea on Matthew 25:14-30

“(ubi sup.) But there are many within the Church of whom this servant is a type, who fear to set out on the path of a better life, and yet are not afraid to continue in carnal indolence; they esteem themselves sinners, and therefore tremble to take up the paths of holiness, but fearlessly remain in their own iniquities.”
