ACC ~ Galatians 4 v26
HOW WE ENTER THE HEAVENLY JERUSALEM IN THIS LIFE. AMBROSIASTER: Jerusalem, which he calls our mother, represents the Lord’s mystery, through which we are reborn into freedom, just as she is free. And she is called heavenly because heaven is her seat. Those to whom she gives birth will be there with her. EPISTLE TO THE GALATIANS 4.26.
THE FOURFOLD MEANING OF JERUSALEM. JOHN CASSIAN: One and the same Jerusalem can be understood in a fourfold way: historically as the city of the Jews, allegorically as the church of Christ, anagogically as the heavenly city of God, which is the mother of all, and tropologically as the human soul, which is often upbraided or praised under this name by the Lord. CONFERENCES 14.8.4.
