As these quotes indicate, the Blessed Sacrament was "essential" in the lives of Venerable Matt Talbot and (newly recognized) Venerable Fulton J. Sheen:
"You know that Matt Talbot, the Dublin workingman, found in the Blessed Eucharist his support and his strength? As a young man he was a slave to drink. He took the pledge and kept it. But who can tell what it cost him? When the temptation was fiercest Matt would
make his way to the church and sit there. "I'm safe as long as I stay here"!”

"How can anyone be lonely, with Our
Lord in the Blessed Sacrament?"
"The secret (to my preaching) is that I have never in fifty-five years missed spending an hour in the presence of our Lord in the Blessed Sacrament. That's where the power comes from. That's where sermons are born. That's where every good thought is conceived."
