How can we return to living a life of grace? This means first of all having large families. You will never get any significant number of vocations from families of 2 - 3 children. Secondly it means living a life of traditional devotion. Daily family rosary. The traditional Catholic Mass. Offering our sufferings in reparation. Embracing mortification and humility.
Perhaps I skipped over it too quickly, but I didn't notice these things in the article. Praying for vocations won't work. But praying for forgiveness of our sins might.
