Humani generis redemptionem is a encyclical by Pope Benedict XV given at St. Peter's, Rome, on June 15 , on the Feast of the Sacred Heart of Jesus in the year 1917, in the third of his Pontificate. The encyclical points to an ever increasing number of Christian preachers and an ever decreasing effect of their preaching. He admonished bishops to be preachers first of all, and to be more careful in the selection of preachers and confessors, for whom Humani generis redemptionem prescribed basic preconditions.
