There is not much ritual cannibalism anymore, but it may still be found in uncontacted tribes in New Guinea, or, the Amazon.
Cannibalism due to famine, or, other circumstances where hunger is present is more common than you would think, and people will resort to it sooner than expected.
When I was serving in the US Navy, I was involved in several medical humanitarian missions in a country that was just coming out of a famine. There were rumors of cannibalism. I never saw anyone eating another person, but these people were so torn up, so hopeless, and in a state of dispair. To be honest, it was the worst thing I ever saw in my life. It is possible that they had been impacted by the amount of death they were exposed to, and the murder, rape, violence, and abuse that accompany a societal collapse. My personal feeling is they ate each other to survive.
If this is some effort to make a case that communion is cannibalism, nice try, but I will not entertain your efforts.
