This is purely paganism, an irresponsible, foolish interpretation of the Scriptures. It shows a shocking lack of discernment upon the part of an entire religious organization, and I absolutely cannot believe that normally rational people can read the words of Christ and think that HE was talking about a literal consumption of His flesh. Really!
Then read more carefully...ALL Christians for over 1,600 years believed exactly that and real/complete Christians (Catholics) still do...
