Someone said :
Don't they believe in it literally? So its insulting their intelligence to say that they do not actually think that it is actual man meat and man juice (blood) that they swallow. They do not think it is a symbol if you ask them or they would be protestants?
Or if not symbol then sacrifice-by-proxy.
The proxy-principal is also found in the weird continuation of emperor worship until 465AD despite Christianisation since 311AD, with Christians worshipping at statues of the divus Constantine. In Pagan times it was the emperor himself being worshipped, whereas under Christianity it was worship by proxy of God for appointing him. https://en.m.wikipedia.org/wiki/Apotheosis
