We, the baptized, were all given new birth, and all have the Holy Spirit, with Sanctifying Grace infused in our souls. It is identical to that Sanctifying Grace infusing the Saints, no less. What is the difference? Growth in the use of that Grace, in using the Virtues that are now part of us by the presence of this Spirit of Christ. They did their doings virtuously, whatever their daily doings were.
You are what they were, in your soul - a new creation, and new creature. So, try it out - “I am going to do this thing I am doing virtuously.” with each thing you do.
Are you driving to work? “I am going to drive virtuously”. Are you making supper? “I am going to prepare the meal virtuously”. Are you talking to a co-worker? “I am going to talk and act virtuously to this person right now.” Are you shopping? “I am going to shop virtuously, spend virtuously, speak to fellow shoppers and clerks virtuously.” Are you at Mass? “I am going to do my part in this sacrifice virtuously.” Are you at confession? “I am going to confess my sins virtuously to the Priest and to Christ virtuously and resolve to amend my life virtuously.” etc.
What happens? The new life in your soul, the soul infused with Virtue, is now in the material world also, and not just in your soul. Now your “body”, including your brain and physical thoughts, is a true representation of your soul.
