I find, often, that those who leave one religion and join another, express total hostility toward their former faith…but when they do this, its because they have “issues” with their former faith.
A convert who truly loves their new faith in and of itself, has no need to do that…they are able to focus on their new faith and forget about their old one.
I remember one ex-Roman Catholic I met a few years back…he went from Catholic to atheist, and out of sheer hatred for his former Catholic religion, he went to a Mass, received communion and took it home to abuse it.
Now, I do not at all believe in Catholic transubstantiation, and even though no Catholics knew he did this, I felt it was a wrong thing to do.
But there are people with serious issues about their former faiths…I’ve known Jews who left Judaism out of some resentment, and while they may have chosen to eat pork out of spite, I’ve never heard of any who would go so far as to desecrate a Torah scroll or something like that (God forbid!)
So for a guy to desecrate a Catholic communion wafer, to me, really tells me he had Issues (with a capital I!)
