Magdalene,

If you personally know that you shouldn't be shopping on a Sunday and place the blame on the Holy Father as an excuse, are you not also accountable for your actions?

Pinoy Monk

A Pope also concocted the Novus Ordo Mass. The N.O. is still the Holy Sacrifice and is pleasing to God. Yet, the way the Holy Sacrifice is prayed and offered is not pleasing to God because it is a Protestantized version. However, is it sinful for me to attend a N.O. because the Church made it the form of liturgy. No. I do not sin at all by attending the N.O. Mass (if there is no TLM, I infact have to attend the N.O. to fulfill my Sunday obligation). And the same way that, although it is more pleasing to God that we not shop on Sunday, the current Church has not said specifically that it is sinful. And so I do not sin by going to eat at a restaurant or going to the grocery store for food on Sunday, although it is preferable and more pleasing to God not to.
