CCC 1049
Profession of Faith›SECTION TWO I. THE CREEDS›CHAPTER THREE I BELIEVE IN THE HOLY SPIRIT›VI. Hope of the New Heaven and the New Earth
"Far from diminishing our concern to develop this earth, the expectancy of a new earth should spur us on, for it is here that the body of a new human family grows, foreshadowing in some way the age which is to come. That is why, although we must be careful to distinguish earthly progress clearly from the increase of the kingdom of Christ, such progress is of vital concern to the kingdom of God, insofar as it can contribute to the better ordering of human society."
