Why is Missing Sunday Mass Considered a Sin?

I’ve been asked this question many times before. To answer it, one has to understand the mass. It is a reliving of the sacrifice of Jesus in Calvary. In doing so, we also commemorate the sacrifice he made to “save” us. Let’s draw an analogy. Suppose your father fought during WWII and died in the war. It’s only proper to honor the sacrifice he made to “save” you from fascism. If you refuse to go to his memorial service, then this would be a grave insult. Refusal to commemorate the sacrifice he made would send the message that you don’t care that he died for you. It further implies that what he did was not important to you. How do you think his dad, your grandfather, would feel about that? I think he would be deeply hurt and offended by it. So ask yourself, how do you think God the Father would feel, if you refuse to commemorate the fact that His Son Jesus gave His life to “save” you from eternal damnation? Do you now see why it’s considered a serious offense to deliberately miss Sunday mass without any legitimate reason?

How I Came to Believe in the Real Presence

I said I believed the Eucharist is Jesus. I didn't believe it at first. One day, my mom was taken to the hospital. She was seriously ill & her condition was worsening. At a retreat, I asked a priest why God allowed it. He said, "Ask our Lord in the Tabernacle." So I did & I asked for her cure. I got a Bible & chanced upon John 4:47-54, about the cure of an official's son. This occurred on Saturday. When I came home, I called the hospital & found out that mom was better. I asked her when her condition turned around. She said, "On Saturday." Coincidence? On Monday, a Protestant asked me why I visited the church on weekdays. I told her what the priest told me, "to visit our Lord in the Tabernacle." So I invited her to church. Later, she told me, "I found what I'm looking for." So she became a Catholic. I asked myself, "Can bread bring about conversion?" Another person told me he had a problem & had been praying for weeks for a solution. When he asked me what to do, I said, "Pray to our Lord in the Tabernacle." So I invited him to church on Friday. On Monday morning, he told me his problem was solved. These could not be just coincidences. So from that day onward, I was convinced that the Eucharist was truly our Lord Jesus, and not just a piece of bread.
