"The average Catholic's task" (in your words) for the next four years is the same as it's always been. It is to love God and to love our neighbour.
There is no need to find a list of imagined "lost virtues". Jesus explained what to do. He taught us this:- “You shall love the Lord, your God, with all your heart, with all your soul, and with all your mind. This is the greatest and the first commandment. The second is like it: You shall love your neighbor as yourself" [Matthew chapter 22].
He also taught us how to love our neighbour. He said that we should show pity to those who are in need of help. Thus the Samaritan was a good neighbour to the man who fell into the hands of bandits [Luke chapter 10].
Recognise who are the bandits. Recognise who who have fallen into the bandits' hands. Help the latter.
