The matter in which there might be spiritual progress in time on a time-span extending over many successive generations of life on Earth is not the unregenerate nature of man, but the opportunity open to souls, by way of the learning that comes through suffering, for getting into closer communion with God, and becoming less unlike Him, during their passage through this world.

What Christ, with the Prophets before Him and the Saints after Him, has bequeathed to the Church, and what the Church, by virtue of having been fashioned into an incomparably effective institution, succeeds in accumulating, preserving, and communicating to successive generations of Christians, is a growing fund of illumination and of grace-meaning by ‘illumination’ the discovery of revelation or revealed discovery of the true nature of God and the true end of man here and hereafter, and by ‘grace,’ the will or inspiration or inspired will to aim at getting into Him. In this matter of increasing spiritual opportunity for souls in their passages through life on Earth, there is assuredly an inexhaustible possibility of progress in this world.
