Watch the Mass anytime, anywhere. Download the CatholicTV app on your smartphone/TV or watch everyday on our CatholicTV YouTube channel. Reminder, Sunday Masses are required for Catholics to attend in person, and the online Mass is not a substitute, unless you are sick, homebound, or unable to travel. As for daily Mass, which is a personal devotion that is not required, it can be a great practice to watch online if you are unable to attend! | The CatholicTV Network
