Exposition of the Faith

It is to be observed that there are two appropriations: one that is natural and essential, and one that is personal and relative. The natural and essential one is that by which our Lord in His love for man took on Himself our nature and all our natural attributes, becoming in nature and truth man, and making trial of that which is natural: but the personal and relative appropriation is when any one assumes the person of another relatively, for instance, out of pity or love, and in his place utters words concerning him that have no connection with himself. And it was in this way that our Lord appropriated both our curse and our desertion, and such other things as are not natural: not that He Himself was or became such, but that He took upon Himself our personality and ranked Himself as one of us. Such is the meaning in which this phrase is to be taken: Being made a curse for our sakes.
