Section 2. Names of this Sacrament — In explaining what is more necessary on this subject we shall follow almost the same order observed in the exposition of the other Sacraments. Hence we shall first show that this Sacrament is called Extreme Unction, because among all the unctions prescribed by our Lord to His Church, this is the last to be administered.
