“I want to be among you as a missionary of the mercy and tenderness of God.” – Pope Francis said – “But allow me to encourage you, too, to be missionaries of this infinite love of God. May no one be without the witness of our faith, of our love. May everyone know that God always forgives, that God is always at our side, that God loves us.”
