He is known for his profound devotion to the Blessed Sacrament.
In his words:
How kind is our Sacramental Jesus! He welcomes you at any hour of the day or night. His love never knows rest. He is always most gentle towards you. When you visit Him, He forgets your sins and speaks only of His joy, His tenderness and His love. By the reception He gives to you, one would think He has need of you to make Him happy.
Go to your adoration as one would go to Heaven, to the Divine Banquet. Tell yourself, "in four hours, in two hours, in one hour, Our Lord will give me an audience of Grace and Love. He has invited me, He is waiting for me, He is longing for me".
