But sometimes a man falls from proficient charity, and rises again to incipient charity. Therefore man always rises again to less virtue.

Context

“Therefore a man rises to greater grace or charity than that which he had before; which is confirmed by the Apostle's words (Rom. 5:20) : "Where sin abounded, grace did more abound." On the contrary, Charity whether proficient or perfect is greater than incipient charity. But sometimes a man falls from proficient charity, and rises again to incipient charity. Therefore man always rises again to less virtue. I answer that, As stated above (Q. 86, A. 6, ad 3; Q. 89, A. 1, ad 2) , the movement of the free-will, in the justification of the ungodly, is the ultimate disposition to grace; so that in the same instant there is infusion of grace together with the aforesaid movement of the free-will, as stated in the Second Part” source
