You are what you eat (allegedly)

I'm now in a Telford hotel room, just a few miles from where the local BBC news has reported that a special "God's Acre" service has recently been carried out on the grave of Richard Munslow, the last known sin-eater in England, at St Margaret's Church, Ratlinghope.

The Reverend Norman Morris explained that "It [Sin-eating] was a very odd practice and would not have been approved of by the church, but I suspect the vicar often turned a blind eye".

The BBC report also helpfully explains that sin-eaters were generally poor people who were paid to eat bread and drink beer or wine over a corpse, in the belief they would take on the sins of a person who had died suddenly without confessing their own sins, and so allow the deceased’s soul to go to heaven in peace.

So logically, as a sin-eater wouldn't have been able to acknowledge these unknown sins prior to their own demise, and would therefore always need someone to consume their unconfessed sin collection, isn't it surprising that there were ever any believers unable to see the flaws in it as a career choice?
