10 The priest, according to the magnificent definition given by St. Paul is indeed a man Ex hominibus assumptus , "taken from amongst men," yet pro hominibus constituitur in his quae sunt ad Deum , "ordained for men in the things that appertain to God": his office is not for human things, and things that pass away, however lofty and valuable these may seem; but for things divine and enduring. These eternal things may, perhaps, through ignorance, be scorned and contemned, or even attacked with diabolical fury and malice, as sad experience has often proved, and proves even today; but they always continue to hold the first place in the aspirations, individual and social, of humanity, because the human heart feels irresistibly it is made for God and is restless till it rests in Him.
