The thing about heroin, man, is if you don't get it, you should just steer clear away. 

That's a lesson that Vatican culture minister Cardinal Gianfranco Ravasi hopefully learned in the wake of a truly embarrassing tweet posted in the wake of the musical icon Lou Reed's Sunday passing.

Ravasi, a 72-year-old native of Merate, Italy, was evidently touched by the influential singer's death—so moved, in fact, that he was summoned to post his first English message to his 57,000 followers on Twitter. That's cool, and, to Catholics who also happened to be big time Velvet Underground fans, probably truly appreciated.

What he chose to tweet, however, should be cause for concern—at least in regards to the Cardinal's understanding of Lou Reed's whole ethos.

Looks nice and harmless, right? Wrong! Those four lines come from Reed's track "Perfect Day," featured on the heroin-abuse flick Trainspotting. The song's lyrics are vague, but it's come to be closely associated with drug addiction.

A common reading of the song posits that "you" that Reed was glad to spend the "perfect day" alongside wasn't a person, but rather that sweet white horse. And the "you" that keeps him "hanging on" is the same damn thing: a whole mess of highly illegal, very very dangerous heroin. 

Who are we to say, though? Maybe Cardinal Ravasi knew the subject's nature all along. After all, Reed did say the stuff made you "feel just like Jesus' son."

Correction: An earlier version of this article misattributed the lyrics to the song "Heroin." We regret the error.
