Well, when I was a Catholic, many moons ago, it was just flat, tasteless bread, not nice wafers, like in your picture. When I was around 12, I knew I was always committing mortal sins, so I stopped receiving holy communion, because I didn't want to commit a mortal sin of sacrilege. A mortal sin was bad enough, but a mortal sin of sacrilege, was far worse. Kind of like the unpardonable sin.
Sometimes I couldn't sleep at night, because I was worried about the mortal sins on my soul. My dad started to wonder, and asked if I needed to go to confession? I didn't pay much attention in catechism class, so I was always at a loss, to determine what was a mortal sin, and what was a venial sin. Venial sins were ok, it was the mortal sins I wanted to avoid.
As you know, I don't indulge anymore. Praise God for that, but I looked back on my life, and I could see God preparing me for TRUE faith, as opposed to false faith, all the way back to when I was a Catholic. If I had been a Mormon, they would have called me Jack. 😄😂😄
