"the more perfect a virtue is, the more does it cause passion"

"it is not the function of virtue to deprive the powers subordinate to reason of their proper activities, but to make them execute the commands of reason by exercising their proper acts"; to "direct the sensitive appetite to its proper regulated movements" of ordered or "moderated passion."

     St. Thomas Aquinas, Summa theologiae I-II.59.5.Resp. & ad 1-2, trans. FEDP (i.e. Shapcote).  Virtue calls for the moderated or ordered passion that both 1) "helps towards the execution of reason's command" and 2) "results from" the said acts or execution.
