Someone close to me is fond of using St. Augustine's quote, "Love, and do what thou wilt." And I guess that depends on whether one understands what God means by love.
But what does it actually mean? Be charitable..and do whatever else you want? How to discern the meaning?
Please forgive my ignorance in this matter. I couldn't find anything online...and maybe it's too lofty for me to consider. But I wanted to have an answer for person who is using this phrase.
