Sui generis
In local government, a "sui generis" entity is one that does not fit with the general scheme of local governance of a country. For example in England, the City of London and the Isles of Scilly are the two "sui generis" localities, as their forms of local government are both (for historical or geographical reasons) very different from those of elsewhere in the country. 
In a press conference during which reporters were trying to analyse his political personality, Huey Long said, "...say that I am "sui generus", and let it go at that."
Humani generis redemptionem
Humani generis redemptionem is an encyclical by Pope Benedict XV given at St. Peter's, Rome, on 15 June, 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.
