“Some of this occurred to me as I watched this KIA commercial the other day.
It is filled with unexpected things. A rather well-heeled couple comes to the valet to get their luxury car. And yet a strange Christ-figure meets them and challenges to take the risk of a different ride. He tells them that the world of luxury has blinded them from the world of true luxury. (Pay attention, Christian!) He offers them a blood-red key (that brings to mind the Cross) to a different ride than their worldly luxury car.
At some point the couple is led to a KIA car”
So it is Ok to use our Blessed Savior and Catholic teachings to sell cars but it is wrong to use them to teach the message of holiness and piety.
You've got it exactly backwards (neither Msgr. Pope nor the Church wrote the ad). It is finding the holy in the everyday.
