That is exactly what the pope is saying...leave the dogmatic liturgical mumbo jumbo at home and tell folks of the gospel of grace.
The undeserved, unmerited, free gift of forgiveness and restoration that comes through the sacrifice made on the cross......IT IS FINISHED! Jesus paid the price for the sin of the world. God's wrath and fury was poured out upon HIS son. It is finished, we do not have to face God's wrath.
That is why in Catholic Churches, the cross has the body of Jesus on it as a REMINDER of that finished work.
That is what Jesus offers to us, by going to the cross for our sins paying for them by the shedding of His most precious blood.
