An example of the four different senses (namely, the _literal_, the _allegorical_, which appeals to our faith, the _moral_, and the _mystic_) in which a word or passage of Holy Writ may be interpreted is offered in the term "Jerusalem." If we read that "they went up to Jerusalem every year," we understand the word Jerusalem to represent the chief city of the Hebrews, situated on the confines of Judah and Benjamin. If we happen upon the passage of St. John where he says: "I, John, saw a holy city, the new Jerusalem, coming down out of heaven from God; ... behold the tabernacle of God with men, and He will dwell with them," we know that this _new_ Jerusalem on earth can be no other than the Church, where God has His tabernacle, dwelling with men. The word is used _allegorically_, that is to say, it appeals to our faith; to the internal, not to our external sense. Again, the word "Jerusalem" may be used in the sense which its etymology suggests without reference to any city. Etymologically it consists of two words, signifying _foundation_ and _peace_. A rabbi might, therefore, bid his disciples to strive to build up "Jerusalem," meaning that they should seek to lay solid foundations of peace by conforming their lives to the law of Jehovah. This would give the word Jerusalem simply a _moral_ signification. Finally, the word is used as a synonyme for "heaven," as in Apoc. xxi. 10: "And He took me up in spirit, ... and He showed me the holy city Jerusalem, ... having the glory of God." Here we have the term in its _anagogical_ sense, that is, referring to the future life. Without entering into the various figures of speech with which the language of the Hebrews abounds, let me suggest some points which must be observed in order that the true sense of the Sacred Scriptures may not escape us so as to mislead the mind.
