St. Michael and St. Joseph are basically viewed as the Church's champions against the wiles of Satan. Pope Francis and Pope Emeritus Benedict recently showed up to consecrate the Vatican to both of them. That this is a big deal is, I think, obvious given the fact that Benedict showed up.
Per Zenit, here is the relevant excerpt from the Holy Father's comments:
Dear brothers and sisters, we consecrate Vatican City State also to Saint Joseph, the custodian of Jesus, the custodian of the Holy Family. May his presence make us stronger and more courageous in making space for God in our life to overcome evil always with good. We ask him to guard us, to take care of us, so that the life of grace will grow every day more in each of us.
This isn't a new thing for the Pope. He previously had his entire pontificate consecrated to Our Lady of Fatima.
Considering all of the shenanigans going on in the Vatican for the last several decades, this is something sorely needed. It's good to see Pope Francis not only reminding people of these powerful agents of God, but also choosing to entrust them directly with protecting our patrimony.
