I will tell you now about what follows, about the blessing of the priest. People in the church sometimes leave before the blessing; sometimes they do not wait for it at all because they do not desire it. They do not understand what it gives them and why it is provided. You see, Christ, when departing from the earth, blessed it, blessed the apostles, and gave them His peace. This peace, which He left, is the beginning of Heaven. It leaves in the soul a longing for the immaculate, eternal peace.
The peace in God that we achieve on earth is imperfect, because it largely depends on ourselves; but even if we pray for peace during struggle, we will receive it. This concerns the peace of the soul in which one dwells in union with Christ. This peace is stronger than the attacks of the evil spirit, and it can be kept deep within the soul, even when everything around is full of unrest. The earth is not at peace. The more peace there is within us, the more Satan seems to kill this peace. However, the Holy Spirit multiplies this grace within us when we really need it. Christians should not be afraid of any events, because they are embraced by the grace of Christ. This grace, which protects them, strengthens them and makes them independent from the world, flows out from the blessing. Through the sign of the cross that the priest makes over the faithful, the Holy Spirit provides graces at the measure of the opening of the soul to that grace; and depending on the Will of God, it flows in a different way on different souls.
When departing, Jesus blessed the apostles, so they may carry His peace to their homes. This peace is abiding in Him. Only such a peace is durable. The blessing provides us with the grace of the presence of Christ, who acts in this blessing through the power of the Holy Spirit. Without this blessing, we would not be able to do anything. Each blessing that we take away after the Holy Mass, comes out form Heaven into the world and acts, acts by transforming and shaping the world in the image of God.
The road of every blessing is far-reaching in its consequences. It sometimes reaches very far and brings goodness in places where it can not to be expected at all. Thus, always take the blessing and ask for it. The blessing is a direct pull of graces from Heaven for our needs, our miseries and our anxieties. It is the peace of God, which by descending, transforms the world.
I want you to further pass down the blessings that you receive from priests. Not only they can bless. In the Name of God, the Spirit gives Himself to those who believe, and He only seeks souls thirsty for His graces. The blessing surrounds those who ask for it and receive it with love. I bless you daughter. Amen.
