Being in such close contact with the divine mysteries, the priest cannot but be hungry and thirsty after justice, or not feel inspired to assimilate his life to his exalted dignity, and orient his life towards that sacrifice in which he must needs offer and immolate himself with Christ. Consequently, he will not merely celebrate Holy Mass, but will live it out intimately in his daily life; in no other way can he obtain that supernatural vigor which will transform him and make him a sharer in the life of sacrifice of the Redeemer. (Papal Writings, Menti Nostrae, 23 September 1960).
